Tcs isw3030

Hi,
I just get a new intercom installed by my landlord. its an TCS which is no longer supported, so i wired it up as a “Generic” Bus device (Koch)
Original Setup


Wiring according app and instruction for generic bus devices:

I followed the instructions in the app but I get stuck during setup at this screen. I press the opener, i hear that it opens the door but the app doesnt recognize it.

I reset the door opener, i changed the bus cables around, i dont know what else to do.

Any suggestions?

Thanks,
Christoph
