@tufo oh, to add to this, since it isn't in that post: I can't confirm it, but I do have the feeling that it works worse during winter, out of me wearing thicker pyjamas and covering with thicker blankets interfering with the sleep detection heuristics in some way.
@tufo yeah, same... specially since it'd enable porting that to other (maybe custom) devices, right now I haven't seen anything for it out of proprietary solutions
I do have the feeling that being still for a period of time is one of the things evaluated, and I suspect that the sound of one's respiration too. I wonder if the heart rate influences it as well.
it does happen to me often, in slow mornings where I might not get up right away, that me just laying down, closing my eyes, and being very calm, even if still conscious, does trigger a sleep event, so... I wonder how does it do it
@kitten have a garmin watch now, so I'll need to figure out how to get data from that still, but on my old Samsung watch I used home assistant to ingest the data from my phone
