After a lot of trial and error I managed to wire the opener to open the door. However ring suppression or ring to open doesn’t work Does anyone have experience with this model? or can help with the wiring? [k3] So far it looks like this: 3 - BLACK 4 - ORANGE 5 - PURPLE 6 - RED 7 - empty 8…

Oh wow!
Thank you for the reply. I did some more digging and found this thread.

Now I’m waiting if the Mono Amplifier solution works. Otherwise I’ll try yours.
