Considering building my own ESP32-based door chime instead of spending almost €200 on the “DoorBird IP Door Chime A1061W”. I can probably buy all required components for less than €15.
#DoorBird sends local UDP broadcasts and the encryption scheme is publicly documented, so it should be straightforward to receive and parse those packets on an #ESP32. And then, depending on which doorbell button was pressed, simply play a sound.
