mmwave sensor, humidity sensor, and/or monitoring your water heater power usage. any of those 2 should work.

I am actively working on a bunch of ML algorithms for home assistant for exactly this type of thing, detecting ‘activity’ per room.

hmm, I think it should still work through glass, it works through drywall.

if/when you can afford it, mmwave precense sensors are way better, mine can see me through the shower curtain standing still

if it keeps on happening, test your ram. any weird computer/hardware issues I’ve ever had (and I’ve done a lot of wild stuff for work), is either memory failure or a grounding problem (so maybe your power supply)
