I have a weirder utility for it: occupancy sensing in rooms.
If it can detect breathing of humans reliably, then it solves a huge problem in having home automation with automatic lighting - particularly in bathrooms. I've never had a decent bathroom occupancy sensor (they all end up wanting to detect fairly large motions) - the obvious solution is AI with a camera but for obvious reasons no, but if a couple of base stations can localize person positions to rooms in the house (and provide other services) then that kind of solves the whole issue!

- XorNot 4y agoI grew up with a father who was obsessed with the idea that we were wasting electricity by accidentally leaving the lights on sometimes. As a result he's spent probably thousands in attempted energy saving devices which have all not worked and definitely would never save enough compared to the cost of them. Which is why I think about these things despite this seemingly obvious solution. And the fact that the guest bathroom when I visit his house still has no light switch but does have a cheap motion sensor which is annoying as hell.
- eightysixfour 4y agoThere are a number of mmWave occupancy sensors that are more than capable of this. The biggest issue is the delay introduced in most smart home contexts by Zigbee and the hubs. Matter/Thread should help here. Existing options: https://smarthomescene.com/reviews/best-mmwave-human-presence-sensor-comparison/ https://smarthomescene.com/reviews/best-mmwave-human-presenc... The Aqara FP2 should be out in Q2 with Matter support and be a nice upgrade. It can segment a room into multiple spaces and detect 5 people.
