Yeah, just bought some for my upstairs and downstairs hallways. Don't think I'll bother using them in rooms I don't just pass through.I own 3 motion sensors and I only use 1. I'm very frustrated by them. Even if you manually turn on a light, as soon as the sensor sees you, the countdown timer to shut the light off starts. Or you can make it do nothing after the idle time, but then you have to manually turn off the lights if they accidentally get activated by motion. Having pets just makes it worse.
It just doesn't make anything more convenient except for areas that are exclusively passage ways. My one active sensor excels at being in the house's entryway/mud room.
I think there is a hue labs thing to fix that problem though.
Fake edit: "No Motion, No Fuss." If there's no motion, the lights go back to their previous state instead of turning off. Dunno if that'd work better.
