I have installed Nuki opener on my Intercom Koch TC30 and have an issue with “Ring to open” function - it doesn’t work… When I ring having “Ring to open” activated, then the ring in the apartment ring, but has a strange interruption after 1 sec and, of course, door is not opening.
Hi Yev
Did you get it to work? I also have a Koch TC30 and can’t get it to work. The first try with Green/Orange in A and Black in B and Original A connected with Yellow/Red doesn’t work at all, that way not even the original intercom works anymore.
The second try suggedsted by the app ( Black in A and Green/Orange in B and Original B connected with Yellow/Red) keeps the intercom working and Nuki recognizes the door bell but doesn’t open the door.
