My intercom (Koch VTC60) has a special button (the circle) configured to open my garage door. Would be nice to somehow have Nuki Opener offer an API / URL call to trigger these custom button. As a developer myself I’d happily help and even pay for such a convenience feature.
Can I ask how you got the opener set-up with the Koch VTC60?
I am following the instruction but I can’t finish the configuration cause it won’t open the door 
Attached my wiring
