Is there any smartwatch which allow me to selfhost
I would like to use a smart watch with health tracking (e.g pulse, steps, sleep tracking) but I don't want to setup an account and send my data to a proprietary cloud.
Can I sit host 'tge cloud'.
If not, can you recommend any watch which i can just sync data from watch to my Linux laptop (again: no account, etc)
The open source market for smart watches sucks. Gadget bridge doesn't really work for any "new" (i might be wrong here) devices.
Luckly Garmin watches are top notch and the software side its pretty good. You can not install the app and manually download all activities files via USB if you like.

Most newer Garmin devices should work since 0.82 (and earlier with nightly). It's not feature complete compared to using Gadget Connect but should be enough for most use cases, unless you really care about the social/awards aspect and some of the deeper metrics (although if you're handy with SQL you can handle that yourself).
Not being able to set an event date and have "daily suggested workouts" follow that is my only annoyance, although I've been happy just using the defaults for now.
