Installed via HACS, 110 Entities, none available but connection via REST

[SchorschKloni]

Sorry for the title. Wanted to put all info in it :)
I installed the integration via HACS.
Added
goecharger: chargers: - name: Garage host: 192.168.1.130
to my configuration YAML and restartet HA

I get one Device with 110 entitities. But none is working.
Having a Home plus
With enabled V1 and mqtt (but nothing walks into HA)

So after X tries i asked chatGPT.

It gaves me a configuration via REST
With this i get some parameters correctly ito HA.
So the conection must be there.
BUT as a young child (which i am not :D ) i wanna have it working with this big integration.

Could anyone give me a hint how i can get it to work?
Or is it outdated?

Thanks a lot
Marina
