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

Have multiple items from thirdreality in my HA setup. they always work well, pair easily and have awesome battery life

Excellent option for Home Assistant with ZHA

I bought this sensor to replace an Eve door sensor that started flaking out on me. I really like the build quality of the sensor. To begin with, that magnet is large and powerful, which means it’s easy to set up, even if it’s a little far away from the sensor, and it will still detect when the door is opened and closed.I also really like the fact that it runs on AA batteries. Yes, that makes the device bulky, compared to other similar devices that run on coin batteries. However, AAs are a lot easier to source and more available all over the place. So I called that a win.As far as getting it set up, I was able to get it to appear in Home assistant without too much problem. However, I was not able to pair it with its own app, which I don’t really care about since I can use it in Home assistant. What bothers me a little bit, however, is the fact that I can’t seem to be able to pair it with HomeKit. Other than that, I really like this sensor, I just wish that it was easier to adopt with multiple smart home ecosystems..

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.

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.

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.

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.
