Hello, I am planning to interface my home intercom with home assistant through a Sonoff SV, but I really need your help because I have never opened an intercom since yesterday.
My intercom is a Siedle HT 511-01, I found a PDF containing the schematic (page 10) here:
I have a Sonoff SV with the Tasmota firmware and Home Assistant running on my RaspberryPi 3
I attach also a picture of my intercom opened and of my buzzer, as soon as I know the model I will write it here, but on it it’s written 8V - 6V
My goal would be that when someone rings the bell i receive a notification and then I can open the door through HomeAssistant
Do you think it’s doable? Can I connect the buzzer to the GPIO14 of my Sonoff SV and then open the door throught the relais of the Sonoff SV?
Thank you very much in advance for your support!!
