This is great! I tried to do this because I wanted to add an indicator of my heart rate to Slack, so people would see if I'm pissed off, but I could never get the data from the ring. I'm very curious to see how the author does it.

#42I couldn’t find it on the product page: any idea if this has a vibrating alarm? I’m in the market for something to wake me up without disturbing my partner
Wouldn't a watch do that? Ex. the https://pine64.com/product/pinetime-smartwatch-sealed/ is dirt cheap and its alarms just vibrate the watch.
I guess it depends. My partner still gets woken up by my (smart)watch at the lowest vibration setting.

#43I'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.

#44The hardware is getting so cheap! But the software... I bought for $20 a bed lamp that comes with led lights, bluetooth receiver, clock and alarm clock, and wireless charging for my iphone. It has a microphone to stream all my conversations god knows where, though its purported purpose is to listen me sing and pulse the lights according to the pitch. It comes with a convenient app to set the clock and the lights. But…
You could try to open it (carefully, you might damage your precious lamp. Also please plug it out beforhand). Often times smart devices like these have debugging ports left on the board you can easily access with some clamps.

#46From the GadgetBridge pull request[0] mentioned by dingensundso:
There's a nice site with a lot of the BLE API documented (including commands) at https://colmi.puxtril.com/

I used the smallest fitbit for that. Work very well for me.

#49Earlier quoted context omitted.
From the little bit of research I just did before buying one, most people are reporting that compared to their more expensive trackers, the heart rate, accelerometer, and sleep tracking functionality are all pretty accurate (good sleep tracking being dependent on a high sampling rate, which decreases battery life), but the blood oxygen and "stress" reporting is uselessly inaccurate.
I tried blood oxygen and the readings were the same as my pulse oximeter (though it always shows 98%, so I haven't managed to test any other value), but my sleep reporting with the ring would regularly be three or four hours longer than I actually slept, making it useless.
> test any other value
Try this:
Hyperventilate for a minute or two. Then, make a full exhale and hold it. You should be able to hold your breath for longer than you normally can and during this time you should see the value drop a bit. Be sure to inhale before you start getting dizzy or faint. (Note: do not do this under water)

#50Cool. 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.
