As the instructions said I wanted to do the basic setup, but I had no success. Here is what I tried:
Black cable --> BUS- and Red cable --> BUS+
Black cable --> BUS- and Red cable --> BUS+ and Orange cable --> BUS+
Black cable --> BUS+ and Red cable --> BUS-
The phone is inactive until someone rings to the flat at the main entrance. For this reason I cannot follow the instructions in the app to press the door opener, because nothing happens. I tried to ring the phone before the app ask to press the door opener. It sometimes worked, the app went to the next step, however the Nuki cannot open the door. Sometimes when the Nuki gave the opener signal, some weird noise came from the unit at the main entrance but nothing else happened. Also in this case, the phone stopped working, there were no audio signal, it seemed that Nuki took over the control totally.
Since its a digital system and it has only BUS- and BUS+ I dont know what else I can try? What instructions should I follow if I want to solder the Nuki to the opener button on the PCB?
Are not intercoms what have to be activated (someone rings) for working, at all incompatible with the opener!? I think to remember, that I read that often, as I sorted out my issues with it.
No, I have a other system, but you wrote for your system, that the phone is inactive until someone rings, and that sounds strong you have a system what have to be activated on use, and for such systems the opener cannot work.
I’m contemplating on how to wire the opener for a Codefon in a condominium.
There are four wires coming from the street. The BUS + and BUS - lines are obviously annotated. The other two opens the gate downstairs by pressing the button - probably shortening it. There is a mechanical switch detecting whether the phone is picked up or not and there is a single button to open the gate of the condominium. The voice is transmitted to the phone through a phone cable connected through a simple phone interface. The jumpers select the condo. Mine is 15, so the lower four are short.
When the phone is ringing, the users is supposed to pick it up and talk to the person downstairs. Upon deciding to open the gate the user should push the button which activates the opening mechanism. Pushing the button multiple times would activate the opening mechanism over and over again.
Now I try to relate this situation to the Nuki connection diagram.
By connecting the Bus wires (black, red, orange, green, yellow) as per the documentation I have concerns how the device would force the gate open. There is an obvious possibility to wire the blue and the purple wires for explicit opening, but this provides limited automation possibilities: supported in case of an Other door style setup.
Interestingly, there is a dentist’s edition of the circuitry with an additional connection for the door opening. They also provide an extra switch in their store for making the device automatically open the gate when a ring comes in. So that is kinda an implementation of the continuous mode. However I don’t think that would be compatible with the current Nuki Opener setup.
Are there any ideas about how to deal with this situation? How would you wire that?
