See: https://community.openhab.org/t/new-binding-opengarage-controller/78750 for the openhab forums post.
I’ll try and add channels for vehicle detection over the weekend – I don’t use this as we have a 2-car garage with a single door, so I have the opengarage centrally mounted. I guess I could move it over above one of the cars for testing purposes.
For the temperature readings – this is only supported if there is an external temperature probe connected to the controller. Perhaps I’ll order one just for testing reasons.
