House Plan — complete user guide

Current for v1.64.0. This guide describes the interface implemented by the current source. Русская версия.

House Plan installs two Lovelace cards together:

• custom:houseplan-card — the live plan, editors, state and actions;
• custom:houseplan-space-card — an inert rendering of one space with a link to the full plan.

Configuration, uploaded files and shared positions stay inside Home Assistant. Only the explicit Help & feedback action can contact the House Plan support relay, and exact plan geometry is attached only after you opt in and preview it.

Input support. View and kiosk are supported on phones, tablets and wall touch panels. Create and maintain a plan on a desktop browser with a mouse and keyboard. Touch editing is best effort: an operation may be awkward, limited or absent, but it must not corrupt data or trigger an accidental Home Assistant action. The authority is TOUCH-SUPPORT.md.

1. Data model and terms

Settings form a hierarchy. Global settings provide defaults; a space may override them; a room may override its space; a marker may override its room.

Level	Meaning	Stored data
Card	One dashboard instance	Initial space, language, icon size, value/LQI display, live state, kiosk and cycle
Global settings	Defaults for all spaces	Fill palette, background, Glow radius, north, sun, room-hover information and icon rules
Space	Floor, yard, garage or building	Plan image, scale, rooms, walls, openings, decor and display settings
Room	A closed outline	Name, optional HA area, temperature/humidity source and local fill
Wall	A room-contour or independent segment	Stable identity and thickness from 0 to 100 cm; zero-thickness appearance is selected per space
Opening	Door, window or gate on a wall	Size, orientation, contact and optional lock
Marker	A device shown on the plan	HA binding, room, action, presentation, light role and attachments
Background item	Visual context	Line, shape, text, furniture or plan-image transform

A room is the spatial unit that owns area and an optional HA area. A partition or column affects the physical rendering and light but does not create a room.

2. Installation and access

Requirements

Component	Requirement
Home Assistant	2024.6.0 or newer
Installation	Any installation that supports custom integrations
Browser	Web Components, SVG and Pointer Events
Editing permission	Administrators by default

HACS

1. Search for House Plan in HACS and install it — the integration is in the HACS default catalog, no custom repository needed.
2. Restart Home Assistant.
3. Open Settings → Devices & services → Add integration → House Plan.
4. Keep “administrators only” enabled unless other users must edit the plan.

The integration registers its Lovelace resource automatically. After installing or updating House Plan, restart Home Assistant and fully reload the page: Ctrl+F5 on Windows/Linux or Cmd+Shift+R on macOS.

Storage mode (Home Assistant default)

No YAML is normally needed. If automatic registration did not make the card available, open Settings → Dashboards → menu ⋮ → Resources → Add resource, enter /houseplan_files/houseplan-card.js, and select JavaScript module.

YAML resources mode (Home Assistant 2026.2+)

To manage resources in configuration.yaml independently of the dashboard mode, use:

lovelace:
  resource_mode: yaml
  resources:
    - url: /houseplan_files/houseplan-card.js
      type: module

Legacy Home Assistant 2024.6–2026.1

Only for a full-YAML dashboard that is already managed in YAML, use:

lovelace:
  mode: yaml
  resources:
    - url: /houseplan_files/houseplan-card.js
      type: module

mode: yaml changes the dashboard itself to YAML mode. Do not switch a storage dashboard to legacy YAML just for House Plan; use the Storage mode instructions above instead. Do not use /custom_components/houseplan/frontend/houseplan-card.js; it is an on-disk path, not the JavaScript URL served by Home Assistant.

Manual installation

Copy the release folder to config/custom_components/houseplan, restart Home Assistant, and add the integration. If the card is still unavailable, follow the Storage or YAML resource instructions above for your Home Assistant version and resource mode. Always copy the complete integration folder: the stable resource URL remains one file, but that entry loads internal content-hashed modules. A lone houseplan-card.js is not a supported install.

The ordinary View does not download editor code. The first opening of Plan, Device or Background may therefore take a brief moment. If that internal module cannot be loaded after one retry, the plan stays in View; no half-open editor is kept. After a network failure the card invites you to check the connection and press again — the next press starts a fresh download. Only when the tab holds code from another build does the advice ask for a page refresh instead. A fully stale proxy-cached houseplan-card.js no longer leaves an empty card after an update: it shows a panel asking to reload the page.

Permissions

Every signed-in user can view the plan. Home Assistant permissions still govern device service calls. With the default integration option, only administrators can edit configuration or upload files. Plan optimization and its undo always require an administrator.

3. Adding a card

Minimal configuration:

type: custom:houseplan-card
title: House plan

Field	Default	Purpose
title	empty	Card title
default_floor	first/last opened	Initial/fallback space for an unpinned card
floor	not pinned	Keep this card on one stable space ID or zero-based YAML index
language	HA language	auto, en, ru or de
icon_size	2.5	Base marker size, 1–6% of plan width
show_temperature	true	Compact temperature and humidity values
live_states	true	Work/open/unavailable presentation and activity; alarms remain visible
show_signal	true	Base LQI display, overridable by a space
kiosk	false	Full plan without editors or header
cycle	0	Kiosk auto-cycle interval in seconds; 0 disables it

The legacy card-level tap_action is ignored. Each marker owns its action.

auto recognizes the primary Home Assistant locale: de, de-DE, de-AT and de-CH use German, while fr, fr-FR, fr-CA, fr-BE and fr-CH use French (a community translation — thank you, @OUARZA). Lazy dictionaries (German, French) are downloaded once on first use and shared by all House Plan cards on the page. Until it is ready, a neutral busy surface is shown instead of briefly flashing English; if both bounded download attempts fail, the card becomes usable in English and says so with a "Could not load the language pack" toast.

4. Quick start

Use this order for a first working room:

1. Add a space with +, or import Home Assistant floors.
2. Upload SVG/PNG/JPG/WebP, reuse an uploaded plan, or choose no image.
3. Set the real size of a grid cell. It controls wall, opening, furniture and area measurements.
4. In Plan choose Walls, draw the boundary, then click its first point to close the first room face.
5. Name the room and bind it to an HA area, or use No area.
6. Add wall thickness and openings if needed.
7. In Device, position auto-discovered markers and choose their actions.
8. In Background, align the plan image and add labels, lines or furniture.
9. Return to View and confirm live values and actions.

Do all plan creation on desktop. Phone, tablet and wall-panel View remain full product surfaces after setup.

5. Interface modes

View is the state with no editor open. Close the active editor to return to it.

Mode	Devices	Geometry	Background/openings
View	Live and actionable	Read-only; room hover shows summary	Visible according to space settings
Plan	Hidden	Rooms, walls, columns and openings editable	Openings always visible
Device	Draggable; click opens settings	Read-only background	Read-only background
Background	Dimmed and inert	Dimmed	Background objects editable
Kiosk	Actionable as in View	Read-only	Read-only; no editors
Static card	Not live or interactive	Render only	Render only

The room highlight remains available in View and kiosk. To keep that highlight but hide the floating room summary, turn off General settings → Show the room information window on hover. The option is on by default and does not affect device tooltips.

For an occasional Zigbee placement check, an administrator can enable General settings → Show Zigbee links when hovering over a device. The option is off by default. Load the provider snapshot there: Read ZHA data reads ZHA's existing cache, while Update map starts an explicit Zigbee2MQTT raw network-map scan for each entered base topic (default zigbee2mqtt). The latter may take 10 seconds to 2 minutes and can temporarily slow the Zigbee network.

After data is loaded, moving a real mouse over a mapped Zigbee marker shows only its observed direct neighbours. Links to markers on the current space are lines; drawable neighbours on other spaces are summarized as a temporary count. An arrow on a line shows the next step towards the coordinator: an ordinary device points to its parent, while arrows pointing into a router show devices whose path goes through it. Neighbour links outside the derived path tree remain plain lines.

The active diagnostic layer is deliberately drawn above room names and devices that are not part of the shown link, so a busy plan cannot hide the route. The complete source and locally connected device markers remain above the lines. An unknown-quality gray dashed link has a thin dark outline for contrast; this does not change its meaning. The whole layer is pointer-transparent, so device and room actions continue to work normally.

If the next step is in another space, a short bubble names that space. If the needed router or coordinator is not placed on the plan, the bubble says so. If the snapshot has no coordinator or the graph is disconnected, House Plan does not invent a direction and leaves the link without an arrow. This is a stable path approximation derived from the neighbour snapshot, not the route used by every current packet. The layer does not appear on touch/pen, in kiosk, in editors or in the static card, and hovering never starts a scan.

Each editor has a stable primary toolbar. Tool parameters and selected-object actions appear in a context tray over the top of the canvas. On a narrow screen the tray scrolls horizontally instead of shrinking the plan.

Where an editor offers a color sample, one click opens the House Plan color picker. Hue, saturation, brightness, an exact HEX value and opacity (when the setting supports it) are available together; there is no second browser color dialog. The Hue track shows the full colour spectrum at a glance, with a contrasting ring keeping its slider visible. Changes remain a draft until the owning properties dialog is saved.

This is the same control everywhere: decor and custom fills, the global light/temperature/LQI/Glow/wall palettes, global and per-space backgrounds, room colour, marker Glow and the device activity ripple. Settings that already have opacity show it in the picker; colour-only settings do not acquire one. Default and Inherited background actions remain beside the colour sample and do not save the displayed fallback unless a colour is changed.

6. Navigation, zoom and input

The canvas grows with actual content. Fit all frames rooms and any distant objects; each space keeps its local View viewport.

Scenario	Mouse	Touch View	Touch editors	Keyboard
Zoom and pan	Wheel; drag empty space; −/+; double-click free background to Fit all	Pinch; drag; double-tap free background to Fit all	Available but precision is not guaranteed; no Fit-all double-tap	—
Room	A clean click fits the room with 10% margins	One tap fits the room; repeated room taps never become Fit all	—	Enter/Space on a visible room label
Change space	Click a tab	Tap; kiosk swipe at 1:1	Tap a tab	—
Device	Click/double-click per mode	Tap; safe actions equal desktop	Drag/properties are best effort	Esc closes the top surface
Walls drawing or precise drag	Full contract	Not applicable	Best effort; use desktop for Resize and exact nodes	Shift changes magnet/angle; Esc finishes a Walls chain or cancels the current precise drag
Editor history	Undo/Redo controls	Not applicable	Controls may work; no gesture guarantee	Ctrl/Cmd+Z, Ctrl/Cmd+Shift+Z, Ctrl+Y
Kiosk sizing	—	Hold empty space for 3 seconds	—	—

At zoom above 1:1 a horizontal kiosk gesture pans instead of changing space. Any manual kiosk operation pauses auto-cycle for 60 seconds.

Wheel, −/+, Fit all, the return arrow and a free-background double-click/tap in View or kiosk use a short smooth camera transition. Rapid wheel input changes the current destination instead of building a queue. Pinch and pan stay directly under the fingers. With the operating system's reduced-motion preference enabled, every zoom command is immediate.

Cancel and undo

• Esc finishes an active Walls chain without deleting its accepted segments. In Split and other tools it cancels the unfinished path, current drag/resize/rotation, or the top dialog without undoing an already committed action.
• Ctrl/Cmd+Z undoes an editor command; redo is Ctrl/Cmd+Shift+Z or Ctrl+Y.
• Undo/Redo stores up to 50 named commands for Plan and Background.

7. Spaces

A space may represent a floor, garden, garage or separate structure. It stores its image, grid scale, geometry, Background layer and display overrides.

Plan source

• upload SVG, PNG, JPG or WebP; Very large rasters (roughly 32 megapixels and up) are recognised from the file header before anything heavy happens: a dialog shows the exact resolution and memory numbers and offers a safe reduced copy. Your original file is never modified and the current plan stays untouched in every outcome. Images wider than 16384 px per side cannot be displayed by browsers at all — reduce those on a desktop first. SVG uploads as-is and is never rasterised.
• select a previously uploaded plan;
• choose no image and draw the geometry by hand.

The plan image keeps its proportions initially. Background can later move, scale or rotate it. Detaching a plan never deletes its server file; deletion requires an explicit user action.

Grid scale

The scale field is the real size of one grid cell. A new metric space starts at 1 cm per cell; with an imperial Home Assistant unit system it starts at 1 in per cell and the field is shown in inches. Floor import uses the same default for every new space.

Choose a finer cell when you need more precise snap points. It changes only the number of grid points per metre, not how the finished plan looks: physically equal rooms, walls, openings, labels and markers retain the same appearance. Existing spaces keep their stored scale. A legacy space without a scale still uses the 5 cm compatibility fallback and is not silently migrated.

Tab order

Space tabs follow the order in which the spaces were created, and that order can be changed: in any editor mode, grab a tab with the mouse and drag it to a new position. The new order is saved immediately and applies everywhere — the tabs, the kiosk swipe between floors and the carousel arrows. While dragging, a thin divider shows the exact insertion side; release outside the tab strip to keep the existing order.

Dragging works with a mouse and in the editors only. In ordinary View and on touch screens a tab still does one thing: it switches the space. There it is the primary way to navigate, and a gesture must not compete with a plain tap. Order is changed on a computer, like the rest of the plan work.

If a card anywhere pins its floor by number (floor: 0), remember that the number means a position: after a reorder such a card shows a different floor. The card warns about this once. Pin the floor by space id instead of a number to avoid it entirely.

Display settings

A space can show/hide room borders, names, LQI, Background and openings. It can override fill mode, Glow, day-cycle background, north, sun rays, room-card font scale and which room metrics are visible.

Room cards are positioned and scaled on the plan. View renders only the metrics enabled for that space.

In an existing space's settings, Copy creates a new space from its walls, openings, columns, Background objects, image transform, scale and display settings. The suggested name is the first free numbered copy, but duplicate names are allowed. Rooms and device placements are deliberately not copied; room walls become ordinary independent walls, ready for a different room layout. House Plan opens the accepted copy in Plan with Walls selected. If the saved plan must first be repaired, a separate warning explains that Optimize plans will change the whole plan; cancelling that warning writes nothing.

Deleting a space is blocked while any active device still points to the space, one of its rooms or a saved position on it, provided another space remains. Move or delete those devices first; then the confirmed delete removes the space-owned layout. The sole remaining space can still be deleted after confirmation: affected devices keep their bindings, icons, actions and settings but become unplaced. Plan images and attachments are not deleted automatically.

8. Rooms and walls

Create a room

Select Walls and draw one continuous chain. Every completed segment is saved immediately as an ordinary independent wall. Changing tool, editor, floor or leaving the card finishes the session-local chain: compatible straight sections become one wall and a proven duplicate over room masonry is absorbed immediately. Undo/Redo remains segment-by-segment but restores a canonical result, so a normal current-version chain leaves no work for Optimize plans. Reloading preserves the accepted walls but cannot finish the interrupted session. When the latest segment creates bounded endpoint/T/X faces, House Plan offers them from smallest to largest. Save creates that room and consumes exactly coincident chain walls, Keep as walls rejects only that candidate, and Cancel leaves all accepted walls in place with no partial rooms.

While drawing an open chain, Esc finishes all accepted segments as ordinary independent walls and keeps Walls selected; the next click starts a new chain. Ctrl/Cmd+Z instead removes the last accepted point and segment. Pan, pinch and pointercancel neither finish the chain nor add geometry.

Existing segment endpoints and lines appear above walls while drawing. An endpoint grows when the next click will join it. A point on a line shows where the click will create a valid junction.

A segment which is visually horizontal or vertical within 0.25° is stored as an exact axis: House Plan moves only the free endpoint, and preview already shows the final result. A real diagonal remains unchanged. Older invisible one-grid-step slopes are offered separately by Optimize plans, with the number of walls and maximum movement shown before confirmation.

Plan tools at a glance

Tool	Result	Room area	Light and shadow	Main limit
Walls	Continuous wall chain; offers rooms when it closes faces and finishes open chains as independent walls	Only a confirmed room has area	Positive thickness blocks light; zero thickness follows the space's dashed/solid policy	Partial room overlap is rejected; there is no separate Partition or Boundary drawing tool
Column	Square or circular support	Does not change area	Blocks light inside its shape	One shape/size/rotation; not a wall or room
Opening	Door, window or gate	Does not change area	Door/gate passage follows state; window may cast sun	Must fit completely on a suitable wall segment

Other operations edit existing geometry:

Operation	Result
Merge	Joins adjacent rooms; a dialog chooses the surviving identity, name and area
Split	Cuts a room from one wall to another; the larger part keeps the original room
Resize	Moves one eligible horizontal/vertical wall without changing room topology. Live labels report the two changing inner side-wall dimensions, highlight those walls, and place each affected room's area beside its side of the moving wall
Thickness	Changes one span or every wall of a room, including zero-thickness walls
Delete room	Deletes the room after choosing whether its exclusive physical walls remain; shared walls always remain

Deleting a room also clears that exact room from direct device assignments and vacuum segment maps, including maps owned by a vacuum on another floor. Merging rooms redirects the same references to the surviving room. The change is part of the room command: Undo and Redo restore or reapply geometry and references together without changing unrelated marker settings.

Wall thickness is stored in real units. A room may have different thicknesses on different spans. Open wall branches and T-junctions are allowed; shared geometry remains joined without painted end caps. At a saved T-junction both physical half-walls stay solid: the bounded bevel removes only an excessive projecting corner and never leaves a white triangular gap. A short arm stops at its real endpoint; the join repair never draws a cap, shadow or light barrier where no wall was saved. At junctions of three or more walls the removed bevel remains connected to the surrounding room/background rather than becoming a small enclosed hole. At a perpendicular T/X junction, the complete physical width of every participating wall remains solid through the node, including closely spaced neighbouring junctions. This is a rendering correction: a valid plan may remain unchanged when Optimize plans is run. Legacy near-axis walls are different: Optimize plans may explicitly straighten them, counts a shared wall once across both rooms and leaves an unsafe candidate unchanged. Cancel writes nothing and the confirmed batch has the normal one-deep Undo. Resize changes one room, or exactly two rooms when their shared wall coincides endpoint-to-endpoint. The wall stops at the first corner, opening, foreign room or other position that would change topology; no more than two rooms can change. It also stops where extending or shortening an adjacent wall would turn shared material into outer material (or the reverse), so one saved thickness never silently serves both roles. If neither direction has even one safe grid step, the handle explains that only part of a shared wall cannot be moved. Resize also preserves every unrelated wall exactly: changing the length of a neighbouring wall cannot shift a thickness boundary to an invented off-grid point. An ambiguous candidate is rejected instead of damaging another wall. Partial shared walls, diagonal walls and walls overlapped by an independent partition/column keep a dimmed handle with an explanatory tooltip and cannot start a drag. The former corner scale frame was removed. An ordinary opening on the moving wall follows it once; a side-wall opening stops the moving masonry at its physical jamb. Release creates one Undo step, while Esc or an interrupted pointer writes nothing.

A wall thickness of 0 cm is a real wall-axis record without a masonry body: it does not create hatch, wall area, an opening tunnel or a valid opening host. It is drawn and edited with the same Walls and Thickness tools as every other wall. In Space settings choose whether all zero-thickness walls are Dashed or Solid. Dashed zero walls let Glow and sun through; solid zero walls are zero-area light barriers. Missing settings use Dashed. Changing the style affects every 0 cm wall in that space; there is no separate Boundary tool or separate virtual-wall type.

During the drag, the moving wall itself has no redundant length badge. An outer wall shows one area badge; a shared wall shows two on opposite sides, each with a short leader. In a narrow room the area stays visible and may extend outside the room rather than overlap another area or the room-settings button.

Wall junction limits

To keep a plan physically meaningful, the editor refuses a write that would create an impossible junction. The thresholds are absolute — they do not scale with cell_cm:

Rule	Threshold
Angle between neighbouring walls of one node	at least 15°
Walls meeting in one node	at most 6
Wall length	at least 20 cm and never below its own thickness
Distance between non-incident nodes, and node to foreign wall	at least 5 cm
Room interior left after subtracting the masonry	at least 25 cm²

Length is measured along the WALL, not along a single contour piece: a short filler segment that compensates a thickness step is legal as long as the whole wall is longer than 20 cm. A T-joint (a wall end landing on the middle of another wall) is not forbidden by the distance rule.

If the check itself cannot run (an internal error), the change is not saved either — a "The junction check could not run" toast appears: the editor never waves a write through on faith.

The check runs on writes only. An already saved plan is never re-judged: migration, import and backup restore are never blocked, and an edit that does not touch the offending element passes as usual. The refusal appears where you work: drawing and Thickness leave the value unapplied and raise a toast naming the rule, while Resize stops the wall at the last allowed position and, once per gesture, names the rule the next step would break.

HA area binding

One HA area may be bound to one room. The binding drives automatic device placement, room LQI, light and aggregate climate. A real temperature or humidity sensor manually assigned to another House Plan room follows that placement for the automatic room average instead of remaining in its registry HA area. This also works for a room without an area; its manually assigned real sensors provide the automatic average, while an explicit room measurement source still takes priority.

9. Doors, windows, gates and locks

Choose Opening, select door/window/open passage/gate, and click a wall. Defaults are 90 cm, 120 cm, 90 cm and 300 cm. The complete opening must fit on the wall. Before the click, door, window and gate show their translucent architectural symbol. An open passage instead shows the exact future wall cut as a translucent wall-coloured segment with an orange boundary mark at each end. Its depth follows the real wall thickness; after saving it has no standalone symbol.

The placement preview also draws a thin dimension line from each jamb to the physical inner end of the wall. On a wall shared by two rooms, four values are shown — two along each room's inner face — because their usable boundaries can differ. On a finished independent wall, each value stops at the nearest physical face of a connected wall; where no such face exists, it keeps the distance to the independent wall's own endpoint. These richer dimensions apply only before a new opening is placed; dragging an existing opening retains its two established end-distance badges.

On a finished independent wall, a new or directly edited opening must leave a jamb at each endpoint equal to at least half that wall's real thickness. The same limit applies to placement, drag, rebind and length edits. Existing near-end openings remain visible and are not moved until their geometry is edited.

An opening may bind a contact; doors and gates may also bind a lock. View paints the moving leaf and state. A lock badge is green when locked and red when unlocked. A plan tap never toggles a lock. The opening card provides a labelled lock/unlock control, with confirmation before unlocking.

Openings may slide along joined wall corners. A double click in Plan opens properties. Thick walls keep visible jambs and align the symbol to the correct face.

10. Devices

House Plan reads Home Assistant device, entity and area registries. A device in a bound HA area receives an automatic marker. Service-only records, bridges and other non-spatial records are filtered; a light group may replace its members. Newly discovered devices get a red dot until first opened in Device.

When the Area of a direct HA device or a separately placed entity changes, House Plan moves its automatic marker to the room bound to the new Area. A previous manual drag is layout, not a room override: it is discarded, the ordinary room grid chooses the new position and the red attention dot appears. Selecting a room explicitly in the marker settings overrides HA Area placement. Ambiguous or unbound Areas never make House Plan guess a destination.

Bindings

Binding	Use
HA device	Uses its related entities and resolves a primary function
HA entity	Exact entity binding after enabling “Show entities”
Virtual device	Label/icon/description only, with no live active state

The same binding cannot be used by two markers.

When an exact HA entity belongs to a device, placing that entity gives its channel to the entity marker. The automatic parent marker, if needed, contains only the remaining active, HA-visible and unplaced entities; it disappears when that residual is empty. HA-hidden siblings alone do not keep an automatic parent on the plan. To show both the exact entity and the complete device, place entity:X and device:D explicitly — two explicit markers are treated as an intentional configuration. Deleting an entity marker returns the entity to automatic parent discovery; its binding tombstone does not remove registry data from the live HA device.

After deleting a complete HA device, you can restore only one of its entities: open Devices → Available, enable Show entities, and select that entity. House Plan returns the selected marker with a fresh position while the complete device and its other entities remain deleted. The complete device stays available in Available again if you later decide to restore it explicitly as well.

Device editor

• drag a marker to save its server-side position. One completed drag creates one position-history step; a cancelled, unchanged or failed drag creates none;
• persistent Undo/Redo buttons affect marker positions only. The same session-local history is available through Ctrl/Cmd+Z, Ctrl/Cmd+Shift+Z and Ctrl+Y, keeps up to 50 completed moves, and is not restored after reopening the card;
• click it to edit name, binding, room, tap action and presentation;
• Add opens the new-device dialog directly, without going through the device catalog;
• Devices opens one searchable lifecycle catalog. Its On plan, Available, Hidden and Available again tabs explain where every exact HA binding is and offer the next valid action;
• Discovery filters (#44) live on the Available tab: a switch that groups room lights into one marker (on by default) and the list of excluded integrations with search and a "Restore recommended" reset. Changes show appear/disappear counters before anything is written; Save stores the settings once. Filters only affect automatic candidates — a device you placed explicitly never disappears because of them, and an excluded candidate names its integration in the catalog;
• Add virtual device lives at the top of that catalog. Enable Show entities in Available to place an individual entity;
• Show hidden on plan is a local catalog switch. It reveals user-hidden and HA-disabled records as service ghosts only until you leave the Device editor; it never changes the saved Hidden flag;
• Icon rules edits the first-match regular-expression list.

An automatically discovered marker is already On plan even before it has saved marker settings. The New badge is independent and remains until the marker settings are opened. Find on plan centres and briefly selects the marker without changing config or acknowledging that badge. Hide and Show are reversible; Delete leaves an exact binding tombstone and moves an active HA binding to Available again. A disabled or missing binding keeps its saved category and receives a separate Home Assistant status instead of silently moving to another tab.

The dialog shows binding provenance, exact next tap result, skipped targets and a live presentation preview. A saved missing source is shown as missing rather than silently replaced.

Hidden markers keep configuration and may still contribute to area aggregates. An HA-disabled binding is excluded from rendering, state, actions, light and aggregates until the same ID becomes active again.

11. Tap actions

Gesture	View	Device editor
Short click/tap	Configured action	Open marker settings
Hold 600 ms	House Plan device card	No device control
Right click	Native HA more-info for the primary entity	Browser/editor context

Action	Behaviour	Safety
Device card	House Plan card with entities, model, description, links and files	No state change
HA more-info	Native dialog for the exact primary entity	No state change
Toggle state	Toggles the exact binding, supported device function or configured light-source group	Locks, alarm panels and protective garage/door/gate targets are no-op; confirmation is optional
Run	Runs an automation, script or scene	Explicit target; confirmation is optional
Do nothing	Short click/tap, Enter and Space are ignored	No dialog, command, confirmation, toast or press feedback

When confirmation is enabled for Toggle state, the dialog shows the current state and the exact expected result (On, Off, Open, Closed or Stopped). A group shows the active/total count and lists unavailable targets separately; the result describes only the targets that will receive the command. The text is a snapshot, but Confirm re-resolves the live state and direction. If the target set changed while the dialog was open, House Plan cancels the action and asks you to try again.

A light defaults to Toggle; other devices default to the House Plan card. An unsupported Toggle remains a visible no-op and is never changed into another action behind the user's back. Do nothing is an explicit saved choice, not the default: it keeps the marker's normal appearance, hover, long-press House Plan card and right-click HA more-info while disabling only short activation.

If every explicitly configured controls target is unavailable, missing or disabled in HA, a short tap sends no service call and the standard local House Plan message names the target and explains that no action was performed. A partially available group still operates only its available subset, so it does not show the misleading no-action message.

When a device-bound marker has two or more own light.*/switch.* entities, Entity to toggle appears below Toggle. It selects the exact own channel and updates the target hint before Save. Automatic keeps the previous binding / functional-role rules. A missing saved entity stays configured, shows a warning and temporarily falls back; returning the same entity restores the choice. This setting is independent from Leading light entity. With an explicit external controls group, an explicitly selected own entity joins the group; without a selection existing groups remain external-only.

12. Device visual states

Presentation uses one shared outer shell around three independent layers: stable core, icon or value, and optional activity pulse. Visual priority is alarm → keyboard focus → selected → hover → semantic state → neutral.

State	Meaning	Examples
Red alarm	Critical condition, even with live states disabled	Smoke, gas, CO, leak, tamper/problem/safety, triggered alarm
Yellow	Device is doing its main job	Light/switch/fan on, active climate, vacuum cleaning, known appliance work
Red lock	Lock is unsecured	Unlocked/open lock
Green lock	Lock is secured	Locked lock
Orange	Physically open	Door/window contact, opening valve
Faded	Data unavailable	All relevant entities unknown, unavailable or absent
Neutral	No alarm, work or open condition	Off, closed, idle, standby, docked

For a controller with controls, target work and controller availability are independent. The controlled lights still decide whether the marker is yellow, but only the controller's own active entities decide whether it fades. A live battery, Zigbee LQI or update entity therefore keeps a wireless switch neutral and opaque when all of its lamps are unavailable. If an active physical HA device exposes no entities at all, House Plan also keeps its controller opaque: missing telemetry alone is not evidence that the device is offline, so its controlled target makes it yellow when working and neutral otherwise. If the device does expose own entities but all of them are missing, unknown or unavailable, the controller fades even if a target is on. A virtual controller is always available. This remains true when the same target was separately removed from the plan: the removed marker is not restored, but it cannot make the controller look offline or make its editor preview disagree with the plan.

For a composite appliance with a dedicated Power switch, Power=on alone remains neutral. If Home Assistant also exposes a strict lifecycle entity such as Status/Run state/Job state, active values (start, running, washing, rinse, and similar work states) make the marker yellow; idle, paused and terminal values remove it. Power=off or unavailable still fades the marker even if the lifecycle value is stale. Mode, Program, Stage and remaining time are not treated as independent proof of work, and an ordinary lone relay keeps its existing yellow-on behaviour.

Activity may be a finite three-wave event, persistent presence, a travelling transition, or persistent work. Continuous motion uses a 3.6 s cycle (green presence, amber work, blue neutral transition), a short event lasts 3.3 s, and the two-wave red alarm cycles in 2.4 s. Explicit saved pulse color/size remains authoritative; the package size default is 1.5 diameters. prefers-reduced-motion replaces ordinary motion with a compact colored indicator while the static red alarm remains clear.

The four display choices are icon + state; icon + state + activity; value + state; and always-static icon. A separate value badge can show an entity state, useful attribute, average LQI or linked light state on any side of the marker. For value + state, the Device editor also offers Value source. Keep Automatic (as before) for the legacy choice, or select one of those same readings—for example, cover position—to replace the icon with 42 % rather than Open. A temporarily unavailable saved source stays selected and shows — until it recovers; it is not silently replaced. Changing this source never changes what a click or tap does. Text and adjacent values are sections of the same shell. They shrink to a readable floor and then expand the shell; they are never ellipsized. The complete visible value capsule is one hover and action target: clicking or tapping its value section runs exactly the same configured action and safety checks as the icon core.

Virtual devices use the ordinary neutral/hover background with a dashed outer circle. An HA-less virtual device does not invent unavailable or activity; a linked virtual light may still follow its real controller. Unavailable keeps the ordinary presentation with the standard icon opacity reduction, no visual hover and no motion; its existing click/tap still opens information or settings. Marker LQI uses the same continuous red-to-green scale as before the package update; the room fill gradient and the displayed number are unchanged.

Interactive View/kiosk and Device-editor markers have at least a 44×44 CSS px target. Enter and Space reuse the exact current click and confirmation path; Plan, Background, preview and the read-only static card add no tab stop.

13. Room fills and light

Space fill modes include user colour, temperature comfort range and LQI. Room settings may override the space. Glow is independent from the base fill.

A light source may come from automatic classification, an explicit Always role, or a controlled source group. Walls, partitions and columns occlude Glow; open passages transmit it. When a configured light source disappears or loses its valid binding, its contribution is removed instead of keeping stale light.

Overlapping Glow pools add brightness and colour where browser SVG blending is supported; otherwise House Plan uses a safe normal blend without changing the saved setting.

14. Background editor

The authoritative technical interaction contract is DECOR-EDITOR.md.

While this mode is active, device markers and room labels do not intercept the pointer (#362, #376): drawing works right through them.

The main-toolbar default colour and style for new objects is saved with the plan (#377): it survives a page reload and is shared by everyone who edits this plan.

Tool	Create	Edit
Select	Select an item	Move, scale, rotate; double click properties; Delete/Backspace removes
Backdrop	Available when a plan image exists	Move, corner-scale, rotate; double click numeric size/angle
Line	Drag endpoints	Colour/opacity, physical thickness and solid/dashed style
Rectangle	Drag diagonal; Shift makes a square	Stroke plus independent fill, size and angle
Oval	Drag bounds; Shift makes a circle	Stroke plus independent fill, radii and angle
Text	Click to open dialog	Multiline text, HA tokens, colour, physical size and angle
Furniture	Pick a front-view category, pick a top-view variant, then click	Symbol, smooth size, horizontal/vertical mirror, colour, outline and wall magnet
Image	Upload PNG/JPEG/WebP/SVG or choose a previous upload, then click	Smooth size, horizontal/vertical mirror, opacity, angle and file replacement; no wall magnet
Erase	Click an item	Confirmed deletion, undoable

Creation and ordinary decor transforms snap to the grid plus nearby room/background anchors. Furniture resize is the exception: corners move smoothly and preserve proportion (Shift changes axes independently), while four middle handles change one axis. Crossing the opposite edge mirrors the item. Rotation is smooth and Shift snaps it to 45°; signed size fields and the two mirror checkboxes provide the same result numerically. Furniture is selected within 10 physical centimetres of its drawn strokes, not throughout its empty bounding box. Optimize plans preserves the complete smooth position, size and rotation of furniture and uploaded images; these authored transforms are not grid debt. The plan image is interactive only with Backdrop selected. Undo/Redo shares the 50-command editor history.

The Furniture palette always uses two levels: categories first, then the available plan variants. All categories returns to the first level and disarms the current symbol. Existing placed furniture keeps its saved size and position when the built-in artwork is updated.

The Image palette stores reusable files privately in House Plan. Each saved canonical file is at most 2 MiB; PNG, JPEG, WebP and safe SVG are supported. When a raster source exceeds that limit, the warning dialog offers to upload a reduced copy while keeping the oversized original unavailable. Picking a file arms one placement: the pointer preview shows the result, one click adds it at 100 cm wide (aspect-preserving, height capped at 200 cm), and the tool returns to Select. Images use the same smooth handles, mirroring and Shift-45° rotation as furniture, but never snap to a wall. Their complete rectangle is selectable, including transparent pixels.

Deleting or replacing a placed image leaves the reusable file in the palette. The palette deletes a file only after all placed copies in all spaces are gone. If a file is missing or fails its integrity check, View hides it; Background shows a crossed placeholder that can be selected and repaired with Replace. Exports still keep that image object without embedding the absent file. A later import shows the existing missing-content confirmation and, once confirmed, keeps the same repairable placeholder instead of rejecting the whole plan.

Live text accepts {sensor.entity} and {climate.entity:current_temperature} tokens. Missing, unavailable or complex object values render as —; long values are shortened.

15. Sun background and window rays

These are independent features. Follow the sun changes the background from day through golden hour to night and can fall back to browser time. Window rays require sun.sun, a configured north direction and suitable exterior windows. Weather cloud cover may reduce ray intensity.

For window rays, point the compass N arrow toward the place where true north actually lies on the drawing. The value is the literal clockwise direction from canvas-up to north, not an opposite correction for a rotated plan. If you previously mirrored the compass to compensate for the old ray-direction bug, return it to the real north after updating.

Rays remain visual only: they do not change Home Assistant state. Walls and physical obstacles clip them; changing north or window geometry recalculates the result.

16. Robot vacuums

The dock marker stays at its saved location while a live puck and path follow a supported map source. Calibration maps source coordinates to plan coordinates. Automatic room-name matching is a starting point; manual drag/stretch corrects it. A diagnostic source picker reports missing or incompatible sources instead of silently rebinding.

Multiple maps are represented as distinct sources/calibrations. A vacuum is shown only in the space whose saved mapping currently matches the active map; the dock remains in its configured space. Deleting a vacuum marker erases its server-side trail immediately; adding the marker again starts the trail from scratch. See VACUUM.md for the source dialect and calibration contract.

17. Kiosk

Set kiosk: true on a card in a Panel view. Editors and the ordinary header are removed. Pinch/drag navigate, double-tap resets, and a 1:1 horizontal swipe changes space. Holding empty space for three seconds opens per-display icon and text sizing. cycle enables automatic space changes; interaction pauses it for 60 seconds.

18. Static space card

custom:houseplan-space-card renders one configured space without live states, hover, drag, more-info or actions. A footer button opens the full plan. Use it for compact dashboard navigation, not for home control.

The compact card keeps radial light pools and wall shadows off by default, so existing dashboards retain the cheapest render path. Set light_pools: true to show the full plan's Glow: the same source colour, brightness and radius, additive overlap, passages and shadows from walls, partitions and columns. This is independent from live_states; disabling ordinary live marker dressing does not disable light transport. The option is intentionally heavier than the default because every visible source needs clipped floor visibility geometry.

type: custom:houseplan-space-card
space: ground
fit: house
light_pools: true

fit controls only this compact card's frame:

• content (default) keeps the existing frame around all visible content and its 5% breathing room;
• house removes that intentional padding and fits every room, every visible opening symbol, and — when show_borders keeps them visible — every wall, partition and column (#384: hidden architecture does not widen the frame). A detached but valid wing stays in the frame. Backdrop, decor, room labels and device markers do not widen it.

Choose house when the building should occupy as much of the card as possible. Auxiliary objects remain rendered, but an object outside the structural bounds may be clipped. An image-only or empty space safely falls back to content.

By default the card uses the configured space name as its header. A non-empty title replaces that text. Set title: "" explicitly when the surrounding dashboard already provides the name: the header is omitted and the plan meets the top of the stage, while the normal left, right and bottom breathing room is kept. Omitting title is not the same as setting it to an empty string. With fit: house all four intentional paddings are already zero, so title: "" removes only the header and leaves the same structural frame.

19. Plan maintenance

Current plans give every stored wall segment a stable internal identity. This keeps the wall's thickness and its door, window, gate or passage attached while Resize, Split, Merge and other structural tools change surrounding geometry. There is no new control and the plan is not rewritten merely by opening it.

An older plan is upgraded atomically on its first structural edit or when you run Optimize plans. Names, colours and other presentation settings do not trigger the upgrade. If old geometry is ambiguous, House Plan cancels the edit without partially saving it and asks you to run Optimize plans. If the same message remains, fix the reported conflicting wall geometry or attach that space's export to a bug report.

Optimization compacts old off-grid geometry and repairs the plan's reference graph while preserving rooms, bindings and supported settings. An exact independent-import signature restores the copied space, room and positions. If there is no exact copy, an active real device follows its unambiguous HA Area; otherwise only its missing placement is detached, so the marker becomes available on a valid plan without losing its settings.

Old plans can also contain invisible floating-point tails around ordinary grid nodes. Optimize reports how many coordinate values it will canonicalize, the maximum physical movement and only the affected spaces. This cleanup does not pull intentional off-grid or diagonal geometry to a node. Current ordinary edits apply the same invisible boundary automatically, so the noise cannot return after a later room, opening, decor or marker-position save.

Equal neighbouring wall-thickness fragments are compacted only while they have the same physical role: one outer room or the same pair of shared rooms. A shared-to-outer transition or a change of shared-room pair stays as an exact breakpoint even when the thickness is equal. Optimize may also remove a different-thickness fragment shorter than half a grid step when equal pieces of the same straight wall prove the replacement. This includes a fragment touching exactly one room T-junction: the junction and perpendicular wall do not move. A fragment between two room vertices or touching an opening boundary is preserved. Ordinary opening, rendering, Save and editing never perform this cleanup without explicit Optimize confirmation.

Before an editor stores a change to rooms, walls, boundaries, openings, partitions or columns, House Plan builds the exact candidate with the same physical-geometry engine used for display. If the result is unsafe, the change is canceled before Undo history or server storage is touched and the card reports that the wall geometry could not be built safely. Titles, colours, markers and other non-geometry settings remain editable.

When an old plan contains an independent wall exactly on top of solid room masonry, Optimize can absorb each proven covered section even when consecutive room-wall intervals form the cover. Free or ambiguous residual sections remain independent walls with stable identities. Doors, windows and gates stay in place: each is reattached to the room wall or to the retained residual that still hosts it. The resulting thickness is the wider original thickness, so visible masonry does not shrink. Each independently stored section is absorbed only when it is fully redundant; a free, partly covered or thicker partition remains unchanged. The report counts absorbed independent-wall sections.

Every Plan editor tool draws room and independent-wall centre axes and endpoint nodes through the same layer above wall bodies. An independent wall hidden under other masonry additionally retains its source diagnostic axis and nodes. These pointer-transparent layers do not change snapping or selection and are absent outside the Plan editor. The diagnostic disappears after Apply only when the corresponding independent geometry was safely absorbed or removed.

Old positions are classified before Apply. A position whose room label, device or light-group owner is proven absent is removed automatically and counted by a plain-language category. A live owner in a deleted space is named and preserved by default; Remove old positions explicitly adds only those entries to the same Apply candidate. An owner that cannot be checked against a complete HA registry is preserved without a destructive action. Raw IDs appear only inside collapsed Details, and vacuum room mappings remain a separate warning for manual review. Preview, the secondary option and Cancel do not write anything. Plan images and attachments are never deleted merely because nothing currently references them.

Optimization creates one server-side undo point which restores automatically and explicitly removed positions with the rest of the previous layout. Any later edit makes that undo stale, so create a Home Assistant backup before a large maintenance operation.

20. Storage, multiple cards and backups

Portable JSON backup

Global settings → Backup and transfer exports either the complete House Plan model or the current space. Import first shows a server-side preview with type, versions, object counts, source and content-link state; nothing is written until confirmation.

A full import replaces the model and creates one undo point. A space import assigns new internal IDs and adds the copy without replacing global settings. When that exact import map matches orphan references already present in the target, the preview reports them and Apply restores them together with the space. Re-importing a copy still creates an independent space, but no longer grows nested service prefixes in internal IDs. Preview and Add space use the same prepared candidate. Import reference details reports links updated inside the copy and in the existing plan. If more than one target is possible, House Plan preserves the reference instead of guessing and recommends running Optimize plans after the import. Internal uploaded files are not embedded in JSON; an import to another HA instance must explicitly detach those links.

For Current space, enable Plan only to transfer the architectural template without devices or Home Assistant bindings. It keeps rooms, walls, openings, decor, backdrop transforms and manually positioned room labels at their chosen scale, but removes real and virtual markers, device positions, Area assignments, temperature/humidity sources and opening contacts/locks. Live values in text labels become —; surrounding static text stays intact. The import preview marks this file as plan-only and adds it through the normal space-import flow.

Plan-only is not full anonymisation: space and room names, static text, file names, exact coordinates and external URLs remain in the JSON. Internal plan files are still referenced rather than embedded and may need to be detached on another Home Assistant instance.

Importing a plan from Sweet Home 3D

If the home is already drawn in Sweet Home 3D, there is no need to draw it again: the converter at houseplan.tech/convert turns a .sh3d file into import documents — one per level. From there it is the ordinary space import under Global settings → Backup and transfer.

This is an optional shortcut, not a setup step: the normal paths — a background image or drawing from scratch — stay unchanged. The conversion runs in your browser; the file is never uploaded.

Carried over: levels, rooms with their names, walls with thickness, doors and windows. Not carried over: furniture, materials, textures, lights, cameras — and the binding of rooms to Home Assistant areas together with device placement, because the file has neither; both are done in the editor. Curved walls are straightened, walls thicker than 100 cm are clamped to the limit, and a level with no drawn rooms cannot be converted at all — House Plan builds geometry from rooms. The page lists every such case before you download anything.

Several cards and clients

Use floor when separate card instances must stay on separate spaces. A stable space ID is recommended:

type: custom:houseplan-card
floor: ground
kiosk: true
cycle: 0

YAML also accepts an unquoted zero-based numeric index such as floor: 1. Indexes follow the current server space order, so reordering spaces may change which one is shown. A quoted value such as floor: "1" is a literal space ID.

A pinned card shows only its assigned space. It ignores the browser's shared last-space record, #space= links, other floor tabs, swipe and kiosk cycling, and it does not overwrite the shared last-space record. If the configured ID or index is invalid, the card shows a configuration error instead of choosing another space. Remove floor to restore normal navigation.

Unpinned custom:houseplan-card instances may still use different default_floor values. That option is only the initial/fallback choice; the last selected space, a valid #space= link or normal navigation may replace it. If the saved id no longer exists, runtime still opens the first valid space and the visual card editor shows the raw missing id with an inline warning until a valid choice is made.

• configuration, rooms, Background and device layout are shared server data;
• floor is a permanent per-card navigation authority, while default_floor is only an initial/fallback choice for an unpinned card;
• current mode, selected space, zoom/pan and kiosk sizing are local;
• WebSocket broadcasts saved changes and revision checks reject a stale write;
• avoid editing the same object in two browsers: the second save may need a refresh and manual reapplication.

Every client that saves the shared configuration must return the revision from houseplan/config/get. Omitting it is allowed only while the configuration store is still empty; afterwards House Plan rejects the save as a conflict instead of risking another client's work. If an old cached card repeatedly reports conflicts, update House Plan and refresh the dashboard.

Files and quotas

Plan files accept SVG/PNG/JPG/WebP up to 8 MB, with a 200-file/256-MB total. Marker attachments accept PDF/PNG/JPG/WebP/TXT up to 50 MB, with a 1000-file/1-GB total and 50 links per marker. Writes are also refused below 512 MB free disk space. Detached files remain until explicitly deleted.

21. Current limitations

Limitation	Practical effect
Rooms must be closed	An open path is walls, not a room with area
One HA area per room	To split one HA area visually, assign devices manually
Zero-thickness walls cannot host openings	Give the target wall a positive thickness before adding a door, window, gate or passage
Editors are desktop-first	Touch editing may be awkward, limited or absent
Room details use hover in View	A touch-only user may need an editor or another visible metric
Sun has no exterior 3D model	It cannot know shadows from trees, awnings or neighbouring structures
Icon rules use regular expressions	First matching rule wins and invalid expressions are rejected

Storage guards allow up to 50 spaces, 400 rooms per space, 2,000 markers, 500 openings, 1,000 Background items and bounded wall/physical-object catalogues per space. The configuration package is limited to 2 MB.

22. Troubleshooting

Card does not load

Symptom	Check
Custom element doesn't exist: houseplan-card	Integration loaded; resource is /houseplan_files/houseplan-card.js with type module; restart HA, then hard-refresh with Ctrl+F5 (Windows/Linux) or Cmd+Shift+R (macOS)
MIME text/plain	Replace /custom_components/... with /houseplan_files/...
Integration missing	Folder is exactly custom_components/houseplan; restart HA; inspect import errors

Devices or values are missing

• confirm the room's HA-area binding and the device/entity registry area;
• open Device → Devices and inspect Hidden / Available again;
• verify the selected source still exists and is available;
• remember that a virtual marker has no active state;
• inspect the dialog's exact target and skipped-target explanation.

Geometry looks wrong

• confirm grid cell size before judging physical dimensions;
• use Fit all to include distant objects;
• check wall thickness and the space's zero-thickness wall style;
• use desktop for precise nodes, Split and Resize.
• if some masonry remains visible but Optimize or an edit reports unsafe wall geometry, export the affected space and attach it to a bug report. House Plan preserves known-valid wall components for inspection and does not repair or delete the ambiguous object during rendering.

Vacuum does not move

• confirm the active map source and map identity;
• check calibration anchors and current source availability;
• verify that the active map is assigned to this space;
• open source diagnostics instead of deleting/recreating the marker.

When reporting a problem, include House Plan version, HA version, browser, console/server errors and reproducible steps. Replace private entity IDs and plans with synthetic equivalents.

23. Help and private feedback

The Help & feedback button follows General settings in the card header. It is available to users allowed to edit House Plan in View and all editors, but is hidden in kiosk. The dialog contains the current card version, the GitHub and Telegram links, and this guide. Russian UI opens the Russian guide; all other languages open this English guide.

Enter a required message and, optionally, a contact such as an email, Telegram username or WhatsApp number. The form is kept only in the open card instance: it is not written to House Plan settings, local storage or Home Assistant.

The diagnostic attachment is off by default. When enabled, House Plan builds an allowlisted package in the integration and shows its exact size, SHA-256 and JSON before sending. The package excludes names, Home Assistant entity/device/area IDs, live states, URLs, paths, files, message and contact. It does include exact room/wall/opening geometry and home dimensions. Use Show data to inspect the exact bytes and Download JSON to keep them. The preview expires after ten minutes; refresh it before sending if required.

On success, keep the report ID shown by the dialog. A network or relay failure does not close or clear the draft and never claims delivery: retry with the same preview, or copy the message/download the JSON and continue through the provided Telegram or GitHub links. The form is available when the card and integration support the same feedback API; their release numbers may temporarily differ during a normal HACS update. Update an old or incompatible side. Retention and deletion details are in SUPPORT-PRIVACY.md.
