Thank you for your brilliant feedback Georg! To be frank I did not know that there was a “Standard” intercom model that could be selected, so I went ahead and reconfigured accordingly.
I tried Connecting the basic wires (without red, orange and black). The intercom works, Nuki though does not open the door. That being said this is what occurs.
If the doorbell rings, the video will start playing in the little intercom monitor. Using the Nuki app and selecting the Open command, the video feed will cut off once “Open” is pressed, but the buzzer does seem to go off with the Nuki. Any feedback would be much appreciated (I am quite determined to get this working)
