`.room { transition: 0.12s }` interpolates a room's colour and its
fill-opacity / stroke-opacity independently, and the visible opacity is their
product. The states without a fill kept their alpha in the colour with the
default opacity 1 (.overlay transparent, .yard rgba 0.14, .outlined rgba
0.06 / 0.55, .picked rgba 0.25), while .styled writes an opaque colour plus
fill-opacity: var(--room-fill-op). On a change between the two on the same
node one half rose while the other fell, and mid-way the room was darker than
at either end. Opening the space settings on a floor with no fill (the dialog
shows "no fill" as its own colour at alpha 0) flashed every room grey for
~0.1 s, 0 -> 0.241 -> 0; cancelling the dialog after a preview, entering and
leaving the plan editor briefly darkened the fill (0.18 -> 0.317 -> 0.06).
Every .room state now writes an opaque colour plus *-opacity, and
transparent only together with a zero opacity. The transition itself,
.styled and the --room-* variables are unchanged; the space card takes the
same styles. The resting paint is the same: the witness records each state's
colour and visible opacity as dev drew them, and screenshots of seven resting
states (View without fill, with fill and borders, plan editor, room picked for
a merge, yard with and without borders, yard in the plan editor) are
pixel-identical to dev outside the plan editor's tool hint, whose text shifts
by a sub-pixel between runs on dev too.
Witness: new demo/smoke_room_fill_transitions.mjs, deterministic. A
MutationObserver pauses the room's transitions at their first frame right
after Lit commits, and the smoke seeks them through 0..120 ms in 15 ms steps.
Red on dev: fill overshoot 0.241 / 0.125 / 0.137 / 0.134 on the four paths,
stroke 0.241 / 0.242 on the first two. A real colour change of the same room
still runs a fill transition (catches `transition: none`).
A card-mod rule that sets only `fill` on an unfilled room now meets
fill-opacity 0; CHANGELOG and STYLING-HOOKS say to set the opacity with the
colour (the values are generated, STYLING-HOOKS §3.3).

🏠 House Plan — a live home map for Home Assistant
📘 Full user guide · 🇷🇺 Русский · 🗂 Project issues
Your whole home at a glance
House Plan turns Home Assistant into a live map of your home. Open the dedicated House Plan item in the Home Assistant sidebar, upload a plan or draw rooms, bind them to Home Assistant areas, and the area's devices appear automatically. You can immediately see where a light is on, a door is open, a room is too cold, Zigbee signal is weak, or a leak sensor has fired.
Setup is entirely graphical: no floor-plan YAML, Inkscape, or external editor. Plan data and device positions live on the Home Assistant server and stay in sync across screens.
Edit on a desktop computer. View and kiosk are fully supported on phones and tablets. The editors are designed primarily for a mouse and keyboard; individual touch editing operations may be awkward or unavailable. See the exact touch support contract.
What House Plan provides
- Live state and safe actions. Lights and other safe devices can toggle from the plan; a lock cannot be opened by an accidental plan tap.
- Three built-in editors. Plan creates rooms, walls and openings; Device places and configures markers; Background adds lines, labels and furniture.
- Area-aware rooms. New devices appear automatically, while room cards can show temperature, humidity, light state and average LQI.
- Light and environment. Room fills, lamp Glow, wall shadows, a day-cycle backdrop and sunlight through windows.
- Flat or 2.5D. One switch in General settings › Display shows the plan with depth everywhere: raised device tiles with soft floor shadows and a soft wash of sunlight; decor and wall colours stay as you set them.
- Doors, windows, gates and vacuums. Openings follow real contacts and locks; a robot can show its position, dock and travelled path.
- Several floors and screens. Space tabs, swipe navigation, local viewport, and a separate initial floor for each card.
- Wall-display kiosk. A plan-only view with fullscreen navigation and icon sizes saved for that display.
Your first working room
- Install the integration and open House Plan in the Home Assistant sidebar.
- Create the first space: upload SVG/PNG/JPG/WebP, reuse an uploaded image, or choose no image and draw the plan by hand.
- In Plan, select Walls and draw one continuous chain around the room: when it closes an area, the room dialog opens.
- Name the room and bind it to a Home Assistant area. Use “No area” for a room that has no devices.
- Open Device: devices from the bound area are already placed; drag their markers to the correct positions.
- Optionally use Background for lines, text and furniture.
- Return to View. The plan now displays live state and accepts safe actions.
Every workflow and edge case is in the full user guide. The Background editor contract and vacuum guide are the authorities for those subsystems.
Installation
HACS
House Plan is in the HACS default catalog — no custom repository needed.
- In HACS search for House Plan and install it.
- Restart Home Assistant.
- Open Settings → Devices & services → Add integration → House Plan.
The sidebar page and optional dashboard cards are registered 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 the on-disk path inside custom_components; Home
Assistant does not serve that path as a JavaScript module.
Manual installation
Copy the complete custom_components/houseplan release folder to
config/custom_components, restart Home Assistant, and add the House Plan
integration. Do not copy only houseplan-card.js: the card also uses an
internal manifest and content-hashed modules from the same release.
Open House Plan
After the integration is added, open House Plan in the Home Assistant sidebar. This full-page view is the primary entry point and needs no dashboard or YAML setup. It remembers the last space but always returns from another HA page in View rather than reopening an editor. Users without editing permission see the same live plan without editor controls.
If the sidebar entry cannot be registered, the integration and existing dashboard cards continue to work; check Settings → System → Repairs → System information → House Plan after restarting and hard-refreshing HA.
Optional dashboard card
Add the card only when House Plan must be embedded in a dashboard. In a Sections view it requests full width by default, while a manual size chosen in HA remains authoritative. Add it in the UI or as:
type: custom:houseplan-card
title: House plan
Different screens may start on different spaces:
type: custom:houseplan-card
default_floor: ground
All cards share server-side rooms and coordinates. Current mode, viewport and selected space remain local to the screen. Revision checks and live sync cover concurrent clients, but avoid editing the same object in two browsers at once.
