6.2 Automatic Shutoff and Alarms
- Ultrasonic Flow Detection: The valve uses W-type ultrasonic technology for precise flow measurement.
- Flow Rate Alarms: Set custom high or low water flow rate alarms within the app. If the flow exceeds or falls below the set values, the valve can automatically close to prevent waste or damage.
- Leak Detector Integration: Through the Tuya app, you can create automation scenes to link the Smart Water Valve with a Tuya WiFi Water Leak Detector (sold separately). If a leak is detected, the valve can automatically shut off the water supply.
