Great contact sensor

Ordered one of these to replace my older, smaller version. This added easily to my network and has been working great. Seems to be very reliable

I was happy with it, then it went haywire, then it returned to working properly

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.

Easy to configure

This product is good. It’s easy to configure. I am using this with samsung smart things and it was a breeze to connect with smart things and using it with alexa. Only issue is, there is few seconds of time lag when the door opens.

Seems to work very well so far.. with Homeassistant...

Just got these, only had for a short time, so far, very good battery life, they ARE a little bigger-bodied than most, therefore more noticeable, but seem to stay secure when fastened by included sticky tape. Responsive to my Homeassistant system, zigbee is pretty quick for them.

Excellent!

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.

Terrible products

Don't waste your money, or your time, on Third Reality products. No range, disconnect frequently, and chews up battery life. They're all just useless products. I bought several different sensors. Motion and contact. Difficult to pair, and then disconnect often. Seriously, just find a different product manufacturer.

Works great with Home Assistant and ZHA

Using with Home Assistant and ZHA; paired quickly and has performed great since installing. Replaced an older Iris door/window sensor that went offline constantly. Nice to open my door and have my lights turn on again! I little on the big side so it might not work on some windows but I can't imagine it not working on most doors. Would buy again.
