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

I use this in my main bathroom to turn lights on and off and adjust the brightness based on the time of day. The Zigbee sensor is tiny; you don't really notice it.

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.

Love these little sensors. This is the sixth one I’ve bought so far. I’m using these in Home Assistant and it was super easy to pair and put to work. I do wish that they had “normal” batteries that I could pick up from the local store but I also haven’t needed to replace them yet either. I just used an automation to tell me when the battery hits 30% so I have time to order some. The polling/refresh rate isn’t the fastest but my applications don’t need it to be.

fast response

Bought a couple of these to use with Home Assistant. One paired and works great so I set it up where I needed it. The other paired fine but only triggered once and then seemingly just stopped working so I decided to see if I could pull the batteries out and restart the device. Well to get the batteries out you have to remove the bottom cover and then (in tiny print) it tells you to level a specific spot to pull a little container that houses the batteries out. I tried a small plastic pick, a screw driver, a pocket knife, nothing was working so I applied a little more force and the plastic battery tray started to crack. After a little more convincing the tray came out but now it's broken and the plastic on the bottom of the sensor is misshapen. Why in the world would you not just make the bottom screw on our at least make the battery tray rotate to lock into place? Having to pry it out and ultimately break the thing is ridiculous. I did manage to get it back together and the status light came on, it showed triggered once again turning on my lights and hasn't worked again since, so the whole battery struggle was for nothing and now I'm stuck with a broken sensor that I'm guessing I can't retrun...

works great, i have them all over my house for lighting

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

Sometimes the simplest sensors are the best. Great for bathrooms.
