THIRDREALITY Zigbee Motion Sensor, Pet Friendly, Compatible with Home Assistant, SmartThings, Aeotec, Homey, Hubitat or Echo Devices with Built-in Zigbee Hub

UPDATED BELOW I picked this up for $15.99 and so far so good. The sensor is about as small as it could possibly be and still fit two AAA batteries inside. It paired right away via Zigbee with my Hubitat C-5 hub and no other configuration was required (but see the little quirk below in the update). It does not have a tamper sensor. The only data returned by the sensor are motion and battery level. The coverage area is nice and wide and I was pleased to discover that the motion sensing recovery time is only about 35 seconds. Why does this matter? I currently have six Bosch motion/temp sensors in various places and one of them is right outside my front door. I happened to get those on some sort of weird flash sale for $30 each where they were normally about $90. For $30 they are just fine, but they are large, take 4AA batteries, and most significantly have a MINIMUM three-minute recovery time in between motion sensing events. I use one of the Bosch sensors to alert me when one of my two dogs has returned from whatever adventures they were having outside. They tend to do their own thing and one of them almost always comes back before the other one. If they return more than three minutes apart then it's not problem and I get two separate alerts for the two different dogs and can open the door twice. But if the second dog comes back during the three-minute window right after the first, the Bosch motion sensor won't pick up the new motion alert and the second dog will be forced to wait outside with no recognition from his owner. No big deal right? He just has to wait another three minutes. Well, no. If you are within the three-minute recovery period and the sensor is tripped again, it starts a NEW three-minute recovery period. Assuming the dog doesn't freeze to death and keeps moving at some point during that three-minute period, the sensor will just keep re-tripping and going into an endless loop of three-minute recovery periods until the dog finally freezes or dehydrates. Thus the dilemma. With the 35-second recovery period of this sensor, I have now reduced the potential mortality rate of my second dog to return home by a factor of five. Good progress. UPDATE: The first sensor continues to work great a month later. I bought two more via the two-pack deal. The first one paired up instantly with zero issues. The second one paired up fine but came up as (blank) for the device type (Hubitat C-5 hub) and very strangely showed "Signify NV" as the manufacturer instead of ThirdReality. I tried changing the device type manually to "Generic Zigbee motion sensor- no temp," which is what the other two sensors automatically configured as. The sensor would show up as a device in my Hubitat device list but would not report any data. I removed it, did a factory reset, re-added, repeated, and still had the same problem. Posted a question here to see if there was a firmware update. Before I gave up, I tried one last thing that I had zero expectation of working. I removed the device again from Hubitat, held down the reset button and did a factory reset, and then took the batteries out. While holding down the reset button, I put the batteries back in and did one more reset. I have no idea why or how, but this somehow fixed the issue. The sensor paired up no problem with Hubitat, configured as "Generic Zigbee motion sensor- no temp" and properly showed "ThirdReality" as the manufacturer. From there on out the sensor worked just fine. I can't explain it but if you have the same weird problem I did, try doing a couple factory resets and holding down the button while taking the batteries out and then putting them back in. LOL the mysteries of the universe.

Complete garbage. Got 1 of 2 connected pretty quickly and everything was looking good. But after about 48 hours everything went south. One became unreachable. So I reconnected it but regardless both stopped working on my zigbee network. So hours and hours of trying to disconnect and reconnect I just gave up and will now buy another brand. Such promise but these are cheaply made and my guess is they couldn't handle 50 degree F garage temps. So maybe this would work better inside a heated space. Just guessing as I could no longer handle the frustration. Update: I'm new at zigbee. I didn't realize these motion sensors are end points and not repeaters. I spend another $100 on some 3 way switches and installed them in between my controller and the sensors. Now one is green and one yellow but everything is working well now and I'm happy. It's important to realize these are not nearly as powerful as wifi. So you will need mains powered repeaters like switches in between. I've been feeling out big time and have now spent $250 just to get my garage lights to turn on and start on with motion. But it's sort of a hobby now and I've found more cool use cases like using an outdoor motion sensor to use an outdoor camera to snap a picture of my driveway and front door and text it email it and send me a telegram. My wife can get it too but she doesn't care about it as much as I do. I like to have evidence of my deliveries etc. I had to use grok extensively to figure out how to get it to work. So I'm a happy camper but you best be ready to make this a full time job for a week or two. I also now have a water sensor next to my water heater that will beep and text me an alert if it defects water. Super cool!

🏡 Seamless Integration for the Home Automation Enthusiast As a user heavily invested in Home Assistant, finding reliable and well-integrated Zigbee devices is crucial. The THIRDREALITY Zigbee Motion Sensor 4 Pack proved to be a fantastic investment. The setup process was essentially flawless: they paired quickly with my existing Zigbee coordinator and were immediately recognized by Home Assistant, allowing me to integrate them into critical automations (like motion-triggered lighting) without any complex workarounds or custom code. The sensors are fast, dependable, and, critically, they maintain a rock-solid connection to the network, which is often a pain point with other battery-powered Zigbee devices. 🔋 Smart Design & Practical Power The design of the THIRDREALITY Zigbee Motion Sensor 4 Pack shows a commitment to user convenience. AAA Battery Advantage: I greatly appreciate that these sensors use standard AAA batteries instead of proprietary or expensive coin cell batteries. This makes restocking easy and cost-effective. The manufacturer advertises up to a two-year battery life on two AAA batteries, which is excellent for a "set it and forget it" device. Coverage and Range: The sensors are capable of detecting motion up to 30 feet (9 meters) away, providing excellent coverage for large rooms and hallways. Pet-Friendly Functionality: The "Pet Friendly" feature works perfectly, minimizing false triggers from my pets while still reliably capturing human movement. This prevents those annoying late-night false alarms when lights turn on for no reason. ⭐ Final Verdict: The Go-To Motion Sensor If reliability, easy Home Assistant integration, and practical battery power are your priorities, the THIRDREALITY Zigbee Motion Sensor 4 Pack is the best Zigbee motion sensor kit available at this price point. Their consistent performance and simple setup make them a true game-changer for building out a stable smart home. I would absolutely purchase this 4-pack again as I expand my smart home network.

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).

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.

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

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.
