Rotate a model of the room, tap a lamp and watch the real light change. Joris / u/JorisDBie built this Home Assistant dashboard with Claude Code, using a floor plan and photos of his rooms.

Image-generation attempts kept changing the layout. He switched to a model built in code, then corrected furniture and light positions through repeated prompts.

It is a personal project and a fun way to explore a smart home; the creator still relies on motion sensors for everyday automation.
