THIRDREALITY Zigbee Contact Sensor 2 Pack, Door and Window Sensor for Home Security and Smart Home Automation, Works with Build-in Zigbee Hub,hub Required.

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.

Honestly, love these little sensors. I love that you can leave a small gap and it still detects the sensor magnet. Really good for things that need a BIT of space between the sensor and the magnet! No complaints with these guys! Easy to pair and and quick to report any changes.

These are GREAT sensors so far. Had them installed for about two weeks now and zero issues. The install and integration to my Smarthings environment was easy. In fact, these were the simplest devices to find and add to the n/w I’ve ever experienced - normally I have to stand on my head, face north and contact some spiritual being to add sensors 😜 One other functional item I’ll note is the distance between the two parts can be fairly large, like over an inch, and still work. There’s an embedded LED in the receiver that lights when the transmitter (magnet) is sensed, which is super helpful when installing and checking functionality. Anyhow, I’m planning to buy more!

Work perfectly with my Zigbee setup. They use standard batteries, which is super convenient, and the battery life has been great so far. Solid, reliable connection too.

Funciona correctamente. Su señal es algo débil y puede llegar a no ser detectado por el coordinador si está separado de éste por 10 mts en línea recta y separados por una pared gruesa. En este caso, la solución es instalar a un dispositivo Zigbee emchufable que oficie de repetidor.
