Hi, I just bought Nuki Opener, but I am having problems getting it to work with Urmet 1133. I have tried different Urmet configuration and also Generic analog, outcome is always same, when openers blue wire is connected then keypad outside of building starts beeping and door is permanently unlocked. Tried to find manual for Urmet and wiring diagram should look like this
1 Door phone speaker signal
CA Door phone call signal
2 Door phone microphone signal
6 } Power ground
10
9 Door opener control
maybe u are using the wiring for the 4+n version instead of the 1+n?
