Q: Is this notifier only?

[stomko11]

I have TCS intercom in my apartment and would like to use it for opening the door. Can this be achieved using your code, or can it only to decode message when someone rings the bell from main entrance? Anything changed on being able to use it via esphome?

My code is only for decoding the messages and sending them via MQTT. For information on sending messages check out https://github.com/atc1441/TCSintercomArduino I have not further tried to integrate with esphome since my MQTT approach works for me. :)
