Urmet 1130/3D Ring to open doesn't work

Hello,

i tried some of the solutions here in the forum, but couldn’t get it done properly. I then switched back to the wiring suggested by Nuki, so can use it over the app.

This is the look after opening:

This is how I have to connect the wires:
red → 1
violett & black → 6
orange → 2
green → 7
blue → 9

I can open the door via app. Somehow I can hear it ring via the speaker infront of the house

Any ideas what I can try?
