Changelog

v1.40.1 — 2026-07-23

• Rooms are no longer clickable in View (default cursor, empty space does nothing). Instead the room card shows a small open-in-new icon after the name — clicking it opens the HA area. Rooms without an area (and all editors) have no icon.

v1.40.0 — 2026-07-23 (smart guides)

• Alignment helper in every editor: while drawing an outline, a cut or a decor shape, and while dragging icons, room cards or decor, thin dashed guides appear from the nearest object sharing your X and/or Y (one per axis, with a marker dot at the source) — lamps line up, lines end exactly above the end of a parallel line. Candidates follow the context: room vertices and path points in the Plan editor, other icons in the Device editor, decor endpoints/corners plus room vertices in the Background editor, other room cards while dragging one.
• The cursor badge now shows length · angle and turns green when the segment's angle is a multiple of 45°. Guides are pure indication — the grid keeps owning the actual position.

v1.39.0 — 2026-07-23 (lights toggle by default)

• Pure light sources — devices whose primary entity is a light (bulbs, chandeliers, night lights, light groups) — now toggle on click by default, right from auto-placement, no per-device setting needed. Devices where light is a side function (a kettle's backlight: its primary is a sensor) keep the Device-card default. An explicit per-device choice always wins. The device dialog shows the effective default.

v1.38.4 — 2026-07-23

• Plan editor: the DERIVED wall segments (the markup layer's solid lines) are now trimmed under open boundaries as well — v1.38.3 only trimmed the room outlines, so the virtual wall still looked solid in the editor. (cutSegments extracted as the shared workhorse; outlineWithout reuses it.)

v1.38.3 — 2026-07-23

• The Plan editor now shows open boundaries as a true dash as well: the blue markup outlines are trimmed under the open stretches (rooms picked for merge/split keep their full amber highlight).

v1.38.2 — 2026-07-23

• The card now remembers where you were: the selected space and the active editor survive navigation and closing the tab (localStorage; edit modes are restored for admins only). A #space= deep link still wins over the saved space. This reverses the earlier "always start in View" rule — the owner's call.

v1.38.1 — 2026-07-23 (tap action cleanup, right-click more-info)

• The per-device action is now one of three: Device card (renamed from "Info card", the default), HA more-info, Toggle. The confusing "As the card default" option is gone — along with the card editor's global tap setting (it is ignored if present in old configs). Explicit per-device choices are untouched. RU wording: «по нажатию» instead of «по тапу».
• Right click on a device icon in View mode always opens HA's more-info dialog (editors keep the native browser menu; a virtual marker without an entity opens its device card).

v1.38.0 — 2026-07-23 (binding section redesign)

• The device dialog's binding section is compact now: two radio buttons — Virtual device and Pick from the HA list — with a Show entities checkbox (adds every entity of the devices to the list; groups and helpers are always listed). The searchable dropdown appears only in HA mode and collapses once you pick. Save is disabled until a binding is chosen. The binding logic itself is unchanged.

v1.37.3 — 2026-07-23

• Open boundaries now render as a true dash: the rooms' solid outlines are trimmed under the open stretch (outlineWithout) instead of dashes being painted over a solid line, and the dashed layer moved above the glow pools so light never covers it.

v1.37.2 — 2026-07-23

• Glow falloff tuned: full brightness for the inner 70% of the radius, gradient on the outer 30% (was 80/20).

v1.37.1 — 2026-07-23

• Open-boundary tool polish: the cursor stays default and only turns into a pointer near a wall shared by two rooms; hovering previews the exact stretch that would become open (amber dashed) — or red solid when the boundary is already open and the click would close it.

v1.37.0 — 2026-07-23 (open boundaries — virtual walls)

• Rooms divided only by zoning can now share an open boundary: the new "Open boundary" tool in the Plan editor toggles it with a click on the wall two rooms share. The stretch renders dashed; while the tool is active open boundaries highlight amber. Stored as room.open_to links by room id, so redrawing/merging neighbours doesn't break them.
• In the light-sources fill, light flows through open boundaries freely — transitively across the whole connected zone (kitchen ↔ living ↔ hall as one open space), still limited by the glow radius. Door sectors now work from any outer wall of the zone.

v1.36.4 — 2026-07-23

• Glow: sharper light edge — the pool is fully lit for the inner 80% of the radius, the gradient falloff lives only in the outer 20%.

v1.36.3 — 2026-07-23

• Glow: fixed dark wedges appearing INSIDE a lit room near some doorways. The room outline and the door sectors were subpaths of a single clip path; with opposite winding directions the nonzero fill rule cancelled their overlap. Each contour is now its own clipPath child (children always union), so sectors only ever ADD light.

v1.36.2 — 2026-07-23

• Glow radius is now per source: every device dialog gained a "Glow radius" field (in your HA units; empty = the global default from general settings, shown as the placeholder). A kettle's night light can glow half a meter while the ceiling lamp floods the room. Door sectors use the same per-source radius.

v1.36.1 — 2026-07-23

• Fixed tap-toggle "doing nothing" on lamps whose individual light.* entity is hidden in the registry (the usual setup when lamps are folded into a light group): the primary entity fell through to a visible config switch (do-not-disturb) or an identify button, and the click toggled THAT. Primary selection now works in tiers — domain priority beats hiddenness, so a hidden light still wins over a visible config switch, while visible entities of the same domain keep winning over hidden ones.

v1.36.0 — 2026-07-23 (wall switches that really switch)

• Markers gained "Controls light sources": bind any set of light.* / switch.* entities to an icon. With tap action Toggle, a click flips them all with HA-group semantics — any on → all off, all off → all on — in one service call. Covers stateless remotes, one-switch-many-lights and dumb wall switches (place a virtual marker; no HA entity needed).
• The icon mirrors its targets: on when any target is on, tinted by the first lit RGB light. The info card lists every target with its state. Controls fire only on the explicit per-marker Toggle (owner's decision); locks and other domains can never be group-controlled.

v1.35.0 — 2026-07-23 (glow fill: dark house, glowing lamps)

• New fill mode "Light sources": the whole house is painted with a single configurable darkness color, and every lit lamp casts a radial pool of light around itself. The pool color comes from the lamp's rgb_color, else its color temperature (blackbody conversion), else a configurable default; brightness scales the intensity.
• Pools are clipped by the source's room — plus the sector through each doorway (rays from the source to the door edges, out to the glow radius), so light spills into neighbouring rooms through doors. Entrance doors (no room behind) spill nothing; windows don't spill. No shadow casting: islands and furniture do not block light (deliberate limitation).
• The glow radius is configured in General settings in your HA unit system (meters or feet; stored in cm, default 3 m). The palette gained a "glow" group: house darkness + default light color/intensity.

v1.34.0 — 2026-07-22 (island rooms)

• Nested rooms are now legal: draw a contour fully inside an existing room (or around one) — a column in a ring-shaped room, an inner room, a wardrobe island. The parent room's fill is rendered with an evenodd hole, so a ring paints as a ring; the island itself stays clickable and can carry its own area, fill and devices. Partial overlaps and duplicate outlines are still rejected (roomsOverlap reworked; polyContainsPoly/islandsOf helpers, unit-tested). The per-click "point inside a room" rejection is gone — validation happens once, when the outline closes.

v1.33.5 — 2026-07-22

• Editor tabs got extended tooltips explaining what each editor is for (plan geometry vs device icons vs visual decor).

v1.33.4 — 2026-07-22

• Editing a device no longer makes its icon jump. Changing the HA binding (which changes the marker id) migrates the saved position to the new id; changing the room within the same space keeps the icon exactly where it stands (previously it re-centered in the new room). Only a brand-new icon, or a move to a room in a different space, is centered.

v1.33.3 — 2026-07-22

• Device dialog: when no icon is set explicitly, the icon picker no longer looks empty — it shows the auto-derived icon (from the icon rules / device class) as a placeholder, with an "Auto: mdi:…" hint line underneath. Picking an explicit icon replaces it as before; clearing returns to auto.

v1.33.2 — 2026-07-22

• Removed the Reset button from the Device editor. It wiped the entire layout — positions of all devices, room cards and their scales across every space — behind a single confirm. Low value, high blast radius.

v1.33.1 — 2026-07-22

• The dot grid is now shown in every editor (Plan, Devices, Background), not just Plan — an instant visual cue that you are editing.
• In the Background editor, rooms, devices, openings and labels fade to 35% opacity so the decor you are drawing stands out; decor itself stays fully opaque. Other modes are unaffected.

v1.33.0 — 2026-07-22 (background editor)

• New third mode: Background editor. Draw purely visual decor on the plan — lines, rectangles, ovals and text labels that never interact with rooms, devices or fills. Shapes are drag-drawn with grid snap and a live preview; text is placed via a small dialog (size S/M/L, color; double-click to edit). Toolbar: Select (move, Delete key), Erase, color, three line widths and an optional 25% fill for rects/ovals. Esc walks back: draft → selection → Select tool → View.
• The decor layer renders under rooms (a true underlay), is visible in all modes and completely click-transparent outside the editor. Stored per space in the server config (space.decor, validated on the backend, shared across clients with the usual rev/optimistic locking).

v1.32.1 — 2026-07-22

• Opening tool: hovering near a wall now shows a dashed preview of where the opening would land — snapped onto the wall, default door length (90 cm), with a center dot. No preview far from walls or over an existing opening (a click there edits it instead).

v1.32.0 — 2026-07-22 (split polyline, tool cursors, Esc)

• Split can now cut along a polyline, not just a straight chord: start on a wall, click intermediate points inside the room, finish on another wall. The path is validated (no wall crossings, no self-intersection) and drawn live with vertices and a preview segment. Two clicks still work as before.
• Tool cursors: Merge and delete-room show a pointer; Split shows a pointer while picking the room, then a crosshair while cutting.
• Esc walks back out of Merge/Split step by step: last cut point → first point → room selection → back to the Draw tool. Merge: selection → tool.

v1.31.2 — 2026-07-22

• Plan editor: the room picked with the Merge tool (and the room selected for Split) is highlighted amber again. The .outlined markup style, added later in the stylesheet, was silently overriding the .picked highlight at equal specificity (source-order gotcha #4 — rule order fixed and documented in the stylesheet).

v1.31.1 — 2026-07-22

• Plan editor: interacting with a room card (drag, corner-resize or a plain click) no longer leaks into the active markup tool — previously the click after a resize could add an outline point, pick a merge/split room or even prompt to delete the room under the card.

v1.31.0 — 2026-07-22 (room cards)

• Room labels grew into room cards: the name on top, and an optional smaller metrics line below — temperature, humidity, average Zigbee signal and lights, each behind its own checkbox in the space settings (all off by default). Lights show On/Off, or "1 of 3" when only part of the room is lit. Rooms without an HA area keep showing just the name.
• Cards are resizable in the Plan editor: hovering shows corner handles; dragging one scales the whole card uniformly (0.5×–3×). The scale is stored in the layout next to the card position, and dragging keeps it.
• Fixed a latent v1.25 regression: room labels were not rendered as draggable HTML in the Plan editor at all (only a static SVG name), so moving them was impossible. The Plan editor now renders real cards (name only) that can be dragged and resized.
• Two markup smokes (merge/split) still called a method removed in v1.25 — repaired.

v1.30.4 — 2026-07-22

• Escape now closes every dialog (general settings, icon rules, device editor, space dialog, opening editor, info cards), topmost first when stacked. Closing the space dialog with Esc abandons a floor-import queue, same as its Cancel button. Esc while drawing an outline still undoes the last point (dialogs take priority).

v1.30.3 — 2026-07-22

• The General settings (fill palette) gear in the header is now visible in every mode for users who can edit, not just in the Plan editor.

v1.30.2 — 2026-07-22 (editor tabs redesign)

• Mode tabs renamed and reduced to two: "Plan editor" and "Device editor". View is no longer a tab — it is the implicit default state.
• The Device editor now has its own bottom toolbar (add / show all / reset layout / icon rules moved out of the header), mirroring the Plan toolbar.
• Both toolbars and the active tab itself got an X button that closes the editor and returns to View. Re-clicking the active tab does nothing; switching Plan↔Devices is direct.

v1.30.1 — 2026-07-22 (space gear polish)

• The gear icon next to the space name is now visible in every mode (not just Plan) for users who can edit, so space settings are always one click away. The "+" (add space) tab remains Plan-only.
• Fixed the gear's vertical alignment — it sat noticeably lower than the space name (baseline-aligned web component); tabs are now flex-centered.

v1.30.0 — 2026-07-22 (lock action in the opening info card)

• The door/window info card (View mode) now offers an explicit Unlock/Lock button when a lock entity is bound and available. Unlock is styled red as a security-sensitive action; the button is disabled during locking/unlocking and hidden when the lock is unavailable.
• The security rule is untouched: tapping a lock icon on the plan still never toggles it — the action lives only behind a deliberate, clearly labeled button, same interaction contract as HA's more-info dialog.

v1.29.0 — 2026-07-22 (the "new device" flag)

• Devices that appear in HA after installation no longer show up silently: an auto-placed device (or light group) gets a big red dot at the top-right of its icon. The flag is stored server-side (settings.new_device_ids), so every client sees it — and it disappears everywhere the first time someone opens that device's editor.
• The baseline of known devices is seeded silently on the first run after the update, so existing devices never flood the plan with dots. Hand-made markers (virtual/rebindings) are never flagged — the user just created them. (Pure diffNewDevices, unit-tested; backend schema for the two new settings.)

v1.28.1 — 2026-07-22 (View-mode polish: cursors and inert openings)

• Device icons in View no longer show the grab cursor (drag lives in the Devices mode); they show a pointer — clicking still works exactly as before.
• Doors and windows in View are pure drawings: no grab cursor, no hover outline, no hit target, no click — regardless of what is bound to them.
• The lock badge is the one exception: when a lock is bound, the badge is shown and clickable in View (pointer cursor, click opens the door/lock info card). It stays inert in Plan so it does not fight editing.
• In Plan an opening remains fully interactive: grab cursor + hover outline, dragging along walls, and a click with ANY tool opens its properties dialog.

v1.28.0 — 2026-07-21 (sub-area rooms: manual placement without an HA area; issue #3)

• Devices can now be placed into rooms that have no Home Assistant area. The marker dialog's room list includes area-less rooms (marked "no area, manual"); pick one and the device/virtual marker lands at its centre. The marker stores room_id, so the choice survives edits and re-opens. The laundry-cupboard case from issue #3: a decorative room inside a larger area can now hold its own door sensor and light.
• Room reference parsing extracted as pure parseRoomRef (space#area / space#@roomId), unit-tested; backend schema for room_id.

v1.27.0 — 2026-07-21 (RGB light colors + alarm pulse; issue #3)

• RGB lights show their actual color: an "on" light with a color tints its bulb icon, glow and — unless a custom ripple color is set — its presence ripple. Brightness is deliberately ignored (a dim red bulb still reads red); off, white-only and unavailable lights look as before. (Pure lightColorOf.)
• Emergencies pulse red: leak / smoke / gas / CO / safety / tamper / problem binary sensors and sirens in on get a red pulsing ring over any display mode. unavailable/unknown never alarm — an outage is not a fire. Honours prefers-reduced-motion. (Pure isAlarmState.)

v1.26.0 — 2026-07-21 (state-reflecting icons + value display; issue #3)

• Auto icons now reflect live state, like core HA: door/window/garage sensors swap open↔closed variants, locks show locked/unlocked, a bulb lights up as lightbulb-on. Conservative by design: only well-known pairs, never when the user picked a custom icon, and unavailable/unknown keep the base icon. Gated by the existing "live states" card option. (Pure stateIcon, unit-tested.)
• New marker display mode "Value instead of an icon": the measurement itself (temperature °, humidity %, or any numeric state with its unit) becomes the marker body — the small corner badges disappear for such markers. Direct request from issue #3. Non-numeric entities fall back to the icon.

v1.25.0 — 2026-07-21 (three interaction modes: View / Plan / Devices)

The approved UX redesign (docs/UX-MODES.md), confirmed by user feedback (#3):

• View (default, and the only mode after every load): display and device interaction only — tap/long-press/tooltips/pan/zoom. Nothing can be dragged or edited; panning may start on top of an icon and never displaces it. The header carries only space tabs, the counter, zoom and the mode switcher.
• Plan: everything about geometry and appearance — room outline/delete/merge/ split tools, openings (placement, drag along walls, click-to-edit), room-label dragging, per-space gear dialog, add space, the ⚙ fill palette. Orange stage frame.
• Devices: marker work — icon dragging lives ONLY here, a click opens the editor directly; add device, show-all curation, reset layout, icon rules. Accent frame.
• The mode switcher is a segmented control shown to administrators; the standalone markup toggle button is gone, "drag anywhere" (v1.9) is consciously reversed, and the v1.23.1 view-mode opening drag/double-click moved into Plan.

v1.24.2 — 2026-07-16 (lights fill: a color for rooms with no light sources)

• The "Fill: lights" group in General settings gained a third color — "No light sources". Its default opacity is 0, so rooms without any lights stay unfilled exactly as before; give it an opacity and such rooms get their own tint, distinguishable from "all lights off".

v1.24.1 — 2026-07-16 (space tab: gear instead of pencil)

• The small icon next to a space name in the tabs is now a gear (was a pencil) — the dialog it opens is space settings (plan, display, scale), not just renaming.

v1.24.0 — 2026-07-16 (general settings: fill palette; per-space LQI toggle)

• New "General settings" dialog (⚙ in the header): the fill colors used by every space, grouped by mode — lights (on / all off), temperature (cold / comfortable / hot) and zigbee signal (weak / strong endpoints of the gradient). Every color has its own opacity slider; the zigbee fill interpolates between the two configured endpoint colors. Stored server-side in settings.fill_colors (defaults are not persisted); the static houseplan-space-card uses the same palette.
• Per-space "Show zigbee signal (LQI)" toggle in the space dialog: hides or shows the LQI badges next to zigbee devices (and the signal line in room tooltips) for that space; when never touched, the card-level show_signal option applies as before.
• Fill opacity is now governed by the per-color setting; the space "Opacity" slider keeps controlling borders and names.
• New pure helpers fillColorsOf / lerpColor / roomFillStyle (+4 tests: 77 → 81); backend schema for fill_colors and show_lqi; smoke smoke_general_settings.

v1.23.2 — 2026-07-16 (manual upload limit raised to 50 MB)

• The per-file limit for attached manuals (PDF etc.) is now 50 MB (was 25). The limit is still enforced while the multipart body streams in, so an oversized upload is cut off early rather than buffered whole; the error toast reads the actual limit from the server response.

v1.23.1 — 2026-07-17 (openings: hover, drag along walls, double-click properties)

• Hover affordance: an accent outline hugs the opening's wall strip on hover, with a grab cursor — placed openings now look grabbable.
• Drag along walls (view mode): an opening re-snaps continuously to the nearest derived wall while dragged; too far from any wall → it stays put. snapToWall now normalizes the angle to [-90, 90) — two rooms share a wall with OPPOSITE edge directions, and without this a drag across segment boundaries flipped the hinge side back and forth. Saved on release.
• Click / double click: a single click still opens the status card (now via a 250 ms timer); a double click opens the properties dialog right from view mode. The markup "Opening" tool behaves as before. Hit zone made slightly thicker and is now a strip along the wall (previously it covered the whole swing square, causing accidental hovers).
• (+1 test: 76 → 77.)

v1.23.0 — 2026-07-17 (doors & windows with live open/lock state)

Visual language after easy-floorplan (MIT); the placement model is ours.

• New markup tool "Opening": click next to a wall → the opening snaps onto the nearest DERIVED room wall (walls have no independent existence — v1.19.0) and takes its angle, then a dialog asks for type (door/window), length in real cm (defaults: door 90, window 120 — the per-space scale makes this honest), an open/close sensor (door/window-class binary_sensor/cover, invertible) and, for doors, a lock entity. The opening keeps absolute coordinates, so editing/merging/deleting rooms never breaks it. Click an existing opening with the tool to edit or delete it.
• Live rendering: a door is a leaf hinged at the jamb with a quarter-circle swing arc that "draws on" (stroke-dashoffset) as it opens; a window is two casement leaves meeting in the middle. Открыто → the moving parts take the accent colour and animate (CSS transitions, prefers-reduced-motion honoured). No sensor → the classic static plan: doors drawn open, windows closed. unavailable/unknown freeze that default — an outage must not fake motion (pure openingAmount, unit-tested). Hinge side / swing side via flip toggles.
• Locks: a padlock badge beside the door — green closed when locked, orange open when unlocked, grey question when unknown. The lock is NEVER toggled from the plan (the card's standing security rule); clicking the opening or the badge shows an info card with both states.
• New pure helpers snapToWall (projection + wall angle over derived edges) and openingAmount; space.openings[] validated server-side. (+2 tests: 74 → 76.)

v1.22.0 — 2026-07-17 (presence ripples, per-device icon size/rotation, one-click install)

Ideas borrowed from easy-floorplan — the visuals, not the model.

• Presence ripples: display: badge | ripple | icon_ripple per marker, with ripple_color and ripple_size. Active → pulsing rings; idle → a faint dot. Gated by the pure isActiveState — independent of the card-wide live_states toggle, and unavailable/unknown count as idle so an outage never leaves a ring pulsing. Honours prefers-reduced-motion.
• Per-device icon size (×0.5–3) and angle — sizing now hangs off --dev-size, so value badges scale with the device.
• One-click install badge (My Home Assistant → HACS) in both READMEs.
• (+1 test.)

v1.21.3 — 2026-07-16 (room labels: no text shadow)

• Room name labels no longer carry a text shadow — crisper look on both the white hand-drawn canvas and plan images.

v1.21.2 — 2026-07-16 (space-dialog polish)

• The "Scale (cm per cell)" input is compact again — a generic width:100% dialog rule was stretching it across the row.
• A space with no background image now gets a white "paper" canvas instead of the dark stage, so hand-drawn rooms read like a floor plan on paper.

v1.21.1 — 2026-07-16 (audit: split snaps to the wall, docs for merge/split)

• Fix (found in audit): Split required each click to land on a grid node, so it silently refused rooms whose walls are not grid-aligned (imported or older polygons) — the "pick a wall" toast fired no matter where you clicked. The click now snaps to the room's nearest wall (closestPointOnBoundary) instead of the grid, with the pull capped at ~6 grid cells so an accidental click in the middle of a room stays a miss rather than becoming a wall point the user never meant; splitRoom() still rejects a cut that is not a clean wall-to-wall chord. Also makes aiming easier on the fine (240-cell) grid.
• Docs: README (en + ru) now documents room Merge, Split, the drawing ruler and the per-space scale — these v1.18–v1.21 features were shipped without user-facing docs. docs/TESTING.md gained merge/split rows and a fresh self-run record.
• New smokes demo/smoke_merge_split.mjs and smoke_split_nonsnap.mjs; closestPointOnBoundary unit-tested. (+1 test: 72 → 73.)

v1.21.0 — 2026-07-16 (merge and split rooms)

• Merge (toolbar "Merge"): click a room, then a neighbour. Only rooms that share a wall can merge — and that is decided by the result rather than a heuristic: mergeRooms unions the outlines and accepts the pair only when they collapse into ONE hole-free outline. A corner touch, rooms apart, or a union enclosing a hole are refused. A dialog picks which name and area survive; the kept room keeps its id, so its label position and devices stay put. The dialog warns that the other area is released.
• Split (toolbar "Split"): click the room, then two points on its walls — the chord cuts it in two, with the live ruler on the cut. The bigger part stays the room it was (name, area, devices); the smaller becomes a new room and its dialog asks for name/area. Cancelling the dialog leaves the room whole — the cut is applied only on confirm. Cuts that do not run wall-to-wall inside the room (ends off the wall, chord leaving a concave room, a chord along a wall) are refused.
• Boolean geometry via polyclip-ts (proper ESM + native types; polygon-clipping ships named types but a default-only ESM build, which breaks either tsc or the runtime). Verified against the real plan, where neighbouring walls overlap collinearly instead of matching exactly — the case a hand-rolled union gets wrong. Bundle: 151 KB → 202 KB.
• New pure helpers: polygonArea, mergeRooms, splitRoom. (+5 tests: 67 → 72.)

v1.20.0 — 2026-07-16 (rooms may not overlap)

• A click strictly inside an existing room is refused while drawing (toast names the room). Being on a wall stays legal — neighbouring rooms share walls, and real walls overlap collinearly rather than match exactly, so new vertices land on existing outlines mid-span all the time. pointStrictlyInside excludes the boundary explicitly (ray casting alone is unreliable exactly on an edge).
• Closing an outline that overlaps an existing room is refused — vertex checks alone are not enough: an outline drawn around a room has every vertex outside it. The outline stays open so it can be corrected. Nesting one room inside another counts as an overlap.
• New pure geometry in logic.ts: roomPoly, pointOnBoundary, pointStrictlyInside, segmentsProperlyCross (touching/collinear is deliberately not a crossing), roomsOverlap (edge crossings + containment probe, which also catches duplicate outlines). (+4 tests: 63 → 67.)

v1.19.0 — 2026-07-16 (a line is never a thing of its own)

Model change. A wall can only exist as an edge of a closed room. Consequences:

• Walls are derived from room outlines (roomEdges in logic.ts), not stored. A wall shared by two rooms is emitted once, so deleting a room keeps the borders its neighbours still contribute — and drops the walls nobody else uses. This falls out of the model instead of needing bookkeeping.
• An abandoned outline leaves nothing behind. Previously every click pair was written to space.segments immediately, so a contour you never closed left orphan lines on the plan. Now nothing is persisted until the room is saved.
• The "Erase line" tool is gone — there is no standalone line to erase. Mis-clicks are undone with Esc / Ctrl+Z as before.
• space.segments is dropped on every save (legacy configs shed it on first write). Validation still tolerates the field so a stale browser tab cannot fail a save; diagnostics no longer reports it. Lines that belonged to no room disappear on upgrade — by design.
• Dead code removed: _addSegment, _removeSegmentByKey, _distToSeg, _pathSegs, _segKey. segKey(a, b, prec) gained a precision argument (normalized coords need more than render units). (+2 tests: 61 → 63.)

v1.18.1 — 2026-07-16 (fix: the drawing ruler was invisible)

• Fix on top of v1.18.0: the length badge never showed up while drawing. It was rendered inside .devlayer, and .stage.markup .devlayer { display: none } hides that whole layer in markup mode (so icons do not get in the way) — the badge was in the DOM but invisible. It now lives in its own .measurelayer (absolute, pointer-events: none), which markup mode does not hide. Verified visually on a real drawn segment ("3.60 m" on screen).
• Testing lesson (see docs/TESTING.md): asserting on textContent is not enough — a DOM query passes on elements hidden by an ancestor. Check offsetParent/rect or look at a screenshot.

v1.18.0 — 2026-07-14 (live measurements while drawing rooms + per-space scale)

• Ruler while drawing. In room-markup "draw" mode, a badge follows the cursor showing the length of the current segment (last placed vertex → cursor). Units come from the HA unit system: metric → metres ("1.25 m"), imperial → feet+inches ("4′ 1″").
• Per-space scale. New "Scale (grid cell size)" field in the space dialog — cm represented by one grid cell (default 5 cm, i.e. 240 cells ≈ 12 m). Stored as space.cell_cm; each plan can have its own real-world size.
• Pure helpers segmentCm / formatLength in logic.ts (unit-tested); _fmtLen + _renderMeasureLabel in the card; .measurelabel style; i18n space.scale_label/scale_unit. (+3 tests: 58 → 61 frontend.)

v1.17.2 — 2026-07-11 (humidity badge: gate on the sensor, not the icon)

• Fix on top of v1.17.1: the humidity % badge is now shown whenever the marker's primary entity is a humidity sensor (device_class: humidity), regardless of the resolved icon. Previously it required the mdi:water-percent icon, so a humidity sensor whose name matched another icon rule (e.g. a "Myheat Влажность …" sensor → boiler icon) showed no value. Verified live (45.2 → 45%). (+1 test: 57 → 58.)

v1.17.1 — 2026-07-11 (humidity value next to the icon, like temperature)

• Humidity sensors now show their value (%) next to the icon, mirroring the temperature badge. Any marker resolved to the humidity icon (mdi:water-percent) — a humidity device or a humidity entity placed on its own (v1.17.0) — gets an integer % badge and the value in its tooltip. New isHumEntity/humFor (diagnostic entities excluded), DevItem.hum, .hval badge, gated by the same "sensor values" option as temperature. (+2 tests: 55 → 57.)

v1.17.0 — 2026-07-11 (place individual entities, not just whole devices — issue #1)

• You can now put a single entity on the plan as its own icon — e.g. a climate sensor exposes temperature AND humidity; add the device (shows temperature) and separately add the humidity entity as a second icon. In the "add device" dialog, start typing in the binding search and individual entities now appear alongside devices/helpers (surfaced only while searching, so the default list stays clean); the sub-label shows the domain and parent device.
• Entity markers now get a sensible auto icon (name rules → device_class → chip) instead of the generic shape, and a temperature value when the entity is a thermometer/air-monitor. The entity:<eid> binding already existed (used by helpers/light groups); this exposes it for any entity. (+1 test: 54 → 55.)

v1.16.2 — 2026-07-11 (docs+log: correct card resource URL — fixes "Custom element doesn't exist")

• Support issue #2: users adding a Lovelace resource that points at the on-disk path /custom_components/houseplan/frontend/houseplan-card.js get a text/plain MIME error and "Custom element doesn't exist: houseplan-card" — HA does not serve custom_components/ over HTTP. The integration serves the card at /houseplan_files/houseplan-card.js (verified: 200 text/javascript) and auto-registers it as a Lovelace resource in storage mode.
• README (en+ru) now documents the correct URL and the common mistake, incl. a YAML-mode resources: snippet.
• On setup the integration logs (INFO) the exact served URL and, when Lovelace resources are YAML-managed, how to add it manually — so the fix is discoverable from the logs.

v1.16.1 — 2026-07-08 (space-card shows room fills as configured)

• The static houseplan-space-card now renders room fills exactly as configured on the full card (temperature / signal / lights coloring), as a snapshot of the states passed in via hass — reverting the v1.16.0 omission. The card still does not subscribe to state changes itself and stays non-interactive (pointer-events:none); fills refresh when HA hands the card an updated hass. Added shared areaLqi() in devices.ts.

v1.16.0 — 2026-07-08 (new: houseplan-space-card + deep-link)

• New second card custom:houseplan-space-card — a READ-ONLY, static schematic of a single space, embeddable on any dashboard. Draws the configured plan + room borders/names + device markers at their saved positions, with no interactivity (the schematic layer is pointer-events:none — no clicks/hover/tooltips/drag/more-info) and no live states (no state subscription, no status/temperature fills). A footer button opens the space in the full component via a deep-link (#space=<id>). Config: space (required), title, show_button, button_label, button_target, aspect_ratio, icon_size; unknown space → a tidy error card. GUI editor with a space dropdown from the integration config.
• Deep-link in the full card: on load it reads #space=<id> (valid id wins over default_floor) and listens to hashchange, without blocking manual space switching.
• Shared rendering: pure geometry in space-geometry.ts (unit-tested), the static drawer in space-render.ts, and a module-level config cache (config-store.ts, rev-keyed, seeded from the full card's localStorage snapshot, invalidated on houseplan_config_updated) so N embedded cards on one board share a single WS request. Both cards ship in the one bundle.
• Tests: 48 → 54 frontend (space geometry) + demo smokes smoke_space_card and smoke_deeplink.
• Note: status/temperature fills are intentionally omitted from the static card (they are live); it shows configured room borders/names + neutral icons. Marker/position edits reflect after the config event or a reload.

v1.15.6 — 2026-07-08 (room hover also reveals the border)

• Hovering a room now shows its outline even when borders are turned off. The stroke colour (--room-stroke) is now always set to the room colour and only hidden via --room-stroke-op — so the existing stroke-opacity: 1 on hover reveals a crisp border (previously the stroke was transparent when borders were off, so hover showed nothing).

v1.15.5 — 2026-07-08 (fix: room hover was always grey even when filled)

• Room hover now darkens the current fill for filled rooms and only greys unfilled ones (as intended since v1.15.1). The legacy .room.overlay:hover / .room.yard:hover grey rules were still matching styled rooms and, being applied to fill directly, beat the --room-fill variable — so a temperature/light/zigbee-filled room turned grey on hover. Scoped those legacy rules with :not(.styled); styled rooms are now governed only by .styled.filled:hover (brightness 0.78) and .styled:not(.filled):hover (grey).

v1.15.4 — 2026-07-08 (fix: device icon vertical centering — proper root cause)

• Root cause of the off-centre icon, found in the live app (the demo stub hid it): HA's real <ha-icon> host is display:block with a large inherited line-height (~22 px for a ~12 px glyph), so the SVG sat ~1.8 px below the badge centre. Fix: .dev ha-icon is now a zero-line-height flex box — the glyph centres exactly.
• Reverted the v1.15.3 box-sizing: border-box (it shrank the badge by 2 px and made the vertical offset more visible — "worse"). The 1 px anchor drift is instead corrected by the centering margin (-(size/2 + 1px)), keeping the original badge size.
• Verified in the real dashboard: anchor offset 0, glyph offset 0, badge size unchanged.
• Demo ha-icon stub made faithful to HA (block + line-height) so smoke_icon_center now actually reproduces and guards this; the smoke also asserts glyph-in-badge centering.

v1.15.3 — 2026-07-08 (fix: device icon 1px off its anchor point)

• Device icon badges were sitting 1 px down-and-right of their true point: .dev used the default content-box, so the 1 px border made the rendered square 2 px wider than the width the centering margin assumed. Added box-sizing: border-box — the badge centre now lands exactly on the device coordinate (verified in the demo: anchor offset 1 px → 0). The glyph itself was already centred within the square.

v1.15.2 — 2026-07-08 (fix: room average temperature counted non-thermometers)

• Average room temperature now uses only devices the card treats as thermometers (mdi:thermometer / mdi:air-filter). Previously areaTemp swept every device in the area through tempFor, so fridges, TRV heads and smart plugs leaked their readings into the average (e.g. a 8.3 °C valve/appliance temperature dragging a room down).
• isTempEntity now excludes chip/diagnostic temperatures: *_device_temperature sensors and any entity in the config/diagnostic category are no longer treated as a room temperature — so even a genuine thermometer no longer reports its chip temperature.
• Affects the temperature room fill and the room tooltip average. (+3 frontend tests: 46 → 48.)

v1.15.1 — 2026-07-06 (display-settings UX round from live usage)

• Comfort-bounds input hardening: clearing a temperature field can no longer collapse a bound to 0 (Number('') === 0 — this silently turned "comfort from 25" into a 0–25 range after the auto-swap, showing green at 24°). Inputs now parse with parseFloat + isFinite guard and the save path falls back to the defaults for non-finite values.
• Room tooltip now shows the average room temperature (what the temperature fill actually uses — averages every thermometer in the area, including TRVs).
• Hover no longer recolors rooms blue: filled rooms darken their current fill (brightness(0.78)), unfilled rooms get a light grey tint.
• Fill mode selector is a radio group with short labels (no color legend); the comfort bounds sit compactly inline on the temperature row (56 px inputs).
• The space dialog is wider (500 px) — the settings no longer feel cramped.

v1.15.0 — 2026-07-06 (temperature room fill)

• New room fill mode "Temperature": light blue below the comfort range, green inside it, warm yellow above. The comfort bounds (default 20–25 °C) are editable right in the space dialog and appear only when the mode is selected; bounds entered in the wrong order are swapped automatically. A room's temperature is the average of its devices' temperature readings; rooms without a reading stay unfilled. (+areaTemp helper, 3 new frontend tests, backend schema fields.)

v1.14.0 — 2026-07-06 (per-space display settings, hand-drawn spaces, testing checklist)

• Per-space "Display" settings (space dialog): always-visible room borders, room name labels, a border/name color picker with an opacity slider, and a room fill mode — none / by zigbee signal (red→green) / by lights (yellow = something is on, grey = all lights off; rooms without lights stay unfilled).
• Room name labels are draggable like device icons; positions persist server-side (layout keys rl_<roomId>), defaults to the room centre; hidden in markup mode.
• Hand-drawn spaces: the space dialog got a "No image — I'll outline rooms by hand" option with a canvas orientation choice (landscape/portrait/square). Such spaces default to visible borders and names; switching an existing space to this mode detaches its background image. The plan image is no longer mandatory.
• Backend: explicit validation schema for the new per-space settings (+test).
• demo/ harness moved into the repository (synthetic home, host page, capture and smoke scripts, icon-map generator) — public materials and smoke tests no longer depend on a perishable sandbox.
• docs/TESTING.md: a comprehensive manual-testing checklist (environments matrix, every feature, edge cases); policy — updated in the same commit as any functional change. The first self-run found and fixed two bugs: plan_url not detached on image→draw switch, and a _stateClass crash on state objects without entity_id.
• Tests: 43 frontend + 11 pure backend; new smokes smoke_space_settings and smoke_edge_cases (empty install, XSS names, legacy layout entries, 150-device perf).

v1.13.3 — 2026-07-06 (privacy: drop legacy real-house plan sources)

• Removed the legacy assets/ directory (real floor-plan sources from the pre-v1.3 bundled-data era). Nothing in the build referenced it; instance data lives in server-side config. Note: the files remain in old git history and release archives.

v1.13.2 — 2026-07-05 (audit round 3: fixes + buildDevices test suite)

• buildDevices finally has a direct unit-test suite (12 tests on a fake hass): area filtering, curation incl. show-all, duplicate numbering, light-group folding and its group_lights=false inverse, marker claim/metadata/hidden/virtual/entity paths, custom icon rules + the deliberate lock override, device_class fallback, primary-entity priority, LQI/temperature extraction. Frontend tests: 28 → 41.
• Fix: t() now substitutes every occurrence of a placeholder (extracted as the pure subst() helper with a regression test).
• Fix: _saveConfigNow refreshes the local config on a rev conflict before rethrowing — a retry no longer hits the same conflict (the debounced path already did this; the immediate path did not).
• Fix: pointercancel on a device icon clears the long-press timer — no phantom info card after an aborted touch gesture.
• Repairs check moved to repairs.py and now re-runs after every config save, so a missing/restored plan file is reflected in the Repairs UI without a restart.
• Documented the deliberate mdi:lock override in devices.ts (wins over custom rules — a mislabeled lock icon is safety-relevant confusion).
• Test infra: tsconfig.test.json also compiles devices.ts/types.ts; scripts/fix-test-build.mjs appends .js to tsc's extensionless ESM imports.

v1.13.1 — 2026-07-05 (distribution materials)

• Demo GIF in the README — recorded on a fully synthetic demo home (no real floor plans): live states, tap-to-toggle, drag, zoom, info card, space tabs.
• GitHub issue templates (bug report with diagnostics hint, feature request), CONTRIBUTING.md (5-minute setup, ground rules, architecture pointers), Discussions enabled.

v1.13.0 — 2026-07-05 (universality: floors import, icon rules, tap actions)

• Floors import wizard: on first run, if the HA registry has floors, the card offers to create a space per floor — names prefilled, the (mandatory) plan image is requested step by step, any floor can be skipped; after the last one the room-markup mode opens automatically. No floors / old HA → the old single-dialog onboarding.
• Editable icon rules: the built-in "name pattern → MDI icon" rules are now data (settings.icon_rules) with an in-card editor (⬡ in the header): reorder, delete, add, live test field, invalid-regex highlighting, one-click reset to the bilingual (EN/RU) defaults. Fallback chain: rules → entity device_class → generic chip. Invalid user regexes are skipped safely.
• Tap actions: tap_action card option (info default | more-info | toggle) plus a per-device override in the device dialog. Safety model: a card-wide toggle only affects lights/switches/fans/humidifiers; covers/valves need a conscious per-device toggle; locks and alarm panels never toggle from the plan. A long press (600 ms) always opens the info card.
• i18n dictionaries moved to JSON (src/i18n/{en,ru}.json) — new languages can be contributed without touching TypeScript; tests enforce key and placeholder parity.
• Light-theme pass: hardcoded dark badge backgrounds replaced with theme variables.
• Tests: 28 frontend (was 15) — tap-action resolver incl. security cases, icon-rule compilation/overrides/device-class fallback, floors sorting, i18n parity.

v1.12.0 — 2026-07-05 (Quality Scale: Bronze + selected Silver/Gold)

Backend brought to Integration Quality Scale patterns (custom integrations are not formally graded; progress is tracked in custom_components/houseplan/quality_scale.yaml):

• entry.runtime_data (typed HouseplanData: both stores + the write lock) replaces hass.data[DOMAIN] for entry data; WS handlers resolve it per call and answer not_ready while no entry is loaded. New store.py common module.
• test-before-setup: storage readability is verified in async_setup_entry (ConfigEntryNotReady on failure). Unloading is supported; WS commands and static paths are global by design (documented).
• single_config_entry: true in the manifest replaces the manual flow check.
• Store versioning: stores now carry minor_version and a migration hook (HouseplanStore._async_migrate_func) — schema changes get a single upgrade path.
• Diagnostics (diagnostics.py): redacted dump (options, rev, per-space stats, markers with personal fields redacted, layout size).
• Repairs: a missing plan file raises a repair issue (broken_plan) with en/ru translations; issues clear automatically when resolved.
• System health (system_health.py): rev, spaces/rooms/markers/layout counters.
• Uninstall cleanup: async_remove_entry deletes our Lovelace resource entry.
• Tests: config flow, WS API (layout ops, rev conflict, not_ready, plan upload validation), HTTP upload (ok/bad ext/traversal) on pytest-homeassistant-custom-component — run in CI on Python 3.13; pure validation tests still run anywhere.
• strings.json added; translations updated.

v1.11.2 — 2026-07-05 (device dialog: usable Description height)

• The Description textarea in the device edit dialog was squeezed to ~2 lines by the dialog body's flex column. Now min-height: 92px, flex-shrink: 0, rows=4; still resizable vertically.

v1.11.1 — 2026-07-05 (brand images shipped inside the integration)

• Brand icon and logo (256/512, transparent background) now live in custom_components/houseplan/brand/ — the native mechanism for custom integrations since Home Assistant 2026.3 (served via /api/brands/..., local images take priority over the brands CDN). The former root brand/ directory is gone, and no home-assistant/brands PR is needed (theirs bot closes such PRs as obsolete).

v1.11.0 — 2026-07-05 (full English translation + UI localization)

• UI localization (en/ru): every card string moved to src/i18n.ts dictionaries. The language follows the HA user profile (hass.locale) automatically; a new language: en|ru card option forces it. The GUI editor got the option and its own localized labels. Generated device names (light group, unnamed, virtual device) are localized via a loc callback in BuildCtx.
• English-only codebase: all comments, docstrings, section banners, JSDoc, test names, backend WS/HTTP error messages and log lines translated to English. Russian remains only where it is functional or content: the ru i18n dictionary, translations/ru.json (config flow), iconFor regex patterns matching Russian device names (with their test fixtures), and the Russian documentation copy.
• Docs: README is now English-first with a full Russian copy in README.ru.md; docs/ARCHITECTURE.md, DEVELOPMENT.md, ROADMAP.md and the entire CHANGELOG history translated to English. translations/en.json had Russian strings — fixed.
• Removed obsolete RELEASE_NOTES_v1.9.3.md and scripts_publish.sh (publication is done; the repo lives at github.com/Matysh/houseplan-card).

v1.10.0 — 2026-07-05 (audit: write races, XSS, modularity)

Backend

• Write race eliminated: all load→modify→save cycles (layout/set|update|delete, config/set) are serialized by a shared asyncio.Lock — concurrent WS calls no longer lose changes, and the expected_rev check became atomic.
• New WS command houseplan/layout/delete — cleans up a position when a marker is deleted (previously orphans accumulated in .storage/houseplan.layout).
• Removed the dead WS command houseplan/file/set — files are uploaded over HTTP only (/api/houseplan/upload), as the card already did.
• HTTP upload: the 25 MB limit is enforced WHILE reading the multipart stream (abort at the limit), not after reading the whole file into memory; file stat() moved into the executor.
• request.app[KEY_HASS] instead of the deprecated request.app["hass"] (with a fallback for older HA).

Frontend

• The god-component was broken up: houseplan-card.ts 3023 → ~1990 lines. Styles → styles.ts; types → types.ts; building devices from the HA registries (curation, light groups, markers, LQI/temperature) → devices.ts (pure functions).
• Last-writer-wins in the layout eliminated: _saveMarker writes the position pointwise (layout/update), not the whole layout (layout/set) — it no longer wipes positions from other windows (the regression class of the v1.4.4 incident). Rebinding/deletion clean up the old position.
• XSS closed: marker link and pdfs[].url go through safeUrl() (only http(s) and relative paths; javascript:/data: are rejected). +12 tests.
• File uploads via hass.fetchWithAuth (auto-refresh of an expired token), fallback to the raw token.
• The dacha hardcode removed from the GUI editor: the "default space" list is built from the server config (WS config/get), not the baked-in f1/f2/yard.
• rules.ts: removed the dead export GROUP_TITLES; the iconFor regexes are precompiled.
• A single _errText() in all error handlers (never "[object Object]").

v1.9.3 — 2026-07-05 (audit + refactoring + tests)

• The pure functions fitView (viewport contain rectangle) and declump (icon push-apart) were extracted from the card into logic.ts — covered by unit tests (was 9 → now 14 tests).
• _lqiFor and _roomLqi now use the shared averageLqi (duplicate averaging removed).
• Removed dead code left after dropping the separate edit mode: the _edit field (written but never read), the methods _renderEditbar and _applyXY (never called).
• No behavior change — only structure and test coverage. Verified: tsc, build, 14 frontend tests + 10 backend tests green, headless smoke test (render/zoom/devices/declump) clean.

v1.9.2 — 2026-07-05 (grid twice as fine)

• The markup/snapping grid step was halved: GRID_N 120 → 240. Device positions and room outlines are NOT recomputed and do not shift: coordinates are stored as normalized fractions and snap to grid nodes, and the old nodes (multiples of 1/120) are an exact subset of the new ones (multiples of 1/240). Verified on the live layout (65 positions — all already on the new grid). Dragging now allows more precise positioning.

v1.9.1 — 2026-07-05 (Zigbee signal: reading from the attribute + ZHA)

• The signal level is now taken not only from the dedicated *_linkquality sensor (Z2M), but also: from *_lqi sensors (ZHA), and from the linkquality/lqi ATTRIBUTE on any entity of the device. This covers devices whose dedicated signal sensor is disabled but the value is available in an attribute.
• NOTE: if a device's *_linkquality sensor is disabled (disabled_by=integration) AND the value is not published anywhere as an attribute — the signal cannot be shown; enable the sensor in the HA registry.

v1.9.0 — 2026-07-05 (UX: always-on dragging, declumping, show all, responsive)

• Icon dragging is available at all times — the separate "edit mode" is gone (the ✥ button removed). Clicking an icon opens the device card (metadata editing — via the "Edit" button inside it), dragging works at any moment. _pointerDown no longer requires _edit.
• Icons no longer clump together (_declump): after the automatic grid layout a push-apart pass runs within the room so that icons do not overlap each other.
• Positions are pinned when a room is saved: the auto-positions of the area's devices are written into the layout once, so icons do not get reshuffled when the order in the HA registry changes.
• Duplicates are numbered instead of hidden: devices with the same "name|area" get a suffix (" 2", " 3"…) instead of silently disappearing.
• The 👁 "Show all devices" button in the header: temporarily disables curation and shows all devices of the area (bridges, service records, duplicates) — in case a needed one is hidden. The show_all flag in the config settings.
• Markup continuation hint: after saving a room a toast shows the room counter and suggests outlining the next one or leaving markup mode.
• Responsive header: the toolbar wraps and shrinks on narrow screens (media query ≤620px).

v1.8.4 — 2026-07-04 (onboarding: required fields + user guidance)

• Initial setup brought to the target scenario: install → space dialog → rooms → auto device icons.
• The background is mandatory when creating a space: "Save" stays disabled without an uploaded plan (previously only the name was required — an empty space could be created).
• The room area is mandatory, with an explicit escape hatch: the main "Save" requires binding to an HA area; for decorative rooms without devices (hall, sauna) there is a separate "No area" button (only a name is needed). Previously saving was possible with "name OR area".
• User guidance: with an empty server config the space dialog opens automatically; after the first space is added the card enters room markup mode by itself with an "outline the rooms" hint.
• When a room with an area is saved, the icons of that area's devices are auto-placed inside the outline (the curated set: without bridges/service records/duplicates/individual lamps from groups), and a toast shows how many devices were added.

v1.8.3 — 2026-07-04 (instant start: config cache, data in the background)

• Icons and the plan appeared with a delay — the card waited for the server response (WS config/get
  • connection warm-up retries), and until then the space model was empty.
• A "stale-while-revalidate" cache was introduced: a snapshot of the server config + rev + layout is saved in localStorage['houseplan_card_cfg_v1']. In setConfig (synchronously, before hass arrives) it is restored — the plan and icons are drawn immediately from the cache (verified: setConfig populates the model in 0.2 ms without the server), while fresh data loads in the background and updates the card. Live states/temperatures/signal come in as hass warms up.
• The cache is refreshed after every successful load, live resync and icon position save, so on the next open the current snapshot is visible. When the server is unavailable the last known plan is shown instead of the empty onboarding.

v1.8.2 — 2026-07-04 (vector-crisp zoom via viewBox + full-width stage)

• Zoom moved from CSS transform: scale() to manipulating the SVG viewBox. Previously the layer was rasterized and then scaled — everything "blurred" when zooming in. Now the browser redraws the vector at the target resolution: icons, room labels, lines, hatching and the vector background remain crisp at any scale (verified at 274%).
• The icon layer (HTML) is positioned and scaled by the same view, not a global transform — the icons are crisp and grow together with the plan.
• The stage now occupies the full viewport width (a "contain" model by the stage aspect): when zoomed in the content fills the width without black bars on the sides. Fully zoomed out the whole plan is visible (both width and height), the margins around it are filled with the card background, not black.
• All coordinate math (markup click _svgPoint, icon drag, pan, pinch) was rewritten in unified view coordinates — editing is correct at any zoom. A ResizeObserver on the stage recomputes the view when dimensions change (sidebar, rotation). Pan/zoom are constrained to fit.

v1.8.1 — 2026-07-04 (fit-to-viewport + per-space zoom persistence)

• Zooming out to the full view: the lower zoom limit = 100% coincides with the fully visible plan. .stage is now constrained by the viewport height (width:min(100%, calc((100dvh − 118px) × aspect)), max-width:100%, centering), so on reset/zoom-out the whole layout is visible both in width and height without clipping.
• The zoom level is remembered per space and locally per device (localStorage['houseplan_card_zoom_v1'], _zoomBySpace): switching floors restores each floor's zoom; on return the pan is centered and constrained.
• Verified on live HA: f1→196%, f2→140%, the yard untouched — after switching around the values are restored; reset gives 100% and the full plan (874≤992 px in height).

v1.8.0 — 2026-07-04 (plan zooming)

• Zoom and pan of the layout: mouse wheel (towards the cursor), two-finger pinch on a touch screen, one-finger background drag when zoomed in, −/reset/+ buttons in the toolbar, a zoom badge.
• Implemented via a CSS transform on .zoomwrap (translate+scale); the coordinate math (markup clicks, icon drag, tooltips) was recomputed with zoom/pan in mind — editing works when zoomed in too. Pan is constrained so the content always covers the stage. Zoom 100–800%.
• .stage: overflow hidden + touch-action none (custom gestures instead of the browser's).

v1.7.4 — 2026-07-04 (PDF over HTTP instead of WebSocket)

• THE ROOT CAUSE of being unable to upload a PDF: the file was sent as base64 in a single WebSocket message, and WS has a message-size limit — a real manual (>2–3 MB) exceeded it, the connection dropped ("Connection lost"), which both failed the upload and closed the dialog (WS drop → reconnect → re-render). Confirmed by test: 1 MB over WS is fine, 3 MB → Connection lost.
• Manual files are now uploaded through the HTTP endpoint POST /api/houseplan/upload (multipart, HomeAssistantView, requires_auth, admin_only check) — like media in HA itself. Verified: 3 MB (182 ms) and 10 MB (446 ms) upload without a hitch.
• Readable errors everywhere (_errText): no more "[object Object]"; clear texts for too_large / bad_ext / unauthorized.
• The WS command houseplan/file/set is kept for compatibility, but the frontend uses HTTP.

v1.7.3 — 2026-07-04 (device dialog fixes)

• PDF manuals failed to upload: the manual base64 (btoa(String.fromCharCode(...subarray))) crashed on real files (RangeError when spreading large arrays), and when the dialog was closed during an await it threw a null access. Replaced with FileReader.readAsDataURL (reliable for any size); the results are accumulated and added only if the dialog is still open (no exceptions).
• The device/space/room edit dialog closed on an outside click and "by itself" (an accidental click on the background overlay, including after closing the system file picker). Removed background-click closing for editor dialogs — only explicit Cancel/Save/Esc. The info card (read-only) still closes on an outside click.
• Verified on live HA: PDFs attach; a background click and dialog data refresh do not close the dialog.

v1.7.2 — 2026-07-04 (fix for the mobile "configuration error")

• THE CAUSE: the card was hooked up only via add_extra_js_url (extra_module_url), whose loading the frontend does NOT wait for — on a cold start of the mobile app the dashboard was drawn before the element was registered → "configuration error". (All working HACS cards are Lovelace resources.)
• FIX 1: the integration registers the card as a Lovelace resource (module) — the frontend waits for those before rendering. Idempotent (updates the URL on a version change, no duplicates); a fallback to extra_module_url for Lovelace YAML mode. _register_lovelace_resource in __init__.py.
• FIX 2: _loadFromServer retries (up to 8 attempts on hass updates) — if hass arrived before WS readiness, the card does not get stuck on the onboarding but waits for the config.
• Verified: the houseplan-card.js resource is registered, extra_module_url is empty (a single clean module), the card renders the plan on a fresh tab without the error.

v1.7.0 — 2026-07-04 (audit + refactoring + tests)

• Removed the sample house baked into the bundle (the dacha, ~245 KB of base64 plans + ROOMS/FLOOR_*): the bundle went 293 KB → 83 KB. A fresh install shows the "Add a space" onboarding, not someone else's house.
• Removed the legacy→server migration code (the dacha is already on the server config) and the dead device_overrides/virtual_devices paths (replaced by markers[]).
• Pure logic extracted into src/logic.ts (lqiColor, snapToGrid, segKey, pointInPolygon, markerIdForBinding, averageLqi) — covered by unit tests (node:test, 9 tests + iconFor).
• Backend: validation/sanitizers extracted into validation.py (no HA imports) — pytest, 10 tests.
• SECURITY: a test revealed that the file/marker name sanitizer preserved leading dots (a directory traversal risk via ".."); leading-dot stripping added, empty → misc/file.
• Fixed real bugs previously masked by the truncated rules.ts: DOMAIN_PRIORITY was cut short (breaking the more-info entity selection); _defaultPositions crashed on polygon rooms (now bbox). tsc --noEmit added to the build and CI — strict typing passes.
• Removed the junk duplicates src/data/{editor,rules}.ts; versions synchronized (the manifest was stuck at 1.4.0).
• CI: added typecheck, frontend and backend unit tests.

v1.6.2 — 2026-07-04

• The "Room" field in the device dialog is now for ALL icons (not only virtual ones): for bound ones it "overrides the placement" (by default, the device's area); changing the room moves the icon to its center. Stored in marker.space/area and wins over the HA area.
• An "Edit" button was added to the info card — it opens the device edit dialog.

v1.6.0 — 2026-07-04 (Phase 3: device editor)

• The "markers" model (config.markers[]): a hybrid — auto-discovered HA devices appear by themselves, markers edit/rebind/augment them and describe manual/virtual icons. The marker id preserves the position (device→device_id, entity→lg_, virtual→v_).
• Clicking an icon: normal mode → the info card (name, model, state, link, description, PDF manuals, an "Open in HA" button); edit mode → the edit dialog.
• The device dialog: name, binding (a picker of all HA+Z2M devices/groups+helpers with a text filter, minus already-placed ones and duplicates by name|area, plus "Virtual device"), MDI icon (ha-icon-picker), model, link, description, manual file attachment (PDF to the server), room (for virtual ones), Remove/Cancel/Save.
• Toolbar: a "+" button (tooltip "Add device") — an empty dialog.
• Backend: MARKER_SCHEMA in the config; WS houseplan/file/set (files in /config/houseplan/files/, ≤25 MB, served from /houseplan_files/files/); the files static path registered.
• Virtual icons are now draggable and positioned like normal ones (layout by id).

v1.6.1 — 2026-07-04

• The binding picker hides device duplicates by "name|area" (Tuya/LocalTuya), same as the dedup on the plan.

v1.5.1 — 2026-07-04 (space management)

• A pencil icon to the right of each space name in the top toolbar + a "+" button (only with a server config).
• The space dialog: a "Name" field, a preview of the current background + "Upload/Replace…" (SVG/PNG/JPG/WebP, base64 → houseplan/plan/set, the aspect ratio is detected from the file), Delete / Cancel / Save buttons. Creating an empty space and deletion (together with all its rooms and markup, with a confirmation). Saved via config/set with a revision.

v1.5.0 — 2026-07-04 (light groups = entities)

• Lamps replaced by group entities: HA light groups (platform=group, area from the entity registry) and Z2M groups (device model=Group) are rendered with the mdi:lightbulb-group icon; a click → the group's more-info (controlling the whole group and its members natively in HA).
• Individual lamps are hidden in rooms that have a light group (settings.group_lights=false brings back the per-lamp mode).
• The old visual grouping and the custom member menu were removed (code simplification).
• The positions of the old groups (grp_) were migrated to the new ids (lg_<entity_id>) in the dacha layout.

v1.4.4 — 2026-07-04 (CRITICAL fix: configuration race)

• INCIDENT: the config was saved wholesale on a last-writer-wins basis — an open client with a stale copy wiped other clients' edits (the first iteration of the user's markup was lost).
• Fix: optimistic locking — the config carries a rev; config/set accepts expected_rev and returns a conflict error on mismatch; the client re-reads the config.
• Live synchronization: config/set broadcasts a houseplan_config_updated event; all open cards are subscribed and re-read the config automatically (windows no longer diverge).
• Positions during drag are saved pointwise via layout/update (dirty set), not a full layout/set — the layout is also no longer wiped between windows.
• A config backup before deployment: .storage/houseplan.config.bak-*.

v1.4.3 — 2026-07-04

• Device icons snap to the same grid as the markup (the icon center = a node, snapping on drag and on X/Y input). The existing 57 positions in the dacha DB were snapped to the nodes.

v1.4.2 — 2026-07-04 (markup grid)

• The grid step was halved: GRID_N 60 → 120 (step 8.33 render units ≈ 0.83% of the plan width).
• Grid points are rendered ON TOP of the plan and rooms (the grid-rect was moved from below the plan into the top markup layer); the points are higher-contrast (r=0.14g, outline).
• Dacha data: the boundaries of all 13 rooms were snapped to grid nodes (edge snapping, shifts ≤ half a step; only the instance config was edited via houseplan/config/set, the code was untouched).
• Card cache: the module URL ?v= is taken from const.VERSION — when updating the frontend, bump const.py and restart HA, otherwise browsers keep the old module in memory cache.

v1.4.1 — 2026-07-04 (markup UX)

• Esc / Ctrl+Z while drawing remove the last point (and its line, if it was added by that step; reused walls belonging to others are untouched).
• The editing panel (markup and layout editing) was moved to the top under the card header and pinned together with it (a shared sticky container .hdr).
• Closing the outline automatically opens the "New room" modal dialog: the display name, a dropdown of ONLY the free HA areas (not assigned to any room of the config), Save/Cancel. Cancel (or Esc) removes the closing point — the outline can be continued. Choosing an area with an empty name fills in the area's name.

v1.4.0 — 2026-07-04 (Phase 2: room markup editor)

• The "Markup" mode in the card (the mdi:vector-square-edit button, only with a server config): a grid of points (60 nodes across the width), lines drawn by pairs of clicks with node snapping, a polyline preview.
• A closed outline (a click on the first point) activates "Save": choosing an HA area from a dropdown + a name; the room is saved as a polygon (poly, normalized vertices).
• Tools: Add (drawing), Erase line (a click on a line), Delete room (a click inside + confirm). The "wall" lines are stored in space.segments and reused by neighboring rooms (shared walls — via clicks on existing nodes).
• Room rendering: polygons on par with rectangles (hover, click into the area, LQI tooltip, the label at the centroid); in markup mode the outlines and names of all rooms are visible.
• Backend: ROOM_SCHEMA accepts poly (≥3 vertices) or x/y/w/h; SPACE_SCHEMA — segments.

v1.3.0 — 2026-07-04 (Phase 1: server-side configuration)

• The houseplan.config Store: spaces (plan, aspect, view_box, rooms), device_overrides (hidden/icon/name), virtual_devices, settings (exclude_integrations, group_lights).
• WS: houseplan/config/get|set, houseplan/plan/set (plan file upload as base64 → <config>/houseplan/plans/, served through /houseplan_files/plans/).
• The card: a resolve model — the server config (coordinates NORMALIZED 0..1, render 1000×1000/aspect) or the legacy bundle (canvas 1489×1053). Layout v2: {device_id: {s, x, y}} normalized.
• The "To server" button in edit mode — a one-click migration of the legacy config (plans, rooms, view_box, layout). Performed at the dacha: .storage/houseplan.config + plans/f1.svg,f2.svg.
• Read-side support for device overrides and virtual devices (the management UI — phases 3–4).

v1.2.2 — 2026-07-04

• The card toolbar (floor tabs) pins under the HA header while scrolling (position: sticky; top: var(--header-height); ha-card overflow: visible).
• Incident: an intermediate build on the unstable mount produced a broken bundle that crashed the dashboard rendering; the rule "build only in /tmp + md5 control" was locked into DEVELOPMENT.md.

v1.2.1 — 2026-07-04

• Icons no longer enlarge on hover/drag (transform: scale removed).

v1.2.0 — 2026-07-03

• Room boundaries snapped to the walls of the vector plan.
• Zigbee LQI: the value under the icon, the room average in the tooltip, a red→green gradient, the show_signal option.
• mdi:lock for any devices with a lock.* entity (TTLock).
• The hallway switch: the device's area in the HA registry was fixed (it was in detskaia_elina).

v1.1.0 — 2026-07-03

• Vector backgrounds (SVG from REMPLANNER), automatic scale/offset alignment via raster correlation.
• Icon size as a % of the plan width (container queries, default 2.5%).

v1.0.1 — 2026-07-03

• fix: nested SVG fragments via lit svg`` (the background/rooms were not rendered).
• fix: the version taken from const instead of a blocking manifest.json read in the event loop.

v1.0.0 — 2026-07-03

• First release: the Lovelace card (TS+Lit, no token, driven by hass) + the houseplan integration (WS layout storage, JS serving). The prototype's model carried over: curation, lamp groups, iconFor, temperature, more-info, area navigation, drag layout.
