I have in the main moved away from PIR's as either set off by trees moving in wind or local cats, or not activated at the most inopportune moment and one is plunged into darkness with a both hands full of shopping on the steps at side of house. Not knowing where you can put down shopping to get phone out and use phone as a torch.
So a mixture of smart bulbs, switches, and socket adaptors with timed or dust till dawn options plus being able to switch on from phone before I leave the car.
I still have a couple of PIR's but not really used.
Theory is great, passive inferred comes from some heat source, so trees moving should not set it off, but they do, possibly masking or unmasking some other source, a warm house some where. But to control a large area it would need multi PIR's as increasing sensitivity means they are triggered by things you don't want to trigger them, like neighbours central heating flue, or another lamp.
We loosely call them PIR's but in the main they also work with white light so don't switch on in daylight, so a PIR for an intruder alarm is not good. You can get smart PIR's which link to other smart devices, and also there are often user settings, amount of day light to inhibit turning on, sensitivity, and time delay. But it depends on how much you pay.
