Generic bus
Wiring looks good. But you had a good point before, maybe your system needs to be activated on use, and so you have to ring, before the setup.
Are you sure about the wiring because in the generic umet bus setup the purple and blue wires are not āneededā but anyway the circle is spinning and I canāt complete the setup - I will try it when my better half gets home, she will ring 
Then I would say, take out the blue and purple wire, and try without them! Blue is opening and purple is gnd1, and are mostly important for analogue setups!
Hi Pascal,
did you manage to setup your opener? I have the same model and looks like I have the same issue. I have setup wires like I was instructed in the app and cant get it to work.
I didnt use yellow wire.
Did you solve the problem? I have the same Urmetā¦
I followed instructions in App (1172 - there 3 or 4 varinats but always same wiring shown)ā¦also tried generic bus, it is also the same wiring like for 1172)
In my case it is needed to ring before you can react/open door/speak. But nothing happensā¦
