5. Setup and Installation
5.1 Pre-Installation Checklist
- Ensure you have the necessary tools (e.g., screwdriver, wire strippers).
- Confirm the electrical circuit is single-phase 220-240V, 50/60Hz, with a maximum current of 63A.
- Download the Smart Life or Tuya Smart app from your mobile device's app store.
- Ensure your Wi-Fi network is 2.4 GHz, as the device does not support 5 GHz Wi-Fi.
5.2 Physical Installation
- Turn off Power: Before starting any wiring, ensure the main power supply to the circuit is completely turned off at the circuit breaker. Verify with a voltage tester.
- Mount the Device: The compact design allows installation in various electrical boxes or distribution boards.
- Wire the Device: Refer to the wiring diagram below. Connect the live (L) and neutral (N) wires according to the markings on the device and the diagram. The arrow direction on the device indicates the forward current direction. Ensure the blue neutral wire is not incorrectly connected to the live wire, as this will cause damage.
- Restore Power: Once wiring is complete and secured, restore power to the circuit. The device's indicator light should illuminate.

5.3 App Pairing
- Open App: Launch the Smart Life or Tuya Smart app on your smartphone.
- Add Device: Follow the in-app instructions to add a new device. Typically, this involves selecting 'Electrical Engineering' or 'Energy Meter' from the device list.
- Enter Wi-Fi Details: Provide your 2.4 GHz Wi-Fi network name and password when prompted.
- Pairing Mode: The device will enter pairing mode (often indicated by a blinking light). Confirm this in the app to complete the connection.
- Device Renaming: Once connected, you can rename the device in the app for easier identification.
6. Operating Instructions
6.1 Real-time Monitoring
After successful pairing, open the Smart Life or Tuya Smart app to view real-time data from your energy meter. The app dashboard will display:
- Current (A): Instantaneous current flowing through the circuit.
- Voltage (V): Current voltage of the circuit.
- Power (W): Instantaneous power consumption.
- Energy Consumption (kWh): Total accumulated energy consumption.

6.2 Historical Data Access
The app stores historical energy data permanently. Navigate to the historical data section within the app to view consumption and production trends:
- View data by hour, day, week, or month.
- Analyze consumption patterns to identify energy-saving opportunities.
6.3 Overload and Overcurrent Alarms
The device is equipped with built-in alarms for overload and overcurrent conditions. If the current or load exceeds safe limits, the device will send an immediate notification to your smartphone via the app. Take appropriate action to prevent damage to appliances or the electrical system.
6.4 Solar Power Generation Monitoring
For systems generating electricity (e.g., solar panels, wind turbines), the meter can measure reverse current. This allows you to accurately track the amount of electricity your system generates and feeds back into the grid or consumes locally. Ensure the device is installed correctly to measure both forward and reverse current flow.
