Serenity Doorbell Sensor
This is an ESP32-C3 based board that can detect up to two doorbell signals from a traditional doorbell. This runs in parallel with the existing doorbell, and can sense to the a/c signal from a button press. Since this uses power from the doorbell transformer it can stay always on and connected which lowers the latency in pushing a signal out.
