K4CG door-status

This program submits the k4cg space door status to "heimat". It is intended to run on an ESP8266 controller with micropython firmware. In the "hardware" directory, you can find a case design for OpenSCAD, which is suitable for 3D-printing.

It contains a JSON formatted structure like:

{"humidity": 35, "door": "open", "date": "2017-08-21 19:11:50", "tempDoor": 27}
