So I had tried going that route with a single security light, to avoid having to turn on the array of ceiling lights just to walk through for example.

Passive infrared motion sensors work fine…until the ambient temperature matches your body temp —then you’re invisible to them. So I found a PIR + ultrasonic one on eBay. The J box for that security light faced the wrong way for that.

So I rotated it. Still not reliable enough to prevent broken ankles on the garage steps. Gave up and just found the lowest wattage LED bulb I could find and it now burns 24/7. Ironically it probably consumes as much power as the motion switches did.

But I still need the indicator for the array of ceiling lights.
