Ist die machBar offen?
Ist die machBar offen? is a simple client-side JavaScript front end, which queries the
space-api of the CCC-P (https://spaceapi.ccc-p.org) and displays whether the hackerspace ("machBar") is open or closed.
The state.open field returned by the space-api is controlled by the IoT enabled "SpaceSchalter" which is located inside the hackerspace.
