After long research I have come to conclude that Nuki is not compatible with 2 wires digital intercoms.
All Bticino, Tegui and Fermax 2 wires are not in the list of compatibility.
Does anyone know if Nuki is planning to update something to make it compatible? I understand that most new buildings will use 2 wires digital intercoms and will be good to know if Nuki has intention to adapt the opener.
We did, I hired an electrician to do it. And with the help of an electrical tester, he managed to identify the component that opens the door, basically the opener in the board.
