This is the case that I used to house and mount my Ultimate Garage Door Sensor.

It uses a Wemos D1 Mini and talks to my home automation system (home assistant) via MQTT. It uses two optocouplers to control the Garage Door. It also sense if there is any light on in the garage or if there is any motion. It reports back the temperature and humidity in the garage as well as if there is a car parked in the stall and which one it is in.
