Intercom with touch sensing button (Comelit 6721)

Hi all,

I am currently trying to connect the Nuki Opener to a Comelit 6721. I’ve allready read in the nuki developer forum that Comelit intercom systems using Simplebus are not supported (even not in future). So my plan is to connect the Opener using analogue signals.

The main question is now: how the capacitive touch button (door-opener) can be actuated by the Nuki Opener? Does anyone ever did something like this? Electronic skills are present but anyway I’m not really familar with such capacitive tuch technology.

Many thanks in advance for your support!


Hi did you manage to find a solution?

Did you manage to connect the NUKI OPENER to a Comelit 6721W/BM?
