# NeonPlan 3D
**by Mastershort** – draw your home right inside Home Assistant and live in it as a neon 3D house: lights glow in their colours, blinds and curtains move, doors and windows open, cameras watch, the TV shows what is playing, energy flows through the walls – and you can simply **talk to it**. No external tools, no cloud, made for wall tablets – old Fire tablets included.
▶️ **Try the online demo** – in your browser, with invented demo data: turn the house, switch lights, open the editor. Nothing to install.
📖 **Manual:** English · Deutsch (also here: manual.md, anleitung.md)
💬 **Community:** Discord – show your 3D home, ask, share ideas

## Your house in three steps – no CAD, no Blender
Everything happens in the editor inside Home Assistant, with the 3D house growing next to the plan while you draw.
| 1. Draw | 2. Furnish | 3. Link |
|---|---|---|
| | | |
| Rooms as rectangles or free shapes – walls, corners and measures follow by themselves. Doors, windows, stairs, roofs and the garden come from the same toolbar. | Pick furniture by room and kind, each with a picture and its size; one card per item with its sizes, left and right versions. Resize freely – legs and arms stay as they are. | Each room takes its Home Assistant area: lights, blinds, sensors and media are found and placed with one tap. From then on the house is live. |
Not drawing at all? The import page turns Sweet Home 3D, iPhone LiDAR scans and more into a plan (see below).
## Highlights
- ✏️ **Drawn in minutes, right in Home Assistant** – the plan editor with the 3D view beside it, a furniture library with pictures, free sizes, a wall view for exact placing. No external tool.
- 🎙️ **Talk to your house** – tap the microphone or ask Assist: "Show the living room", "What's open?", "Good night". Assist satellites and automations ask the house too (service `neonplan3d.ask`); the answer module "Das Haus antwortet" is in beta for supporters.
- 🎬 **Live director** – the wall tablet shows by itself what happens: the doorbell rings and the view flies to the front door and looks through its camera; someone at a camera, the washer done, a warning. Every event is opt-in.
- ⏪ **Time travel** – replay the last day or week in the house: lights, doors, motion, the robot's run.
- 🚶 **Walk through the house** at eye level, with keys or a touch stick.
- 🔋 **Energy in the walls** – solar, battery, grid and wallbox as glowing cables, holograms with day curves.
- 📱 **Runs on old wall tablets** – a *Tablet* quality level, nothing is drawn while nothing changes, and the build refuses browser features old Fire WebViews lack.

Three looks, an accent colour of your choice, and **Auto** – day while the sun is up, neon after sunset.
