Review: GREAT NO-FRILLS SENSOR- 35 second recovery time! - 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.
Review: Works great with Samsung hub. - 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.

### ⭐⭐⭐⭐⭐ The Unsung Heroes of Home Assistant: THIRDREALITY Zigbee Motion Sensors!
*by M***L on July 20, 2025*

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.
