Frequently Asked Questions
Q: Does the Zigbee Door Sensor work without a hub or gateway?
A: No — this Zigbee contact sensor requires a Zigbee Gateway Hub to function. It cannot connect directly to your home Wi-Fi router. Compatible hubs include Tuya-based Zigbee gateways and the eWeLink ZigBee Gateway Hub. Once paired through a gateway, you can control the sensor via the Smart Life or Tuya app.

Q: How do I install this window contact sensor?
A: Installation is straightforward and tool-free. Attach the two sensor pieces on either side of your door or window frame using the included double-sided adhesive tape. Optionally, you can use screws for a more permanent mount. Then open the Smart Life or Tuya app, add the device through your Zigbee gateway, and you're ready to go — the whole process takes just a few minutes.
Q: What batteries does the door sensor use, and how long do they last?
A: The sensor runs on 2 × AAA 1.5V batteries (not included). Thanks to its ultra-low quiescent current (≤10 µA), batteries typically last a long time under normal use. The sensor will automatically send a low-battery notification to your smartphone so you always know when replacements are needed.
