some questions as I couldn’t find any manuals showing a detailed wiring description for the Opener.
As our door system isn’t supported (Elcom bus system), I disassembled an old Elcom intercom with a physical button for the door opener and a potential free relay contact that get’s closed when the doorbell rings.
I hope that I can connect the Nuki Opener that way.
The button to open the door connects just 2 pins on the circuit board of the intercom.
Can the Nuki Opener close a relay (or maybe already provides an potential free relay contact) to simulate the button-press?
If I need an additional relay, how high would be the output voltage of the Opener?
And how can I connect the potential free relay contact of my intercom to the Opener,
so it recognized the doorbell?
Can I simply take the supply voltage of the Opener (will use it with USB Power) and connect it over the relay contact to an input of the Opener?
And if all of this is possible, whoch wires of the Opener do I have to use,
and what should I select in the app as model and brand.
Thanks a lot if anyone can help.
