Python client for the $20 Colmi R02 smart ring

Cool. Just ordered one (from Temu, $18) even though I already wear an Apple Watch. Love the idea of having something I can interface with directly and pull realtime data from without having to install some middleman phone app.

I just did the same. I'd love to try augmenting the sleep tracking data from my Apple Watch with the sleep tracking data from this ring. A couple of months ago, I learnt from this YT video[1] that sleep tracking gadgets are all quite inaccurate compared to a proper polysomnography study. But they're all inaccurate in different ways.

Right but if it’s the same sensor you are wearing each night you can still learn something from the trends instead of relying on the raw numbers.

E.g there’s a definite motivation kick to drink less when I see what it does to my hrv and sleep trends for days afterwards, while I don’t particularly care about the numbers being all that accurate.

Edit: Oh and turning on afib history in your Apple Watch will make it record like 10x data points which also helps with that. Maybe
