Hello there,
I just kind of sorted out a solution with my Urmet 1142 Intercom. It’s not perfect but allows to open the gate remotely.
I solded a wire behind the PCB to be able to connect to the switch directly. For the Nuki Opener, I configured it using the “other door” setting. For now, I only can trigger the intercom when someone calls me or send me a text when they call, but at least, I can do it remotely.
See attached picture and detailed steps:
- Blue wire connected to the switch SW2
- Cut a little plastic part so the blue wire can go through without being damaged
- Connect the blue wire to the blue wire from Nuki Opener (I used a clamp) then Purple one to the “0” pin of the Urmet Intercom.
- Remove the plastic above the switch SW1: the opener cannot trigger anything if you let this switch done (pushed done when the received is present so you have to disable it).
Latest tries show that if I connect the yellow nuki wire to the white from the received (top left on the picture, connector with 4 pins), then someone calls in, it enables the auto open IF I disconnect the yellow wire AFTER it rang. Not sure why. If someone from Nuki see this message, let me now if you think of a solution. I will send you directly those details in the support thread I already started.
I will keep you posted if I find something more.
