Style: Door Sensor 4 Pack
I bought THIRDREALITY Zigbee Contact Sensor 4 Pack for for $41.99 on Noveber 21, 2024. This contact sensor is definitely one of the sensors I have, and it works well every single time. I love that it uses AAA batteries unlike other sensors I have, and I had no issues connecting it to Hubitat. One item to note is that these contact sensors are rather big. My other sensors are significantly smaller, but they also do not use AAA batteries. Given that my sensors are not easily visible where I placed them, their size is not an issue for me. But be aware that these are big / slightly bulky. I am very happy with this and would definitely buy them again.

This sensor is very easy to set up and use with Home Assistant, with quick reaction to open/close. If you need to reset it, open the larger piece using the button on the side, then press and hold the button next to the battery compartment for a few seconds, the LED will flash red and then pulse blue to indicate pairing mode. The only issue I had was with the supplied double-sided tape, which eventually let the large sensor piece fall off. My solution was to use adhesive Velcro - which also makes it easier to remove for battery replacement etc.

These THIRDREALITY Zigbee Contact Sensors work great so far. They trigger quickly, and setup with ZHA in Home Assistant was straightforward. The strong magnets were a nice touch—made it easy to install on doors and windows that have a bit of a wider gap. There’s a custom ZHA quirk available to tweak trigger times, which is useful, but honestly, it’d be better if this feature was built-in from the start. Overall, these sensors are a solid choice if you’re looking for something fast and easy to set up, with a few extra tweaks available if you want them.

We use these with Home Assistant and they work great. I've had my first ones for a year now and I haven't had to change the batteries. I also use one out at our mailbox - about 70 yards away - and the signal is really good. Great product with lots of uses. I do wish the plastic box weren't so bulky. Opening them up to insert the battery you can see there is lots of extra space inside. Perhaps an updated and smaller design is in their future. If so, we'll buy them for every single window!

Works just like the others but runs longer on batteries and uses regular batteries. Doesnt have temp or tamper but works fine with hubitat. look for community driver for extra options

I have recently been migrating away from Tuya cloud devices to more Zigbee alternatives so I can have more offline-ready control of my smart devices. One unexpected benefit is simply latency. I have a closet that when opened, brightens the light in a hallway in front of it, and this is now instantaneous with these Zigbee sensors. Before it would take 4-5 seconds with a Tuya equivalent. Battery life has yet to be determined, but so far I am impressed.

Doesn’t work. Always incorrectly reports the door as “open.” AFAIK there is no way to troubleshoot it, so it will be returned. Completely non functional.

Updated review 11/14/22 and reinstated 5 star rating: Apparently, during the last week or so of October 2022, there was a software issue of some sort between this device (contact & motion sensors) and my Echo Show. I think it was a zigbee issue. A lot of users of zigbee-enabled devices complained about it on reddit. I don't know the exact problem because it's all hush-hush, keep the customer uninformed. Apparently, it was corrected by Amazon after approximately one week. My Third Reality zigbee contact and motion sensors all work beautifully at the moment. Until the next glitch, of course. I reinstated my original 5 star rating because I really like how these devices work for me (except for the glitches, of course). ----------------- Updated review 10/31/22 and 1 star rating: It worked great, until it didn’t. It disconnected from Alexa and won’t reconnect. The sensor itself works. The red light lights up when the door is open, but what good is a sensor when Alexa can’t tell you the door is open? ——————— Original review 10/13/22 and original 5 star rating: This device works with my Echo Show with zigbee. I asked Alexa to "find my device" and she did. I didn't need any other hub, app, or skill, and I like that it's not wifi. I purchased a couple to use on interior doors at night so I know if a door opens or not. I set up an Alexa routine. In my house, Alexa announces the door is open within 3 seconds of opening the door. There is no down or recovery time. It'll work again within seconds. I'm very happy with it and its easy integration via zigbee with the Alexa app.
