Image 4.3: The app interface displaying current flow rate (e.g., 7.25 gal/h) and total water consumed (e.g., 10.6 gal).
4.3 Water Consumption Statistics
The app provides detailed statistics on your water consumption, including daily, monthly, and historical data. This allows for efficient water management and waste reduction.

Immaġni 4.4: Eż.amples of water consumption graphs within the app, showing usage patterns over different time periods.
4.4 Automated Scenes with Water Leak Detectors
Through the Tuya app, you can set up automated scenes. For example, if a Tuya WiFi water leak detector (sold separately) detects a leak, the smart water valve can be configured to automatically close, preventing significant water damage.

5. Manutenzjoni
5.1 Ġestjoni tal-batterija
The valve includes a built-in 2600 mAh NiMH rechargeable battery. This battery provides power for 3-6 months on a full charge, allowing the valve to operate even during power outages. Nota: When operating solely on battery power, the app cannot be used to control or monitor the valve.
5.2 Kura Ġenerali
Keep the device clean and free from excessive dust or moisture. Do not use harsh chemicals for cleaning. Ensure the power connection is secure when operating on AC power.
6 Issolvi l-problemi
- Apparat mhux qed jikkonnettja mal-WiFi: Ensure your router is broadcasting a 2.4 GHz network. The device does not support 5 GHz WiFi. Verify your WiFi password and network stability.
- Il-kontroll tal-app mhux qed jaħdem: Check if the device is connected to AC power. In battery-only mode, app control and monitoring are disabled. Ensure your smartphone has an active internet connection.
- Inaccurate flow rate readings: Ensure the valve is installed correctly according to the flow direction. If issues persist after initial setup, a firmware update might be required (check the app for updates). Note that some users have reported minor discrepancies (2-3%) compared to calibrated meters.
- Slow app updates for flow/consumption: The app may update flow rate and consumption data every 60 seconds. This is normal operation and not an indication of a fault.
- Issues with third-party integrations (e.g., Home Assistant): This product is primarily designed for use with the Tuya Smart app. Integration with other smart home platforms may have limitations or require specific configurations not officially supported.
