TODO:
- correct speedfactor when moving at pwm=100 for some time over opaque+clear OR implement speedfactor for up and lower state
- implement failure detection (timeouts),
- has to stop when no sensor change detected for some time
- in classifySensorValue() only allow a certain time of unclassified reading
- has to stop when driving upwards (or in general) for too long (for example end marker missing)
- manual mover function should work better with iot commands (set position, no errors)
