Hello how i connect my intercom with Opener. I have only 2 wire from wall ?
Hi! Do you have a external bell? Or from where comes the sound when someone rings the bell?
Sound is from intercom earphon
Sorry, only with backtracing of the circuits of the intercom and soldering, because bell signal and voice signal comes over the same wire, so you can’t unscrew it for the bell functions because you would loose some other functions, but for the bell functions you have to unscrew it! Sorry!
Edit: you can try and follow the wiring for generic bus in the app, maybe it would work!?
