✨ What it does


✏️ Plan editor	Floors, rooms, curved walls, doors, windows, shaped stairs, outdoor areas and roofs, drawn in Home Assistant with the 3D view beside the plan. Areas within a room, layers, inside sizes, wall thickness per part, rooms open to the floor above, turned roof sections, DXF import.
✓ Plan check	One list of what is missing or off – rooms without an area, devices not placed, overlapping rooms, doors off their wall, links to entities that are gone – standby eaters with their yearly cost – each with a fix in one tap. A short tour for a new plan and the sheet of keys (press `?`).
📐 Areas & paper	Living area per room, floor and house, counted like the German Wohnflächenverordnung; the plan on paper at 1:100 with measurements and a table of areas, to print or save as PDF.
🕘 Versions & notes	Named states of the plan ("before the renovation") that stay, compared with the plan now; notes pinned to a spot, with a due day, as pins in 3D and found by the search.
💡 Live 3D	Tap to switch, swipe to dim, long press for colours. Lamps with several bulbs, blinds (roller, venetian slats, inside blinds, Somfy My), windows and doors follow their entities; a room panel lists everything in the room, scenes first.
✨ Light designer	Save a room's lights as a mood, set it again with one tap, carry it over to another room.
🌡️ Room climate	Heat maps for temperature (summer and winter scale), humidity, CO₂, mould risk and a comfort score, airing hints, low batteries, lights left on in empty rooms, each room's 24-hour temperature curve, underfloor heating that glows.
☀️ Sun & power per room	Heat maps for the hours of sun each room gets today through its windows (from the plan, its compass and the sun's path) and for what each room draws now; in the room panel also today's and this month's kWh and cost, the sun over the year, a shade hint when the sun heats a room and a hint when a window stands open while the heating runs.
⚡ Energy	Solar fields (also east-west racks), power flow along real cable routes, battery charge on the unit, gas and water meters, a meter per floor, the last 24 hours and seven days on the house card.
🤖 Sensors for automations	Open windows and doors and Lights on as Home Assistant sensors, for the house and every floor, with the entities in their attributes. Everything off per room or floor, with undo.
🔥 Heat pump & 🖨️ 3D printer	Live cards: flow and return, heat and COP; print progress, time left, layer, temperatures and filaments – the print grows on the bed.
🚗 Car	Charge, range, charging along its cable from the wallbox, departure time, distance away, open doors and hatches, lock and climate buttons.
📶 Wi-Fi map	Every access point's reach on the floor, its devices, and which network devices are offline.
📅 Today	The day's appointments and the bins due, on a card for the wall tablet.
⚠️ Warnings	Smoke, gas, water, the alarm with the sensor that set it off, windows open in the rain, contacts that stop answering – and your own warnings for any entity.
📢 Announcements	"Dinner is ready!" in the room that should hear it, through its speaker and on every open NextFloor screen.
🏡 Household & garden	Waste bins, mailbox, thirsty plants, pets that roam the room they really are in, robot vacuums and robot mowers on their lanes, sprinklers, pools with temperature and pump, gardens linked to their Home Assistant area, 🧹 Clean per room, the fuse box's circuits per room.
📺 Media	TV screens with cover and ambilight; a quick menu for every speaker and TV with sources, volume and presets per speaker.
🛋️ Furniture	40 basic models and 41 packs with almost 800 more – season and decoration, wellness, music, loft, Japandi, workshop, vehicles, picture frames with your own photos – L- and U-sofas, IKEA sizes, Tesla models in their paint. Any piece can show only while a helper is on.
🚶 Walk and time travel	Walk through the house at eye level; replay the last hours or days.
🖥️ Wall tablet ready	Kiosk mode with night dimming, the star menu open and large, zoom and a kept camera for small screens, quality that steps down by itself on slow tablets, an easy-to-read mode with stronger contrast and larger text.
🎨 Fits your theme	Colours, font and corner radius from Home Assistant; looks Neon, Blueprint, Day, solid painted walls.
🧩 Card, plugins, languages	`custom:nextfloor-card` with a visual editor, a plugin system with its own store, and ten languages (now with Simplified Chinese).
🪑 Build your own	The 🛠️ furniture studio right in the editor (cabinets with doors and drawers, shelves, lamps, devices with a display), the furniture builder and a community store, own `.glb` models, Sweet Home 3D and DXF import, a plan format an AI can write – and share a view of your house as a file that opens in any browser.

New in 0.22: the furniture studio in the editor, the heat map by hours of sun with the room panel, the plan check, and the plan on paper with living areas

A picture frame with an own photo, an L- and a U-shaped sofa, a 3D printer printing with its live card, and a home battery showing its charge

💚 Free forever – a promise

NextFloor is free, and it stays free. Not "free to try", not "free with a paid Pro", not "free until the next version": free, for everyone, forever. Every feature, every furniture pack and every update belongs to everyone the day it comes out.

Nothing to buy, ever. No Pro version, no paid modules, no packs sold one by one, no supporter pass that gets features first, no licence key, no shop. Everything – the weather outside, the energy flow, TV screens and speakers, the car, announcements, household and garden, the heat pump and the 3D printer – is simply part of NextFloor.
New furniture all the time, for free. 41 packs with almost 800 models come with it, and new packs keep coming with the updates.
Build your own furniture. The furniture builder runs in your browser: build it, see it exactly as NextFloor draws it, and share it in the community store, where everyone installs it with one tap.
Extend it yourself. A plugin system with a reviewed plugin store: new device kinds, light animations, room cards – from anyone.
Your data stays home. No account, no cloud, no usage data sent anywhere.
The promise is in the licence. NextFloor is MIT licensed: anyone may read, change and share it. Nobody can ever take it away from you – not even me.

I believe in open source: software that anyone may read, change and share, and that every home can use without paying a cent. That conviction is the reason NextFloor exists. It began as a fork of NeonPlan 3D and went its own way, carried by this one promise and shaped together by the people who use it.

🚀 Installation

HACS (recommended)

NextFloor is in the official HACS store: open HACS, search for NextFloor and download it (or click the HACS button above).
Restart Home Assistant.
Add the integration: or Settings → Devices & services → Add integration → NextFloor.
Open NextFloor in the sidebar, switch to Editor and draw your first floor.

Already installed as a custom repository? Nothing to change. NextFloor is now part of the official HACS store, your installation, plan and settings stay as they are and updates keep coming through HACS. HACS lists it as a regular repository by itself once it has refreshed its list.

Manual: copy custom_components/nextfloor into config/custom_components/ and restart. Requires Home Assistant 2025.1 or newer.

📦 Your own 3D models

Own a model of a vehicle (.glb)? Open Extensions in the NextFloor panel, choose the file, turn the front towards you, pick the level of detail and store it on your Home Assistant. NextFloor does the preparation in the browser and ships no models. See docs/models.md.

🔒 Privacy

The plan, its pictures and the packs live in Home Assistant's .storage. NextFloor does not talk to the internet on its own; only if you switch on the optional real map, your browser loads map tiles from the tile server (OpenStreetMap by default). Pictures and history come from your own Home Assistant.

🤖 Made with AI

NextFloor was built entirely with AI assistance. The idea, the decisions and the testing in a real house come from a person; the design, the code, the tests and the documentation were written together with Claude (Anthropic) in Claude Code. I would rather say so openly than let you guess.

What that means for you:

It is tested, but young. There are automated tests (frontend logic, the furniture packs, the Home Assistant side) and releases are looked at in a real browser and installed on a real Home Assistant, but it has far fewer users than most integrations. Expect rough edges and report them.
Back up before you trust it. The plan lives in Home Assistant's .storage; the editor has a backup and restore of the whole plan.
Read the code if it matters to you. It is MIT licensed and small enough to read. Pull requests are welcome, also ones written with AI, as long as you say so and have run the checks (see CONTRIBUTING.md).

🛠️ Development

Build, test, preview

cd frontend
npm install
npm test            # pure logic
npm run typecheck
npm run build       # writes the bundles to custom_components/nextfloor/frontend (committed)
npm run screenshot  # renders preview/index.html (invented demo data) with a local Chrome or Chromium

Preview without Home Assistant: open preview/index.html through any local web server.
Deploy to a test instance: create deploy.local.json with {"target": "<config>/custom_components/nextfloor"} and run npm run deploy in frontend/.
Python tests run in CI with pytest-homeassistant-custom-component.
Furniture packs: the built-in packs are generated by tools/build_packs.py. The format of your own packs is described in docs/packs.md (German).

🙏 Credits

NextFloor started as a fork of NeonPlan 3D by Mastershort (Torsten). The idea of a live 3D home right inside Home Assistant, and the groundwork NextFloor grew from, are his. NextFloor carries that idea on in its own direction: entirely free and open source, for everyone. Thank you, Torsten!
