I'm so excited to play with this. I just ordered one. I've gone through two Oura rings (I do not reccomend). I'm not sure this will be reliable but it cost me $14.00 not $300 and doesn't charge me monthly to access a mediocre api.

Oura rings do seem to have accurate tracking (unlike most smart watches). The data it collects and the subscription model look awful though.

Im eagerly awaiting a ring sleep tracker like it which can be used offline with gadgetbridge or something.

Support for this ring (Colmi R02) was added to Gadgetbridge, so I suppose your wait is over: https://codeberg.org/Freeyourgadget/Gadgetbridge/pulls/3896

The sleep tracker seems to be quite poor - e.g. misrecognizing time spent in bed as time asleep. This was the same problem I had before with a xiaomi. It was so inaccurate on all fronts I just ditched the thing.

I wasnt expecting the colmi to be accurate for this low price, but still.

For gadgetbridge I dont think there are any good sleep trackers and the only two I know of that are genuinely accurate are the apple watch and oura (theres a guy who tests them all on youtube - this is what he found).

Id happily pay extra for a decent non-apple local storage only fitness tracker which integrates with OSS and doesnt upload every heartbeat to the cloud but it does not seem to exist.

Nice, I hadn't seen the gadgetbridge support PR before, will be good for a lot of people I think
