Product Overview
The backbone of a reliable Home Security System. Unlike WiFi sensors that can go offline or delay alerts, this ZigBee 3.0 Door Sensor connects via a gateway to ensure 100% uptime and instant response. It supports Local Linkage, meaning if an intruder opens the door, the linked siren will blast immediately even if the internet is cut. With ultra-low power consumption, it minimizes maintenance costs for large-scale installations in hotels and offices.
Frequently Asked Questions
Why use ZigBee instead of WiFi for security?
ZigBee is faster, uses less battery, and doesn't clog the router. Most importantly, security automations (like "Open Door → Siren") run locally on the gateway, ensuring they work even if the internet fails.
How long does the battery last?
Thanks to the low-power ZigBee protocol, the AAA batteries can last up to 2 years, significantly longer than WiFi versions.
Can I monitor multiple doors on one app?
Yes, you can add hundreds of sensors to a single Tuya ZigBee Gateway and view the status of all windows and doors in the Smart Life App.
Does it have a "Door Left Open" alert?
Yes, you can configure a smart scene to send a notification if the door remains open for more than a set time (e.g., 5 minutes).
Is it compatible with Home Assistant?
Yes, it follows the standard ZigBee 3.0 protocol, making it compatible with Tuya hubs as well as open platforms like Home Assistant (ZHA/Zigbee2MQTT).
