THIRDREALITY Zigbee Smart Garage Door Tilt Sensor, Adjustable Sensitivity Levels, 2-Year Battery Life, Zigbee Hub Required

Super simple setup and installation with Home Assistant. Works perfectly and reliably. Works well with rechargeable batteries. I wish they had a Matter/Thread version.

Update 02/07/2025 - back to 5 stars - with caveats As seen below, I had a few pain points. After buying several, I found some would stop updating. Almost as if some units that worked would stop if I added a new one. (This is in Home Assistant) There was a device firmware update. Home Assistant can not install it. The update is supposed to fix that. But you can't install it! The fix: After working with ThirdReality's support, we determined that the only way to solve this was to use their Zigbee/Matter hub. I already have a wokring different brand zigbee hub! But, they were super kind and sent me one to see if it fixes the problem. Workflow: Plug their hub into a USB power brick. Download the Android app 3r-Installer. (on to my seldom used old Android phone). Go into my WiFi router and temporarily remove the password requirement on my 2.8ghz Wifi. Connect my phone to that wifi. Use the app to find the hub. configure settings wit may want to start using it. Go into Home Assistant and remove a problematic thermometer. Bring the thermometer to where the HUB is. Reset the thermometer into paring mode. Click on the hub in the app, and then add the thermometer as a new device. (this can be a pain in the butt. Keep trying to reset the thermometer into paring mode. You will get there in the end.) Once you have it in there, you will have the ability to update the device with the latest firmware. How the update flows - the app on your android device downloads the firmware from ThirdReality and then pushes it into the hub. The hub then takes over and slowly (zigbee is a slow protocol) uploads it into the device. The update happens and the device eventually reboots and shows up again. Now, remove the device from the hub's list of devices. Reset the device into pairing mode and pair it back into Home Assistant on your old zigbee hub. Move onto the next ThirdReality device. Slow, but possible. Finally unplug the ThirdReality Hub, and put a password back into your Wifi router. (do NOT forget that part). Since then (over a week ago) all thermometers I have are placed back into their mounting locations around the house. All are working and keep updating their readings. None have failed to do so. So, the ThirdReality hub (MZ1) isn't expensive. Sure, it's an extra $30 you wish you did not have to spend. But if you are stuck trying to update your ThirdReality devices (and use a different Zigbee hub) in Home Assistant, this is a workable tool you can use and then toss in the old toolbox. I will never use it in my environment, as it is exclusively using Wifi to talk to the app, which I won't allow for my home automation. But that is just me. All of my thermometers are working and no signs of any kicking another one out of the network. --------------- Currently leaving this as a three start review. I bought a pair of these, and they worked great in Home Assistant. I decided to pick up another pair as they were on sale. They too seemed to work fine. Then I decided there are a couple of the rooms it would be great to know how the temperatures were in there and how they fluctuate. That is when the frustration came in. The new units came online, and seemed to work. Then, while they still show up in Home Assistant, they (or a different unit) stopped reporting any temperature changes. After some playing around and getting them online again, they would work for a while and then stop. It seems like when I added a new one, it would knock an old one off from reporting. Then one day I thought, I wonder if there is a firmware update for these. Yes! Great! I'll do that and see if it fixes the problem. However, Home Assistant can not successfully update them. It times out while trying. So, I went to the support portal for Third Reality, and read there is a newer update. It is specifically to help solve the problem where Home Assistant can't update the device. Ummm... So... How am I supposed to update them if Home Assistant can't do it? Right now I am in contact with Support, and they are responsive and are stepping up their game on this. But, I'll leave what we are doing so far, out of this review for now. Since I am not using their hub, the steps are little more complex. I'll update this review if it works out and everything stays online and reporting. ** for anyone who would say "move the device closer to your hub so the update works": I think 6 inches is close enough. Doesn't work. Don't worry. I am working the problem.

I've had this sensor mounted on my roll up style garage door for five months now with few issues. Others have commented about poor battery life but my sensor still reports 100% life. Mounting is very easy using double sided tape (supplied with sensor) and pairing with a SmartThings hub is also easy following the included instructions. If you don't have a SmartThings hub, you can also pair with a Zigbee enabled Amazon Alexa Echo. Most of the later Echo versions include a built in hub. My sensor is also connected to Amazon's Alexa and reports when the garage door is opened or closed which is its intended purpose. The same Alexa routine that voices that status also turns on or off garage lighting and music when the door opens or closes. One glitch (and the reason this rating is missing a star) is an occasional minute long delay in that report which also means a delay turning the lights on. I don't know if it's the sensor, the SmartThings app, Amazon or some point between all those servers and it isn't every time (normal is within a couple of seconds). Overall, I'd recommend this sensor, primarily for its simple install and setup along with Alexa compatibility.

Update: Spoke with the seller and they sent a replacement -and it worked, flawlessly. I guess I may have just had an issue with one in particular, I don't know, but the seller was incredible and very responsive. I know that in the future, I'll be looking at Third Reality again for my needs. Old review: Works great when it's within 5' of the zigbee dongle, but once outside of that range, connectivity is non-existent. I turned the alarm back on just to see if it was acknowledging the tilt, and it wasn't even doing that consistently. When it was, and it was within 5' of the dongle, things were fine. When I moved more than 5' away, I would get inconsistent chimes and open/close triggers. When I went into the garage, about 15' from the dongle, I lost everything - no chime, no open/close activity. I bought 2 and only opened and tested one, but both are going back and I'm sourcing another product. Zwave is better for longer range, even with zigbee repeaters/boosters. Too bad the old smartthings centralite sensors died, they were the best and lasted the longest.

Installation of this garage door tilt sensor was simple and took just a few minutes to complete. It paired seamlessly with my Zigbee hub and provides real-time notifications if the door is opened or closed. I appreciate the adjustable sensitivity levels, which allow me to customize the sensor to avoid false alarms while ensuring reliable detection. The two-year battery seems to last a long time, and I appreciate not having to replace it frequently. Overall, this sensor has added peace of mind and convenience to my smart home setup, and I have been impressed by its performance.

worked well for 2 months then wouldn't connect even when right next to my hub. Tried new batteries (this thing chews through batteries), removing and rejoining the network. Nothing worked. I replaced it with an Aqara like I should have from the start.

I don't use this with the third reality bridge, it pairs directly to home assistant if you have a zigbee radio which you should if you don't. Fits right into my routines to notify me when the door's been open too long. Battery life is not as good as Z-Wave device, and the range is not as good but they can use the mesh system which works fine. Overall five stars and recommended

I love almost everything about this sensor. Even the fact that I can easily 3d print some holders to make it easy to pull out to change the batteries. And that leads me to the one feature that I cannot stand - it eats batteries like a fat kid around twinkies!! I tried using rechargeable batteries at first and it was dying after only 2 months. Switched to brand new duracell batteries and now it makes it about 5 to 6 months at best. They advertise 2 year battery life, but there is absolutely no way that is true. I know it's not a defective unit because I am using 5 of these things, all purchased at different times, and they all eat batteries. It's not doing anything except monitoring for tilt, so I have no idea what is consuming this much power from two AAA batteries. I have zigbee door sensors that run off a coin size battery for 3 to 5 years, but these things act like they need to be running on a dedicated USB plug or something. This is actually pretty common with ThirdReality items I have purchased, they all consume quite a bit of battery power, but the others usually make it a year or more, but not this one. If they ever come out with a firmware update to get these to last at least a year, I would gladly update my review to 5 star.

Smartthings compatible. Works reliably for detecting when my up and over garage door is open.

détecteur très simple d'utilisation et très précis. je l'utilise avec home assistant et aucun problème de fonctionnement. reconnu par zigbee2mqtt sans aucun problème.

Funciona correctamente

Its works! Easy to install and configure in to Home Assistant. For our garage its so much better than other door sensors that are sensitive to placement and movement.

Works perfectly in the Zigbee protocol. Used here as entrance-check to turn on lights and heating, based on arrival at night.
