Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.
-
No low-effort posts. This is subjective and will largely be determined by the community member reports.

A good, no fuss, simple open source GNSS tracker with HR that is compatible with gadget bridge would go a long way. I just want something like a classic casio digital watch that tracks my runs and forwards the raw data for analysis on my phone or a self hosted service.
OpenTracks?
That's not HW, I need the bloody HW to do any actual HR tracking. GNSS without HR is not worth much to me. There are no good HW solutions on the market, they either violate privacy or suck on a functional level.
OpenTracks has integrations with several HR BLE trackers: https://codeberg.org/OpenTracksApp/OpenTracks/src/branch/main/README_TESTED_SENSORS.md
And all of them are limited or require official app alongside of it. I repeat myself; there are no good open source (or just privacy respecting) HW solutions available.
That's simply not true. The Decathlon HRM Band for example connects to virtually everything that can understand a generic HRM over BLE. And limited in what sense? It's either sending a heart rate or not.
It doesn't track with GNSS, I don't run with my phone.
You may want to look at the supported devices on this project. It's an app to get data to/from wearables.
Two of the supported devices are bangle.js and bangle.js 2. These are open source smart watches with GNSS and HR, which have different apps available already that I believe can record data without your phone connected, and then sync later, either to your phone or computer (not sure on that one). And you can develop your own apps too of course.
I don't really know much more than that. I do want to get back into exercising regularly, and would like to track my progress, so I may get one myself at some point.
I've already looked into gadgetbridge, but all supported devices unfortunately have fairly limited functionality. I get that it's the premise with the reverse engineering they do to make things almost work.
The bangle.js models are a fucking ugly apple watch clone, I'd never wear that thing. And I'm not looking to get an actual smartwatch, I have no need for any of that clutter or a desire to charge my watch daily or every other day.
I've used a coros pace 2 for a long time, definitely not private but very limited smartwatch bullshit and >week of battery with +1h of daily GPS tracked running. Not supported by gadgetbridge though.
