AqaraZigbee Motion Sensor P1, Smart Motion Detector, Requires AQARA HUB, 5-Year Battery Life, Configurable Detection Timeout, for Alert System and Automations, Compatible with HomeKit, Alexa, IFTTT

Fast. Stable. Simple. Easy to connect. No cloud if you don't want it. I find the Lux sensors accurate enough to control lighting. The ping light is bright enough to cause a flash do you don't miss it if you need it and it's got great functionality. At about $20 it's a great buy. Smaller than you'd expect, it blends right in!

It's nice and small but works very well, it's able to detect motion right away and you can hide it out of the way since it's nice and small.

Easy to set up with Home Assistant via Zigbee. These are much better than the IKEA VALLHORN motion sensors. They react quicker and are smaller. The wife likes them better because when she walks into the closet, the light comes on now with no delay.

It’s a great sensor but it does not work through a window even though it was mentioned it would work. I needed something to look outside and trigger a light but since it does not work through the window and is not outdoor rated, I have to find a different use. Easy to setup and works in HomeKit.

The battery life advertised of 5-years is completely false. I have tried three of these motion sensors and the batteries died between 1 and 3 weeks on each of the sensors. Up until the batteries died the motion sensor worked great. Other reviewers have reported similar experiences and I can confirm they are correct if the sensor is used in a room where there are people to detect. If you install it inside a closet where the only motion detected is when the closet door is opened, the batteries will probably last longer. This sensor uses two 2450 lithium batteries that cost about $3 each so plan on that recurring cost if you want to use this sensor. But even if you are OK with the $6 battery cost, replacing the batteries is not easy and there is a good chance you may break the sensor trying to remove the batteries. This is because a a long battery holder cylinder has to be pried out to get to the batteries. These two issues make this sensor a bad choice. I have not experienced this with any of the other Aquara Zigbee sensors that I use so this one seems to be a bit of a bad Unicorn.

I bought this to use with home assistant. It connected flawlessly and responds almost instantaneously. Well made package and small size.

Favorite cheap motion sensor. Works well with Aqara hub. Much more reliable and performant than the “newer” thread/matter based one.

Worst design ever! it claims to detect 7m, but turned out to be around 1m! Also the sticker is VERY VERY tight, with residues, AND battery change? no way! you have to take the whole thing off then change the battery. I'm returning it. Aqara contact sensor is perfect. but this? garbage!edited: the response is not too bad since i switched to zigbee2mqtt. It's more responsive! But the range still sucks especially at corners
