Featuring a compact design, 2-year battery life, and effortless Alexa integration, it empowers you to automate alerts and routines for a smarter, safer home. The upgraded app provides real-time battery and activity tracking, ensuring you never miss a beat in 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: 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. Review: 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. ## Features - ZIGBEE STANDARD COMPATIBLE DOOR SENSOR: Works with most of Zigbee hubs or Echo devices with build-in Zigbee hub.

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. ### ⭐⭐⭐⭐⭐ Review *by A***W on 10 December 2025* 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! ## Frequently Bought Together - THIRDREALITY Zigbee Contact Sensor 2 Pack,Door and Window Monitor, Home Automation,Works with Home Assistant,SmartThings,Aeotec,Homey,Hubitat or Echo Devices with Build-in Zigbee Hub,hub Required - THIRDREALITY ZigBee Smart Plug 4 Pack with Real-time Energy Monitoring,15A Outlet, Zigbee Repeater,ETL Certified,ZigBee Hub Required,Work with Home Assistant,Compatible Echo Devices and SmartThings - THIRDREALITY Zigbee Motion Sensor 2 Pack, Zigbee Hub Required, Pet Friendly, Work with Home Assistant,SmartThings, Aeotec,Homey, Hubitat or Echo Devices with Built-in Zigbee hub --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/459844656-zigbee-contact-sensor-2-pack-door-and-window-sensor-home](https://www.desertcart.be/products/459844656-zigbee-contact-sensor-2-pack-door-and-window-sensor-home) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-05-03*
