I used AI to get it draw it. What worked is giving floor plan I already had and putting some labels on it - brown dining table here, fridge here, etc.
What didn't work was giving it bunch of photos and asking it to just figure it out. For things it did figure out - it was nice, but it made way too make mistakes.
The entire point of it was to put light switches and heaters on the map so I don't have to fiddle with a number of toggles in a table/list.
p.s. I wish I had huge eink display for home assistant dashboards. Some concepts I made and seen online are glorious.
