This is a very good little motion sensor Im using with Home Assistant to switch on and off a light in the downstairs bathroom. It connected to my Zigbee hub instantly and has worked flawlessly since I installed it. Simple, small and long battery life (obviously depending on how often its triggered).

This motion sensor does what it’s supposed to and does it well. I run it using Zigbee2MQTT on Home Assistant, and it integrates seamlessly. The detection is quick, the cooldown is around 30 seconds, and automation triggers are instant. It uses AAA batteries, which I really appreciate—easy to replace and longer-lasting than coin cells. I love Third Reality products and have many of them in my setup, and this one continues that streak of reliability and value. Solid field of view, dependable performance, and a great fit for any smart home.

Giving it 5 stars because it worked out of the box with the echo hub, no messing around. 1 to 2 second routine responses on movement.

I could easly add the sensor out of the box to Smartthings without any external driver. And it doesn't disconnect after a while like some other cheap brands. The batteries are AAA which is very cheap and can be found on the market. Only problem is the cool off time, that the moves are not detected one after another before 2-3 minutes. If you would like to trigger ligths or some stuff in very short time interval, this may be problem.
