THIRDREALITY Zigbee Motion Sensor 1 Pack, Zigbee Hub Required, Pet Friendly, Works with Home Assistant, SmartThings, Aeotec, Homey, Hubitat or Echo Devices with Built-in Zigbee hub

I've had a few different brands of motion detectors and this is the best so far, best to spend the extra money. The cheaper ones can be more trouble than they are worth.

Integrated really quickly with Home Assistant/ZIGBEE2MQTT.Hidden away nice and easily as its quite slim (but is tall)Never had an issue with drop-outs or disconnects.. Responsive...Recommended..

This switch is handy you can put it anywhere in your house and it control various devices to switch the lights on in all the rooms the good thing you can apply these switches right by your bed say if you want to go into the living room you can switch the light on from your bedside and vice versa depending where you site your devices they work through a program called home assistant their are many options you can use them for still setting various up at moment but overhaul good product

Didn’t do as advertised had to send back for refund

Good sensor , responsive, but not worth £30 for a standard motion sensor ,£19 two weeks ago now £30 I’ll wait before I buy any more , and they put the price up again !

It works with HA, it's nicely made, it paired smoothly... but it seems shorter range than my old SONOFF one. That said, it's much better made than the old one, it uses AAA batteries rather than lithium ones and I really like it. It's just a shame it seems shorter ranged! I'm getting maybe 5-6m from it, whereas my old one did a good reliable 10m.

Ordered 4 sensors. Very easy to pair with zigbee2mqtt. 30 sec sleep. 3 sensors have firmware version v1.00.33 and 1 sensor was on v1.00.37. zigbee2mqtt provided the option to update v1.00.37 to v1.00.58.There is no option to upgrade v1.00.33 version

I bought 2 ot those, the first one actually connected to the Echo Studio for few days and then stopped connecting.It was pretty good while it lasted.The second one did not connect at all, I tried putting it in pairing mode and asking Alexa to find new devices like 20 times, in-between factory resetting my Echo and bunch of other stuff - nothing helped.Edit:It does work with the hub, and does work with Echo studio after using the hub to update the motion sensors firmware.Now I have to return the hub.
