The fridge door sensor in G1 is an ESP32-S2
Software and 3D printed parts: https://github.com/edinburghhacklab/fridge-door-sensor
The 3D printed parts for this are:

- post (on the door)
The sensor is a standard end stop limit sensor with the connector removed and some resoldering to align the holes properly.
