I also have a Urmet, but it is a 1183/5. It only has two wires to"Line In" terminals. Although the picture from max is a different version, his yellow wire is positive and the white wire is negative. I have tried several methods to connect the opener as an “unknown” and generic. Before I go any further with it, is there any basic way to get it to work in even the most basic way yet? If not, can you provide a timeline in which there will be a solution? It makes little sense to be able to open the apartment door with the Nuki 2.0 lock, but not the building door. Also, I read in the document that one solution was to wire directly to the button. On the 1183/5, the button is a piece of plastic that when pressed, pushes down on a switch on the circuit board. Looking at the circuit board, there are four contacts on the back side. I have considered soldering leads of of the contacts to be able to check polarity while pushing the button. This is a last resort, since it may still not work anyway. Before I spend anymore time on this for now, I was wondering if you could give me your opinion.
Thank you in advance,
