Hi Rose,
It was not a problem for me to wire the intercom in any way.
The current wire is done by following the official Nuki guide for unsupported devices.
Here is a schematic from a guide:
And according to that, I wired my intercom:
So, I have 2 incoming lines that are entering my intercom: red and black.
And I tried to wire it according to the Basic setup guide, but that is not working.
I also tried Enhanced setup, but that is also not working.
Thisis Enhanced setup from a guide:
If someone provides me with the correct schematics and device type that needs to be selected in a Nuki app, I am pretty sure that I can set up Nuki Opener without problems.
