I have an issue to connect my Nuki opener (with bridge) with my Urmet 1133/15. First, I can share the picture of inital connections, new connection with the Nuki and connection process I followed.
I can open the the door without ringing to the intercom IF the trigger (surrounded in blue on the picture) is not actived (intercom is unhook)
I can’t ring to the intercom with this connection. But, if I connect the 2 yellow wires to “CA”, the intercom can ring again. But, the Nuki can’t open the door.
Sorry, I was posting it to help you in case you wern’t able to get it working. Mine works perfectly, the only thing that doesn’t is that the doorbell at my actual apartment door doesn’t ring anymore. This isn’t so much of a problem because unless the neighbors need something, they never ring it. I haven’t been able to get this working, but the outside one works.
