5. Installation
Important: Installation should only be performed by a qualified electrician. Ensure power is disconnected before beginning any electrical work.
5.1. Physical Installation and Wiring
The energy meter and CT clamp are designed for installation within an AC distribution box or similar electrical enclosure. The main unit connects to the live (Lin) and neutral (Nin) wires of the circuit you wish to monitor, and the CT clamp is clipped around the live wire of that circuit.
Image 3: The CT clamp is shown clipped around a red cable inside an electrical panel. The cable being measured needs to carry a load above 10W for accurate readings.
Wiring Diagrams:
Detailed wiring diagrams are crucial for correct and safe installation. Please refer to the official PDF user manual for visual guidance. A general description of common wiring scenarios is provided below:
- To measure energy consumption and energy generation: The CT clamp is typically placed around the main live wire (L) coming from the Grid/AC Distribution Box, before any connections to an Inverter/Solar Panel and the main Load. The module's Lin terminal connects to the Live (L) wire, Nin to the Neutral (N) wire, and the CT (Red, Black) wires connect to the CT clamp.
- To measure 'from Grid' or 'to Grid': The CT clamp is placed around the main live wire (L) coming from the Grid/AC Distribution Box, after the Inverter/Solar Panel connection and before the Load. The module's Lin terminal connects to the Live (L) wire, Nin to the Neutral (N) wire, and the CT (Red, Black) wires connect to the CT clamp.
Note: When installing, please ensure that the circuit measured by the CT clamp is in the same phase as the circuit powered by the module itself.

5.2. Network Access Operation (App Pairing)
Once the device is physically installed and powered on, follow these steps to connect it to your Wi-Fi network and the Smart Life/Tuya Smart app:
- Ensure your AVATTO Energy Meter is energized and your mobile phone is connected to your 2.4GHz Wi-Fi network.
- Long press the reset button on the device for more than 5 seconds until the indicator light begins to flash rapidly (approximately 2 times per second). This indicates the device is in pairing mode.
- Open the "Smart Life" or "Tuya Smart" application on your smartphone.
- Tap the "+" icon in the top right corner of the app to add a new device.
- Select the appropriate Device Type (e.g., 'Electricity Meter' or 'Power Monitor').
- Confirm within the app that the indicator light on your device is rapidly blinking. The app will automatically attempt to fetch the password of the Wi-Fi network your mobile phone is connected to.
- Tap "Confirm" or "Next" in the app to initiate the connection process.
- Once the app displays "Successfully added 1 device", the connection is complete, and your energy meter will be listed in your smart product list within the app.
6. Operation
After successful installation and pairing, you can use the Smart Life or Tuya Smart app to monitor and manage your energy meter.
6.1. Power Statistics
The app provides real-time power statistics, allowing you to check voltage, current, and power at any time.

6.2. Measurement Process
The CT clamp continuously measures the current flowing through the cable it's clipped onto. Ensure the cable carries a load above 10W for accurate readings.
6.3. Power Settings
Within the app, you can set upper and lower limits for power and implement automatic measurement functions. This allows for customized monitoring and alerts.

7. Maintenance
- Cleaning: Use a soft, dry cloth to clean the device. Do not use harsh chemicals or abrasive cleaners.
- Firmware Updates: Periodically check the Smart Life/Tuya Smart app for available firmware updates to ensure optimal performance and security.
- Environmental Conditions: Ensure the device remains within its specified ambient temperature range (-10°C to 50°C) and away from moisture.
- Inspection: Regularly inspect the wiring and connections for any signs of wear or damage. If any issues are found, consult a qualified electrician.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not connecting to Wi-Fi | Incorrect Wi-Fi password; 5GHz Wi-Fi network; device too far from router; interference. | Ensure correct 2.4GHz Wi-Fi password. Move device closer to router. Reduce interference from other devices. Re-enter pairing mode and try again. |
| No power readings in app | CT clamp not correctly installed; cable load too low; wiring issue. | Verify CT clamp is securely clipped around the live wire. Ensure the monitored load is above 10W. Check all wiring connections (Lin, Nin, CT) are secure. |
| Inaccurate readings | CT clamp installed on wrong wire; phase mismatch. | Ensure CT clamp is on the live wire only. Verify the circuit measured by CT is in the same phase as the module's power supply. Consult a qualified electrician. |
| App shows device offline | Wi-Fi signal lost; device power lost. | Check Wi-Fi router and internet connection. Ensure the energy meter has continuous power. If Wi-Fi was changed, re-pair the device. |
9. User Tips
- Optimal Wi-Fi Placement: For best performance, ensure your Wi-Fi router is centrally located and within reasonable range of the energy meter, especially if installed in an electrical panel which can sometimes attenuate signals.
- Regular Monitoring: Make it a habit to check your energy consumption regularly through the app. This can help identify unusual power usage patterns and potential energy savings.
- App Notifications: Utilize the app's notification features to set alerts for high power consumption or other anomalies, helping you stay informed about your electricity usage.
- Data Export: If available in the app, export your energy data periodically for detailed analysis or record-keeping.
