KVV Binding - Karlsruher Verkehrsverbund

Hi , i was trying to get the “KVV Binding” for the support of the public API of Karlsruher Verkehrsverbund (public transport system in Karlsruhe, Germany) working, but I seem to fail miserably. I know, this might be uninteresting for the majority of the users here, as it is tied to a specific public transport system, but I would like to somehow troubleshoot. Anyone who could help me doing that ?

I understood in order to use the new API ( without required token) I installed the 3.4 jar file manually. I configured the bridge and the Stop Thing, but it would not generate a channel or does something at all. I Checked the logs, but the only indication I can see is it gets from un-intialized to online status and that’s it.
