Exactly the reason I ditched it. It stopped auto-syncing data after some stupid android-app split. Like they have 3-4 apps? All similar, but supports different hardware.
In Mi Band 2 / 3 days it was working quite good.
With "see the data on screen", I mean at least some quality index, not just the number of hours you slept.
I would be interested to know if others have interesting linux desktop software or workflows for working with this data when it comes off your watch
Google partnered with fitbit last year and now sleep data and other biometrics are shared with the fitbit app. The good thing about this is that you can access your data via fitbit's API, there is a python package for this process: https://github.com/orcasgit/python-fitbit. You can read this article if you want more details on how to configure oauth to make this work: https://towardsdatascience.com/using-the-fitbit-web-api-with...
The cons of this setup is that you still need an android phone synched with your watch and is not too privacy friendly, but sure, you could run the code on your linux machine
Google owns Fitbit, and it’s not clear what the future of Fitbit is as a standalone brand or product line
They have an export/takeout form in the app, which will create an archive with all your info and send you an email, and they provide instructions to parse it (e.g. in Excel). They also have an API, but it requires setting up a public OAuth endpoint for authentication (for Web apps) or pre-approval (for Mobile apps).
If gadgetbridge wrote an oura ring connector id buy one in a heartbeat. I had a mi 5 and the data quality was so crap.
It is interesting to wear 2 of the same trackers, one in each wrist, and see if they are close to agreeing.
I do that with 2 Mi Bands.
The variance of a single point estimate is infinite.
While thinking about it, I wonder if that's even compliant with GDPR, as it forces users to provide their email address for no good reason.
Eg. The ESP32 has this feature.
I got an Amazfit Band 7 after my OG Bip died. More info as far as blood o2 and fitness recovery & VO2 estimates etc, but it loses the compass, barometer, a physical button (bizarrely imo) & a few month(s) of battery life. The OLED is certainly nicer in some situations (almost always indoors) but I very much miss the battery life. Oh, and lots of app & custom watchface support too.
Btw if you have a larger budget, Garmin is also apparently pretty good with good battery life and a very similar screen type (and much better sports tracking).
I tried I like Amazfit Bip (older, more contrast, low refresh frequency) and Amazfit Bip S (newer, less contrast, higher refresh frequency, music playback control) devices that work for more than a month on one charge. For Android synchronization one can use excellent FOSS Gadgetbridge app.
