The original software on these is really bad. e.g. if move between time zones during the day then Mi Fitness app most likely won't get all data out of device. Also Mi Fitness cannot download data of previous date out of the device. Steps counter is also very bad at keeping track if you move slowly e.g. in your apartment.
Is there a good fitness band to measure sleep quality that lets you download the data from a Linux machine, or at least lets you see the data on screen?<p>With "see the data on screen", I mean at least some quality index, not just the number of hours you slept.
I'd love to see a full featured open-source firmware for the Mi bands, as the original firmware requires an device-specific Xiaomi-issued key for Bluetooth pairing. For obtaining this key you have to use the Amazfit App with an Xiaomi account at least once. For details check out <a href="https://gadgetbridge.org/basics/pairing/huami-xiaomi-server/" rel="nofollow">https://gadgetbridge.org/basics/pairing/huami-xiaomi-server/</a><p>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.
I just need a way to download the data on my PC so I can keep a backup, since I had to switch 2/3 apps to keep using the Mi Band since 2015. I have 8 years of sleep/steps/heart tracked and no easy way to export and visualize the data.
An open source(ish) fitness tracker would be great. I like the idea of being able to write apps for my Apple Watch to add custom features (I.e. automatic rest timers when weightlifting) but don't want a smartwatch or soemthing with that small of a battery. A WHOOP that I don't have to pay monthly for and can get some programmability out of would be great
Oh neat. I've got a handful of these things. They're cheap enough that when the band breaks or the screen gets a decent scratch you don't feel bad just buying another one.
