houseplan-card/docs/CHANGELOG.md

Changelog

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.
