3. Setup and Installation

Proper installation is crucial for accurate readings and reliable operation. Professional installation is recommended.

Prerequisites:

• A Tuya Zigbee Hub is required for the water meter to function with the Tuya Smart App.
• For Home Assistant integration, an additional add-on is necessary. Contact customer service for details.
• Ensure the installation location is accessible and suitable for plumbing work.

Installation Guidelines:

1. Flow Direction: Ensure the arrow on the meter points in the same direction as the water flow.
2. Space Requirement: Leave sufficient space around the meter for future maintenance.
3. Accurate Readings: For precise measurements, ensure straight sections of pipe before and after the meter: at least 10 times the pipe diameter before the meter, and at least 5 times the pipe diameter after the meter.

Correct Installations:

• M-1 (Horizontal, low in pipe): This is correct. Mounted low with back pressure at the outlet. Prevents air bubbles and ensures accuracy.
• M-2 (Vertical, flow upward): Also correct. Similar to M-1, this position prevents air bubbles and maintains accuracy.

Incorrect Installations:

• M-3 (Horizontal, high in pipe): This is incorrect. Mounting high can trap air bubbles, which will affect measurement accuracy.
• M-4 (Vertical, flow downward): This is incorrect. Downward flow in a vertical installation is not allowed.

Pairing with Tuya Zigbee Hub:

After physical installation, the device needs to be paired with your Tuya Zigbee Hub. The pairing process typically involves:

1. Ensure your Tuya Zigbee Hub is powered on and connected to your network.
2. Open the Tuya Smart App and navigate to your Zigbee Hub.
3. Initiate the device search/pairing mode within the app.
4. On the water meter, locate the single push button. Cycle through the display screens until you find the pairing mode screen. A long press of the button on this specific screen will activate pairing mode. The exact screen may require several attempts to locate.
5. Once in pairing mode, the meter should be discovered by the Tuya App. Follow the on-screen prompts to complete the pairing.

4. Operating Instructions

The water meter can be operated via its LCD display or through the Tuya Smart App.

LCD Display Operation:

The device features a single push button to cycle through various display screens. These screens show parameters such as total water consumption, current flow rate, and pipe temperature. Some cryptic parameters may be adjustable, but their functions are not detailed in standard documentation. The primary use of the button is for cycling through information and initiating pairing mode.

Tuya Smart App Operation:

Once paired, the Tuya Smart App provides comprehensive control and monitoring capabilities.

• Remote Monitoring: View total water consumption, current flow rate, and pipe temperature from anywhere.
• Valve Control: Remotely open or close the built-in shutoff valve.
• Data History: Access detailed consumption history (hourly data for 7 days, daily for a year) to analyze usage patterns.
• Custom Data Upload Intervals: Adjust how frequently data is uploaded to the app (1-24 hours).
• Smart Threshold Alarms: Configure alerts for abnormal water flow or other parameters.

5. Maintenance

The Blindsmart Zigbee Smart Water Meter 214C is designed for minimal maintenance.

• Battery: The device is powered by a large 9000mAh built-in lithium battery. This battery is not user-replaceable as the entire device is sealed. The battery is designed for long-term operation. Frequent operation of the shutoff valve may reduce battery life.
• Cleaning: Periodically wipe the exterior of the device with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Inspection: Regularly inspect the meter and pipe connections for any signs of leaks or damage.

6. Troubleshooting

Common Issues and Solutions:

• Device Not Pairing:
  • Ensure your Tuya Zigbee Hub is online and in pairing mode.
  • Confirm the water meter is in pairing mode by cycling through its display screens and long-pressing the button on the correct screen. This step can be challenging; persistence may be required.
  • Verify the meter is within range of the Zigbee Hub.
• Inaccurate Readings:
  • Check that the meter is installed according to the flow direction arrow.
  • Ensure the recommended straight pipe lengths before and after the meter are met.
  • Verify the installation orientation is correct (horizontal low in pipe or vertical flow upward) to avoid air bubbles.
• No Data in App:
  • Confirm the device is successfully paired and connected to the Zigbee Hub.
  • Check your internet connection for the Tuya Zigbee Hub.
  • Verify data upload intervals in the app settings.
• Leak Detection Alerts Not Functioning:
