Opener not working with TCS ISW 3030

Hey,

i have the TCS ISW 3030 (TCS Audio Innenstation 5Tasten freispr. ws ISW3030-0140: Amazon.de: DIY & Tools). I know its not supported by default but i read that it works for the most people. The only problem some people had seems to be ring to open… but as i dont need it (i just want to open the door via the app) i want to give it a try.

I wired the opener with the intercom as in the nuki manual and as in many pictures from other people.

I have the following problem: The Opener do notice when i press the door buzzer. It does also notice when someone rings outside. But the opener isnt able to operate the door opener “buzzer” at all…

I wired the opener as in the picture:

This is the “easy” setup… I tried the advance one that should work with ring supression as well with the same result.

Does anybody has an idea?
