I agree, most people assume they know more than a manual and try to figure things out on their own. In this case it seems most people were not reading how the sensor would load and unload with the switch turned on causing all the headaches. Such a simple solution!
When buying a sensor or motor on the job, the first thing that I do is read the instruction manual for correct wiring and setting diagrams, but when I buy a component for the house, I figure that I know better than any manual. Sometimes the hidden items like the auto load function are worth the read.
