WOOLLEYZigBee Motion Sensor, Wireless Mini Motion Detector Sensor Detect Motion Send Alerts or Trigger Lights to Turn on, Batteries Included, Zigbee Gateway Bridge Hub Must Required

Simple and easy to install with an appropriate zigbee hub. Decent performance for price. Has a minute delay time built in after motion is no longer detected to when the system reports no motion.Would be nice if it had a light sensor (but I knew when buying).

This zigbee sensor is quite small, with the base being just big enough to hold a coin battery in it - you couldn't go smaller without a smaller battery. It seems plenty sensitive for internal use.I paired this with Zigbee2MQTT without hassle, though interestingly it's reported as a SONOFF SNZB-03.There are no settings you can write back, such as sensitivity levels, timeout lengths, and the until only reports occupancy and not illuminance like many others.In the end I bought a bundle of visually identical by functionally richer sensors direct from China, and for less too. While this unit isn't bad, there are better options if you can wait for postage.

Good value but I had to set up in one app the tell another app how to use it

Purchased x2 sonoff motion sensors and a moes wirless hub , never workedOrdered this and paired with echo zigbee hub and just works

Update after a few weeks. Awful. They have to reset once a day - have went back to the other awful ones that at least last up to 3 days before resetting. Avoid!

Tried but failed to pair this garbage with Alexa on my Echo: an hour of my life I won't get back.
