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

UPDATED BELOWI 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 8 of these when they were $10 each. Needed a way to combine all my zigbee and wifi products (appx 60 devices). Initially hooked them up to Alexa, which worked fine, but I needed more customization. I wanted to try all the options out there. I bought a conbee II stick, a sonoff zigbee stick, a cheap, used chromebox (flashed HA OS onto it), and a Hubitat. Long story short, I like the combo of the Chromebox and Hubitat without the zigbee sticks.After a lot of work, all my Merkury (Tuya wifi lights and LED strips) and zigbee lights and sensors work harmoniously. They are mostly controlled by these Third Reality motion sensors. It's awesome how I can walk through my home and have the lights follow me to whichever room I go. Then, within a few minutes, the lights will dim, and eventually turn off when I'm not in the room. I no longer have to worry about the kids leavings all the lights on in the house, at full blast, all day. They know they can just walk into a room and things will turn on, then turn off on their own after a couple minutes of no motion.I personally don't think the sensors are slow, but they're not completely instant. However, very satisfactory IMO. It mostly depends on the placement of the sensor. I tested the placement of each sensor for a few weeks before deciding on final placement. Sometimes they "see" too far off into the distance, which can be 10+ feet. However, in one room, I have to enter the darkness for ~1 second before the lights turn on. It's not the sensor's fault; it's due to placement. We just know we can't dash into the room - we need to watch that first step for one small second, which I'm fine with. I can easily place another sensor right outside the room, but then it would be turning on excessively.I spent a month tinkering, for hours a day, to ensure perfection. My lights are set to dim after 2 minutes of no motion, then turn off after 5 minutes of no motion. When we're sitting at the dining room table (within 5 feet of the sensor), it will (generally) not recognize smaller/regular eating and drinking motions, thus making the lights dim. However, the timer will reset if I get out of my chair. So, these sensors are not good enough to be a true occupancy sensor, which can detect super small movements. But with my kids the sensor is reset enough, with all the moving around and getting up, to keep the lights on. However, it's not going to sense you if you're just sitting there quietly eating.Anyway, I really like them and I want some more to make the sensing more precise. I want to combine automations so they they react only when multiple sensors are triggered. However, I don't want to spend $20 on each one, or even $17. They're worth it if you only need a few. But for the amount I want, I need the $10 deal!I want to thank Youtube and all the awesome home automation channels that showed me how to do all of this. It was definitely a big time commitment. Lots of frustration, but lots of fun and very satisfying to see my final product.

Works with Samsung The Frame TV!This little device (much smaller than expected, luckily) is working with my Samsung The Frame TV to turn on art mode with motion. When I got a frame for the TV, the built in motion sensor no longer worked and I wanted to find a work around. This is an inexpensive way to have that feature back.First, make sure to turn off the motion sensor in the Art Mode on the TV. It’s called the “sleep timer.”Next, go to your Smart things App and click on Devices and add your The Frame as a “hub.”Once you’ve done that, while in Devices still, add this Third Reality (Zigbee) sensor.Once you’ve done connect the sensor, go to Routines in the app. Click on the large + sign in the upper right hand corner to add a routine.IF (choose device status), choose Third Reality Motion Sensor and then choose Motion Detected. Then Done.When prompted choose the THEN, Control Devices, choose your tv and then choose Art Mode On.You will be able to choose a time before it happens, I chose 2 seconds.Then I made a second routine for it to turn off the tv when no motion is detected for 30 min.
