A small housing to contain a cheap NodeMcu copy and a single relay. This is mounted in my garage to recieve a signal for my OpenHAB installation to both control the door and report weather its open or closed.
This project was based on this:
The lid is held on by a single screw in the center and lips in the lid hold the boards inplace once closed.
Update: 4/30/18 - Revised lid so that it can be removed while wires are still connected.
