works well
easy setup and does just what its supposed to do. Got this in the b/Friday deal but still good price. Long detection distance got it set up in the hallway and picks up motion straight away from opening front door which is about 18ft. Great automations with other devices i.e. lights works instantly (am using with Zigbee) Defo recommend will be looking at more from these guys.

Not the most reliable
Works, sometimes. Isn't very accurate or quick to detect.

Best Zigbee Motion Sensors I have used to date
Why did you choose this product over others?: This is the best Zigbee motion sensor I have used to date. The 2 AAA batteries, ensure that it has a strong connection to the zigbee router. It will stay powered for a long time due to these batteries. I have had multiple issues in the exact locations these motion sensors are in when using the sensors with coin batteries, but now These have not lost connection and have been very reliable. Super easy to install. The only dislike is the design, as they are quite Long, but that is needed for the AAA batteries so it is a trade off.

Fails to stay online fo any length of time
Works great for a short time, then becomes unresponsive. Keeps disconnecting from echo 4 Zigbee hub. Constantly resetting it

Really good little motion sensor with long battery life
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).

A nice unit...
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.

Great if you get it for sensible price of £12
Can't fault it after a few weeks use. Does the job.

Basic, but works well
A good waterproof motion sensor. It doesn't have light or temperature sensors built in but for basic motion detection it works well. It could do with some sensitivity controls, but doesn't have any. Works well with Home Assitant, so overall happy with it, but will keep looking for an outdoor presence sensor instead. Very good basic outdoor motion detector.

正常に動作しています
反応も良く、センサーとして役立っています 商品説明の通り、ジグビーハブかECHOスピーカーが必要です

Bisher Zuverlässig
Weil wir ständig das Problem wie viele andere hier mit der Kombi Alexa / Philips Hue hatten man den Skil immer wieder neu einrichten mussten sollte eine andere Lösung her. Im Gegensatz zu den Hue Sensoren Preiswerter schnell mit einen Echo gekoppelt und seit her laufen inzwischen zwei dieser Sensoren Zuverläßig und Schalten das Licht ein und aus. Was mit den anderen oft nicht funktionierte.
