Reliable and Long-Lasting, Works Perfectly with SmartThings
This product is very reliable with a long battery life, which sets it apart from the cheaper Chinese models I have tried. It integrates smoothly with SmartThings, providing a hassle-free experience. Overall, it works consistently well without interruptions, making it a great choice for smart home setups.

Simple and easy to use
I set these up with home assistant and SLZB-06M with ZHA. Red light blinks on when closing or opening. The sensitivity is great so I can know if my door is cracked open even a tiny bit. Reliability has been great so far. I appreciate that this uses AAA batteries, which are cheaper and easier to find than button cells.

Reliable and Easy to Use!
I added a couple of these THIRDREALITY Zigbee contact sensors to my smart home setup and they work flawlessly. Pairing with Home Assistant was quick and easy, and they respond instantly when a door is opened. The battery life has been great so far, and the build quality feels solid. Perfect for peace of mind and home automation. Highly recommend!

Good sensor, short battery life
Works well as a door sensor. Knocked down a star because of short battery life – I had to replace the batteries (2xAAA) around every 3 weeks. This is a short time compared to other door sensors I have, which typically have a battery life of 6 months or more on a button cell.

Good for the value
I love how the battery are AA batteries. Connect just fine to home assistant very responsive to home assistant.

The best door sensor!
I want devices that don’t use coin batteries so this using AAA is perfect. Works perfectly with Aeotec Z-Stick 10 Pro hub.

Not great.
I have various sensors that are similar from other manufacturers. All have been great, especially the original Smartthings devices. Tried this one. Like the AAA batteries and life. But it is far from working reliably with a 16mm or smaller gap between the switch and magnet! In general all my Thirdreality Zigbee devices are flakey.

Physically fragile technically great.
Functionally, these sensors are great. Just be aware they’re a bit fragile and really not designed to be removed once installed. The magnet portion, in particular, can crack if you take it off after mounting—I had to repaint my doors and removed three of them, and all three ended up with small cracks. Nothing a little super glue couldn’t fix, but still worth noting.After reinstalling, the gap between the magnets and the sensor ended up slightly too large, so the sensors occasionally reported the door as open even when it was fully shut. I resolved this by 3D-printing small risers shaped like the original magnet housing, and that fixed the issue.Despite these quirks, I’m still giving them five stars because I’ve had zero technical issues. They work reliably and do exactly what they should. Just know going in that they aren’t really meant to be reused. You’ve been warned.

Einrichtung mit homeassistant hat problemlos funktioniert. Verbindung zu Router ohne Probleme. Somit Aussage einer 2 Sterne Rezension dass kein mesh möglich ist schlicht falsch. Sendet Zustand permanent nicht nur wie Sensoren anderer hersteller beim Öffnen oder schließen. AAA Batterie kann leicht gewechselt werden. Einziger Nachteil ist dass er etwas größer ist wegen der Batterien aber das ist aufgrund dass Daten alle paar Minuten gesendet werden verständlich. Hab noch nichts besseres gefunden und schon viele Sensoren ausprobiert.
