yes, naming is hard. the gadget is not a garage door control but purely a mgarage door monitor. so the so called bypass is purely related to the monitor. the garage door control, if any, with its safety features remains completely stand alone. that to me looks like an ok architecture from the safety pov, where the gadget behaves as an eye and maybe a finger pushing the control remote, so the safety is delegated to the garage control. to state the obvious, I'm fully with you that there should be no override bypass inactive whatever on any kind of safety sensor, and the sensor should always be fail safe, i.e. if a sensor fails the motor stops, if an electronics compinent fails, the motor stops, if not locked shut it should be possible to manually completely reopen the door, etc. obligatory pointer to Nancy Leveson http://sunnyday.mit.edu/ http://sunnyday.mit.edu/
