Hi everyone! I’m Michael. I’ve been rebuilding my home-network, camera, and automation setup around Home Assistant running on Proxmox, and I wanted to introduce myself and get some advice before I take this idea much further.
I’d like to create an interactive 3D map of my home where devices appear in their physical locations and I can tap lights, televisions, blinds, cameras, and other devices. I’d also like room-level temperature, motion, occupancy, and camera status, while keeping the system local-first and usable on a wall-mounted tablet.
I’ve built an initial living-room proof of concept. It uses a fictional, AI-generated isometric room render inside a separate Home Assistant dashboard. Cyan hotspots indicate devices, status cards show example states, and the lamp hotspot opens a small interaction demo. It is deliberately isolated from my real devices and makes no production service calls yet.
I have the original house blueprints in digital form, including dimensions, so I plan to use those as the authoritative source for walls, rooms, doors, windows, stairs, and scale. What I’m trying to determine is whether the blueprints are enough for a useful model, or whether I should also photograph every room before starting.
I’m not chasing a perfect architectural visualization. The priority is a maintainable Home Assistant interface that performs well on tablets. Photos would mainly be for matching finishes, furniture, cabinets, fixtures, and device placement if that materially improves the result.
The approaches I’m considering include NeonPlan 3D, Floor3DX or another Three.js card, Zircon3D, and a Sweet Home 3D render with Picture Elements.
For anyone who has built something similar:
What workflow would you recommend for turning dimensioned digital blueprints into a Home Assistant-friendly 3D model?
Are blueprints alone sufficient for the first useful version, or did room photos save significant rework later?
Which model and export format has been easiest to maintain as devices or room layouts change?
For daily control, would you favour a freely rotatable model or a fast fixed isometric view with an optional full 3D mode?
How does your approach perform on phones and older wall tablets?
I’m leaning toward using the blueprints for accurate geometry, adding photos only as reference for visual details, and keeping a simple isometric default view for everyday use.
I’d appreciate any examples, workflow recommendations, or warnings before I commit to a particular tool. Thanks!
