How It Works

The sensor consists of two parts: a main unit and a small magnet. When the two pieces separate (i.e., a door or window opens), the sensor instantly sends a signal through your Zigbee hub to the Tuya / Smart Life app. You can configure automations — such as turning on a light or sounding an alert — every time an entry point is opened or closed, giving you smarter, hands-free awareness of your home.

Frequently Asked Questions

Q: Does the Tuya Zigbee 3.0 Door & Window Sensor require a hub?

Q: Which doors, windows, or gates is this sensor compatible with?
