I'd like to set up exterior lighting scenario wherein the exterior lighting is on at 20% between dusk and dawn using a timeclock-triggered scene, and then use motion sensors to trigger zones to 100% via contact closure when motion is detected in those areas. This seems like it would be a very common scenario.
I've seen the App Note regarding motion detectors, but it must be fairly old as the sample vendors for the motion detectors are all out of business.
Is this a common scenario? If so, what exterior motion detectors are commonly being used?
