Hi, has someone managed to connect to Comelit 2622 - I have only S and 4 connected whil P2 and C2 are not in use?
Hi! Without a photo of the momentane wiring, you will not get much answers. Please provide a photo.
Hi! Sorry for the late response! Yes should work, looks like a standard digital bus system, - the colour/white bus-cables are very common, and is very standard! Let me know, if you need further help!
Beginner here: I have managed to control the release of the door and garage buttons of the 2622 with my Arduino. I now want that to trigger a different action inside HomeKit. Anyone have clues about how I might be able to sense when the buzzer gets pressed ?
