+1 for Hue Motion sensors.
I have a bunch of the indoor ones and recently got one of the outdoor ones. They and the SmartThings multipurpose sensors are by far the most reliable battery-powered devices in my mesh. I’ve had a similar experience of the batteries lasting multiple years, too.
The response time when directly paired with a ConBee II is great, and I use them for motion lights in infrequently used rooms like bathrooms. The response time was lacking when connected to the Hue hub and having HA poll the Hue hub.
Every once in a while one of them will drop out of the network (usually when I’ve messed with something), and a quick re-pair has always fixed it. Examining the reported parent of the sensors via
zha_map shows that the sensors do sometimes end up with a different parent from day to day, but that doesn’t seem to keep them from functioning properly.
I have one of them in a shed located on its inside back wall, about 50ft from my house. Usually, the parent is one of my exterior lights on the wall of the house, but sometimes it’s a light in a room along the back side of the house. I’ve had more issues with the Yale lock on the door than I’ve had with the motion sensor inside the shed about 10ft further away.
If you’re wanting to buy the indoor Philips sensors and don’t want to wait for a sale/deal, the best regular price I’ve seen is at Costco, which is 2 for $60. Still pricey, but at least that’s a little better than MSRP.
