1 year ago - when sensor detect something (proximity)
- send message parking spot occupied
- turn on red light (closed loop)
- if charging button pressed (and sensor detect something), blink red light for 10 seconds (then again static red)
- when sensor detect nothing
- send message parking spot free
- turn on green light (closed loop)
- use a mqtt queue, 1 topic per sensor (2)
