Hi i am from germany and trying to connect the opener to my video intercom have a nuki opener and a easydoor vm40 intercom.
I think it is a digital one (bus).
I did a littel research and find out that this intercom have also a other name (DT24) in Germany from the Company eurosklep.
I tried to connect the opener to the intercom where i connected black from nuki to (black/red) from the intercom and also the red from nuki to the (white/yellow) one from intercom. But when the Applikation says press the knob to open the door then nothing happens any more until it says timeout.
