I use the AmazFit Band 7, the last sensibly sized watch that exists it often feels like.
Weather fails to sync, but then it's probably the least important feature on a watch. The only feature I really wish Gadgetbridge could do that even the official stack can't is "nap mode"
As a narcoleptic person still recovering from major depression, I wish I could either press a button to silence the watch and set a "smart alarm" for 30 minutes. Even better if it would turn on automatically if it detects me sleeping during the day!
The only other thing GB can't do is stand in for the phone-side ZeppOS API functionality, but who needs that, let's be honest!
Fantastic battery life to boot. I have gone two weeks after forgetting to charge it while wearing it almost 24×7!
But, I now have Breezy Weather setup and working! I can now know how much it won't rain during the rainy season where every other part of the state is flooded with the flick of a wrist 🥲
