Hi there,
I’m in the Uk and have a wireless doorbell receiver that plugs in the mains. See pictures
I am wanting to see if I can use an esp32 to send notifications via ESPHome on home assistant. I don’t know the best route, but could I perhaps intercept current going to the speaker which triggers when the doorbell is pressed? And could i power an esp from the receiver PCB if the voltage is within the right ranges?
