## Overview

The THIRDREALITY Zigbee Contact Sensor 2 Pack offers reliable, fast Zigbee connectivity compatible with major hubs like Echo and SmartThings. Designed for easy installation and long-lasting performance with up to 2 years of battery life, it enables real-time door/window monitoring and customizable Alexa routines. Its compact design ensures stable contact even on uneven surfaces, while the Third Reality app provides battery status and event history, making it a must-have for proactive, modern home security.

## Description

Door and window sensor can directly work with compatible ECHO. And its compact design can fit in most doors and windows. Most of the doors or windows have a height difference from the doors' or windows' frame. With the special design the height difference can be reduced to make sure the two parts of the door sensor have a stable contact. Simply peel off the protective layer of double-sided tape and stick the two parts of the door sensor to the door and the door frame. You can monitor every door and windows in your home and create routines to send messages to your smartphone when the door or window is open. You also can create routines that are triggered by the on/off status of the door sensor.

Review: Great Sensors - Excellent. I have a mix of Sonoff and these, and the Sonoff ones often disconnect and are not easy to use. These always stay connected, have great battery life, and are easy to open and replace batteries. They are larger than some, but I haven't noticed and it's worth it.
Review: They work well with SmartThings - As time goes on there are fewer and fewer things that impress me and actually improve how I interact with my smart home. Well today is a new day and color me impressed. These contact sensors work phenomenally. They work really fast with my SmartThings hub they paired automatically with the correct driver all I did was scan for a device. I was a bit worried as the correct device did not show up by selecting third reality from the add device list. I really like that it takes 2 AAA batteries as they are easily accessible. I have never thought that a contact sensor would be useful and preferred motion and presence sensors. However I installed these on the utility room door and a door to a walk-in closet. Both of which are not really big enough to close yourself in. These work perfectly open=on & closed=off. It's all ZigBee so virtually no lag by the time the door is open enough to walk through the lights are on. I'm a fan & I am thinking of ways to implement more.

### ⭐⭐⭐⭐⭐ They work well with SmartThings
*by M***R on 29 July 2025*

As time goes on there are fewer and fewer things that impress me and actually improve how I interact with my smart home. Well today is a new day and color me impressed. These contact sensors work phenomenally. They work really fast with my SmartThings hub they paired automatically with the correct driver all I did was scan for a device.

### ⭐⭐⭐⭐⭐ Works really well, simple to set up, very responsive
*by J***E on 6 May 2026*

These are really good. They work very reliably and hooked into the SmartThings ecosystem and my hub without any issues. It's Zigbee based so most Zigbee systems should be compatible but check first. Your milage may vary since the ecosystem and hub interoperability of smart home tech is a mess. The mounting and installation is easy and intuitive with the ridge to ridge contact points between the door and the frame needing to line up. Manual says the gap distance can be up to 16mm but I've found it supports a wider gap close to 25mm. Which is good. The only knock I have against these is the adhesive pads aren't great and if you try to position the two sensor parts too close together the air rush of the door swing can loosen them. Getting your own better adhesive pad and widening the gap slightly worked way better. Box does have screws included if you wanted to go that route to secure these to the frame and door but I didn't personally want to go that.
