Aqara Presence Sensor FP2+ Bracket, mmWave Radar Wired Motion Sensor, Zone Positioning, Multi-Person & Fall Detection, High Precision, Supports HomeKit, Alexa, Google Home and Home Assistant

Firstly, this device is Home Assistant & Alexa friendly without an Aqara hub. Secondly and very importantly, this is a presence sensor, NOT a motion detector! It detects a human body in a room. This means you can use it to keep a light on whilst you are in the room, even if there is little to no movement. It detects presence, distance [from the sensor] and light level in lux which can be shown within in HA. In the Aqara app you can see motion detection and light level and distance on a grid. Within Amazon Alexa you can see presence only [detected or not]. No light level or distance. I've set this up to turn on a light if it detects presence using HA. It works very well. It is almost instant. It isn't cheap, but if you want presence [not motion] to be detected, this is fantastic. Obviously this costs a lot more than a mere motion detector as there is more "brains" going on. Would I buy it again? Yes. Would I recommend it? Yes, if presence detection is what you need.

Works well but if there are two people in the room sitting still and one leaves it thinks the room is empty.

Bought this to replace an Aqara motion sensor that seemed to be a bit slow to respond. Detects presence quickly and accurately. I have two of these in my house now and they are both working really well with Home Assistant to trigger lights and give notifications.

Whilst I'm sure others will find this a brilliant device unfortunately for me I could not get this one to connect to my WiFi no matter what I tried. It would always fail at step 4 of the setup process. I tried multiple times across 3 different devices even changing my WiFi password to ensure there were no special characters in it but still no luck. Therefore since the device would not set up, it was pretty useless to me. Edit: Aqara did reach out to me to offer a refund for the item once they read this review about it being faulty so there is that at least.

Might be a good sensor, but it’s annoying to setup. Too finicky and does not even register half the time. If you put it in the corner of the room or have a lot of stuff, it constantly creates ghosts.

Many reviewers have already referred to the following deficiency: When I leave the room where the sensor is placed it frequently takes many minutes for the sensor to acknowledge my absence. On many occasions the sensor registers 2 people in the room even though there is only one. The product isn’t fully developed. I can’t recommend it.

Excellent reliability and accuracy! Onboarded using Aqara app (no hub required for this) then linked to Home Assistant via the HomeKit integration.

This is great at what it does: DETECTING HUMANS. If you have pets, don't buy this as you will have false detections all the time with lights left on.
