@s00500 I have no idea how to push things into the PlatformIO registry... :)

Does it pull releases or a specific tag?

So basically the 2 info files in the repo needs to be set and then we need to make a release, I am currently in Amerika with very limited time and internet till in 2 weeks... but if we should try to make a release let me know

Usually the registry picks up the new tag and updates itself

Hi Lucas, let's try to get this done.

I believe library.json is fine, but presumably you need to push the update to PIO.

Publishing¶

You can publish a library to the PlatformIO Registry using pio pkg publish command. Every time when you modify a source code of a library you will need to increment the “version” field in library.json manifest and re-publish again.

Ok all so I think it was actually the keywords being too long as the main issue here... not sure though, it is published now anyway, I will keep the registry updated on every release from now
