Possibly the issue was they used PIR/ultrasonic (aka dual-tech) sensors and the ultrasonic one was picking up vibrations, I’ve seen that happen in tenant spaces before and turning down the ultrasonic sensitivity fixed it.
I run electrical work and if I was asked to install these, I would’ve written a sarcastic RFI to make sure the customer actually wanted to do something this stupid and expensive vs a $2 nightlight in a receptacle.
