THIRDREALITY Zigbee Motion Sensor 4 Pack, Zigbee Hub Required, Pet Friendly, Work with Home Assistant, SmartThings, Aeotec, Homey, Hubitat or Echo Devices with Built-in Zigbee hub

These sensors are pretty good. They don't have crazy far range, they reliably work at maybe 5 meters, with spotty performance beyond that, but for what they are advertised to be I think that's about what we expect. No reliability problems at the ranges they are designed for. Well constructed, easy to slide apart and swap batteries. Strongly recommend using the provided screws to mount this; using the sticky pad alone it may fall off your wall (though this may only have been due to my wall's paint being terrible). Zigbee as advertised, joins and operates beautifully in Home Assistant.

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!

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.

I bought these in 2022 (many of them) & they worked great with the exception that when the batteries died, I would have to reset them up all over again like they are brand new. Kind of a pain to deal with, but they worked for my hallway. However, what I’m really angry about now is that they DID NOT REQUIRE A HUB at all when I bought them!!! All of a sudden they quit working & now, in order to continue using them, I have to spend another $50-$100 for a hub. Why? They worked just fine WITHOUT A HUB! This company is just doing a money grab from their existing customers. I was still able to get it to connect to Alexa IF I put in the Alexa app that it is an “Other” motion sensor & NOT a ThirdReality detector, but the routine just won’t work anymore because they added a need for a HUB. This is BS! A company should NOT be able to render a product “unusable” unless you fork out more money to them 3 years AFTER you bought it! Do NOT buy from this company if u want their products to work years down the road. There is just no guarantee it will continue to work. They are running a scam here! I will NOT be buying a HUB to make them work. I WILL be buying a detector & Hub from a totally different company. I’m angry that I have to spend more money for this too work again, but I will NOT let this shady company get another penny from me. STAY AWAY from ThirdReality!

I’ve got these all over the house—bathroom, laundry room, top and bottom of the stairs, garage—you name it. They’ve been consistently solid everywhere I’ve put them. Pairing is quick, they show up clean in Home Assistant, and setup is about as painless as it gets. Once they’re in, you pretty much forget about them—which is exactly what you want. Battery life is excellent—they sip power. I’m not constantly chasing low battery alerts, which is a huge win when you start deploying a bunch of these. They’re not trying to be fancy—just straightforward motion detection—and they do it really well. Reliable, responsive, and easy to trust.

I purchased these sensors to replace my SONOFF SNZB-03 units, mainly because the SONOFF batteries are hard to find where I live. These sensors, on the other hand, use AAA batteries, which are much easier to source and therefore more practical. Integration with Home Assistant through ZHA was quick and seamless, showing good device compatibility. However, their motion detection sensitivity is noticeably lower compared to the SONOFF sensors. For example, one unit placed on a staircase rarely detects movement. I tried different orientations—even though the manual provides no guidance on positioning—but the issue persisted. What’s surprising is that other devices from this same brand, such as door/window sensors, buttons, smart plugs, and the night light, work flawlessly. Unfortunately, these motion sensors do not meet the same reliability standard, which is disappointing given the otherwise solid performance of the brand’s ecosystem.

As a Home Assistant enthusiast, I'm always on the lookout for reliable and affordable Zigbee devices to expand my smart home ecosystem. And let me tell you, these THIRDREALITY Zigbee Motion Sensors have become my absolute go-to for my motion automation needs. I pretty much stalk them, waiting for sales to stock up, and I have them strategically placed all over my house. What really makes these sensors shine, especially for Home Assistant users, is their rock-solid compatibility. They pair effortlessly with my Zigbee coordinator (using ZHA, of course!), and their responsiveness is fantastic. I've set up automations for lights turning on when I enter a room, fans activating, and even security alerts, and these sensors trigger them without a hitch. It's truly a "set it and forget it" experience, which is exactly what you want when building a smart home. Plus, the battery life on these things is phenomenal. I'm talking months, if not over a year, before I even need to think about replacing the AAAs. No more constantly swapping out those tiny, expensive coin cell batteries from other brands! Pros: * Flawless Home Assistant Integration: Pairs easily and works reliably with ZHA and Zigbee2MQTT. * Excellent Battery Life: Seriously, the AAA batteries last an incredibly long time, saving you hassle and money. * Reliable Motion Detection: Quick and accurate triggers for your automations. * Pet-Friendly: Designed to minimize false alerts from your furry friends, which is a huge bonus! * Good Value: Especially when you grab them on sale, they're a cost-effective way to blanket your home with motion detection. * OTA Firmware Updates: The ability to update firmware through Home Assistant is a nice touch, ensuring long-term compatibility and potential improvements. Cons: * No Temperature/Illuminance Sensor: Unlike some other motion sensors on the market, these are purely motion detectors. If you need additional data, you'll need separate sensors. * Rectangular Form Factor: While unobtrusive, some might prefer a smaller or rounder design for certain placements. Overall, if you're diving deep into Home Assistant or any other Zigbee-compatible smart home hub, you simply cannot go wrong with the THIRDREALITY Zigbee Motion Sensors. They're a fantastic, reliable, and affordable choice that will truly elevate your home automation game.

Worked great and easy to set up. I have other motion sensors that also have temperature available, but this one does not. I bought it for motion sensing and that works great. I use a Samsung Smart Things hub.

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.

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.

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.
