    Thanks for the detailed reply! I'm just a hobby dev and wanted to see if I can get my daily weight-ins from a smart scale somehow into Garmin Connect. I'm very new to the eco system. From what I gathered there is no API to just add weight measurements programmatically. Therefore, I was thinking of creating FIT files, since my current understanding is that  there is a dedicated FIT file type "Weight" just for that.

    I'm not affiliated with the manufacturer from my scale, and they're not in the list of manufacturers supported by FIT atm. I didn't know about the ANT+ membership. It makes a lot of sense that this is governed though, and I can't just "add" them myself.

    I've since read up a bit more and understand that FIT files are most often generated by devices, so having the SDK in low level languages makes a lot of sense. In my case, I wanted to write the FIT file in a web application, so either using Python or Elixir :D

    I think my new approach is to write the FIT file on my Garmin device instead, and have the file sync to Garmin Connect like other activities.

    I don't know if you are looking for a project or looking for a solution, but what you are describing already exists.

    Thanks! I know that solutions for this already exist. Most require you to provide them with your Garmin Connect credentials, due to the lack of public API, which is not great. I also don't necessarily want to sign up to yet another service necessarily. I'm aware of other tools that I can run myself and that would avoid these two shortcomings (from my perspective at least, other users might be perfectly fine doing the above). But yes, also figured it would be an interesting project to get some experience writing Garmin ConnectIQ apps.
