Thank you for your response! I really appreciate that! Could you tell me please how can I update firmware of my intercom? I’ve tried to google that but found nothing. And how can I check the diagnostic buffer?
I have this same model 1133-D001 like Baptiste Jn (and Nick111 apparently).
The thing is, the terminal board on the PCB has only two screws on two connectors! No VA wire, only #1 and #2 connectors.
Two wires are connected together on #1, while two other wires are connected together on #2.
I measure constant 22VDC with a voltmeter between these two connectors, all the time.
But the opening button on the interphone case is able to open the main door downstairs only if someone rings the bell from the intercom panel in the street first.
However I don’t understand Yohannkazz’s message above as he points to a solution involving models that have 3 connectors (including the VA wire, which is absent from the model described in this thread).
Please, if someone managed to make this 2x2 wire URMET system work with Nuki Opener, tell me how.
Doesn’t it not working at all or at least you can open the front door? I my case I could get “Ring to Phone” mode to work but it takes to ring the front door two times in a row with a little pause. So first time I ring the front door it kinda wakes up my interphone and then the second time I ring it opens the front door as it’s already woke up.
