5. Operation

5.1 Real-time Water Monitoring and Control

Once connected, the app provides a dashboard to monitor and control your water valve.

• Flow Rate Display: View the current water flow rate in real-time (e.g., gallons per hour).
• Total Water Usage: Track the total water consumed over time.
• Valve Control: Manually open or close the water valve directly from the app.

5.2 Smart Water Meter Functions

The app allows you to access historical water consumption data and manage settings related to water usage.

• Historical Data: Navigate to the "History" section in the app to view daily, monthly, and yearly water usage statistics.
• Reset Usage: In the "Settings" menu, you can reset the water usage data.
• Unit Change: Adjust the flow rate unit (e.g., gal/h, m³/h, L/h) in the settings.

5.3 Automated Scenes and Alarms

Leverage the automation features to enhance water safety and convenience.

• Flow Rate Alarms: Set high or low flow rate thresholds in the "Flow Rate Alarm" settings. If the water flow exceeds or falls below these values, the valve can be configured to automatically close, preventing water waste or damage from leaks.
• Integration with Leak Detectors: Create custom scenes in the Tuya app to link the water valve with a Tuya WiFi Water Leak Detector (sold separately). For example, if a leak is detected, the scene can trigger the smart water valve to automatically shut off the water supply.
