2. Identify the direction of water flow in your pipe. The water meter has an arrow indicating the correct flow direction.
3. Cut the pipe at the desired installation point, ensuring enough space for the meter and connectors.
4. Apply pipe sealant tape to the threads of the brass connectors.
5. Attach the brass connectors to the inlet and outlet of the water meter, ensuring the rubber gaskets are properly seated to prevent leaks.
6. Connect the assembled meter to your water pipes, tightening securely with a wrench. Do not overtighten.
7. Slowly turn the main water supply back on and check for any leaks.

4.3. Zigbee Network Connection:

To enable smart features, the water meter must be added to your Tuya Zigbee network via a Tuya Zigbee Hub.

• Software Updates: Keep your Tuya app and Zigbee Hub firmware updated to ensure compatibility and access to the latest features and security patches.

7. Troubleshooting

If you encounter issues with your smart water meter, refer to the following common problems and solutions:

• No Data Upload to App:
  • Ensure the water meter is within range of your Tuya Zigbee Hub.
  • Check if the Zigbee Hub is online and connected to your home network.
  • Verify the meter's battery level. Low battery can prevent data transmission.
  • Check the data upload frequency setting in the Tuya app.
• Valve Not Responding to Remote Control:
  • Confirm the meter is connected to the Zigbee network and online in the app.
  • Check for any alarm conditions that might prevent valve operation (e.g., pipe burst alarm).
  • Ensure sufficient battery power for valve operation.
• Alarm Notifications (e.g., Leakage, Pipe Burst):
  • Immediately investigate the source of the alarm. Turn off the main water supply if a leak or burst is confirmed.
  • Address the underlying issue (e.g., repair pipe, tighten connection).
  • Once the issue is resolved, the alarm should clear. Some alarms may require manual reset via the app.
• Inaccurate Readings:
  • Ensure the meter is installed correctly with the arrow pointing in the direction of water flow.
  • Check for air bubbles in the pipe system, which can affect ultrasonic readings.
  • Verify there are no obstructions immediately before or after the meter.
• Meter Display is Blank:
  • Check the battery. Replace if necessary.
  • If battery replacement does not resolve the issue, contact customer support.
