garage-thing

A WebThing for a Raspberry Pi based WebThings system which operates a garage door with a relay and shows the door's open state with a reed switch sensor, both connected to the Pi's GPIO ports.

The garage-thing is a Java based service running in the background. It is added on to the WebThings Gateway running on the same device (or another device on the same network) and operated through the Gateway.
