I have installed Nuki opener on elvox 900-902 which works. The only issue that I am having is that the bell supression doesn’t give me the required behaviour:
I have 2 entry panels at the building entrance (2 doors in series). When Ring-to-open is activated, the first door opens when the first bell is pressed, second door opens when second bell is pressed. However this does not work any more when the ring is suppressed. Only the last door that actually has ringed opens, whichever bell is pressed. It feels like the module that opens the doors does not switch doors if the bell doesn’t ring. Anyone else has the same issue? Possibly I could fix this with an additional resistor to ground with wire coming from the bellbutton in order to make contact eith ground when bell is pressed so that doors can be switched. Alternative, can this be fixed in the nuki opener firmware?
Believe I have setup below. Wire 6 needs to be connected with 3 when ringing to switch to the other door.
