7. User Tips
- Real-time Monitoring: The device provides real-time monitoring of power consumption, current, voltage, and other parameters through the app.
- Energy Statistics: Utilize the app's electricity statistics feature to track consumption hourly, daily, monthly, and yearly for better energy management.
- Overload Protection: Configure overload thresholds in the app or directly on the meter to protect your appliances and electrical system.
- ZigBee Gateway: Remember that a ZigBee gateway (e.g., Tuya ZigBee Gateway) is essential for the smart features to work. The device does not connect directly to Wi-Fi routers.
- Bidirectional Measurement: This meter is designed for single-phase energy monitoring. For bidirectional energy measurement (imported and exported), a specialized bidirectional meter would be required.
- HA Compatibility: Please note that this device is not compatible with Home Assistant (HA) directly. It requires a Tuya ZigBee Gateway.
8. Maintenance
- Keep the device clean and free from dust. Use a soft, dry cloth for cleaning.
- Avoid exposing the device to direct sunlight or extreme humidity.
- Regularly check wiring connections for tightness and signs of wear.
- Ensure the surrounding area has adequate ventilation to prevent overheating.
9. Troubleshooting
- Device not pairing: Ensure the meter is in network distribution mode (red light flashing rapidly). Check that your ZigBee gateway is powered on and within range. Try resetting the meter by long-pressing Button 2 for 3 seconds in the auxiliary screen.
- No data in app: Verify that the meter is successfully paired with the gateway and the app. Check your internet connection and the gateway's status. Ensure the meter is correctly wired and receiving power.
- Incorrect readings: Double-check the wiring according to the diagram. Ensure the load does not exceed the maximum 80A capacity.
- LCD display not working: Check power supply to the meter. If power is present and the display is still blank, contact support.
