Open door calibration distance (GDOv2-S)

GET http://{deviceHost}/number/Sensor%20calibration

Returns the calibrated distance value used to determine when the garage door is open. This
is the known distance from the ceiling-mounted sensor to the rolled-up door panel (or to
the floor/roof of a car parked in the garage).

The laser range sensor compares live readings to this value to determine open/closed state.
Readings within a tolerance margin of this value are considered "open".

Available on GDOv2-S models only.
