Interesting…let us know on your testing update.
On the motion sensor I’ve used a small short piece of PVC tube to limit the detection angle down to 5 degrees or so.
Placed the motion sensor across the driveway aimed at a wall on the other side with nothing that will cause false trips.
This is acting as a laser sensor.
At night anyone crosses the driveway our bedroom Alexa says, “Driveway detected motion”, turns on a floor light in the living room and makes a dog barking sound for 2 minutes then turns the floor light off.
It’s been working like a charm…no false trips !
