No problem! The nuki support is very good but unfortunately it seems understaffed!? But in the meantime, I helped to wire many different intercoms to the opener (even often models what are not officially compatible, and even where the nuki support tried to help but has given up in the end, we found still a functioning wiring), that it is a little hobby now! So, when I look at your intercom inside, it is to see, it is a analogue intercom, but wired digitally, because you have on every screw a second wire, what is not normal on analogue, just on digital, so I think they wired it hybrid!? So let us begin to sort some things out, please take a short isolated wire and take some isolation off from both ends, now hold one end on one of the screws and the other end on a other screw, and when the opening mechanism goes off when you hold the wire on the right two screws, you found the right two screws for opening, - please try this in all constellations and so long until you found the right two screws for opening (is easy and fast to do), then notice the numbers of these two screws and write again here, and we go to the next step.
