Great – It Works!
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.

Instant handy switch
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

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.

Good quality Zigbee motion sensor
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

Not connecting to Echo Studio ZigBee hub
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.

True to its claim, pairing with Echo 4th gen is as simple as “Alexa, discover devices”. The Zigbee dream. Once that was done, the device presented in Alexa app and has been easy to build a routines around it to turn nearby smart light on when activated, turn it back off after inactivity.As with most motion sensors, it’s designed to only trigger once, followed by an idle period of a few minutes where further events won’t be registered, so keep that in mind when testing your routines. Fortunately the Alexa app correctly shows when the most recent motion event occurred.I haven’t tested its sensitivity in detail, nor battery life, but after a few weeks of use, it does the job adequately for my needs and I’ll probably be buying a few more for more automation.

Spent multiple hours going through forums to identify a solution, but unfortunately not motion sensors are not connecting with Alexa

Guter SensorFunktioniert mit smart live App sofort. Unkomplizierte Einrichtung.Einstellbare verzögerte Abschaltzeiten (2-5-10-20 oder 30min.)Nutze den Sensor für den WC Lüfter als Schalter ist ein sonoff zigbee mit Schalrelais im Einsatz.Vorteilhaft sind auch die Standard AAA Batterien.

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.
