4.2 Electrical Installation

Professional installation is required. Ensure power is disconnected before proceeding with any wiring. The device is designed for installation in a distribution cabinet.

The TOSA1-0150XJWT2A model is a Dual Line (1P+N) device. Follow the wiring diagrams carefully.

Wiring Steps (Refer to video and diagrams):

1. Ensure the main power supply is OFF.
2. Connect the two neutral (NL) cables from the product to the power supply accordingly.
3. Thread the wires you want to measure through the SA1 current transformer. The SA1 can be placed anywhere, its connecting cable is about 80cm long, making setup quick and easy.
4. Connect the Live (L) wire to the appropriate terminal.
5. Double-check all connections for security and correctness.
6. Restore power.

4.3 Device Pairing

After successful electrical installation and power restoration, the device is ready for pairing with the app.

1. Open the Tuya or Smart Life App.
2. Ensure your phone's Wi-Fi is enabled and connected to a 2.4GHz network.
3. Press and hold the "Pairing Button" (A) on the device for 5 seconds until the blue LED indicator (D) starts flashing continuously. This indicates the device is in pairing mode.
4. In the app, tap "Add Device" or the "+" icon.
5. Select "Energy Meter" or search for the device type.
6. Follow the on-screen instructions to connect the device to your Wi-Fi network.
7. Once successfully paired, the blue LED indicator will stay solid.
8. For Zigbee versions, add the Zigbee gateway first, then add the devices.

5. Operating Instructions

5.1 Real-Time Monitoring

Once paired, you can monitor various electrical parameters in real-time via the Tuya/Smart Life App.

• Real-time Voltage: View the current voltage (V).
• Real-time Current: View the current amperage (A).
• Real-time Power (Forward): Monitor instantaneous power consumption (W).
• Power Consumption (Forward): Track total energy consumed (kWh) daily, monthly, and yearly.
• Internal Temperature: Monitor the device's internal temperature.

5.4 Smart Safety Alerts

The device provides instant warnings for various electrical anomalies:

• Over-voltage Alarm: Alerts if voltage exceeds the set threshold (e.g., 100–280V range).
• Under-voltage Alarm: Alerts if voltage drops below the set threshold.
• Over-current Alarm: Alerts if current exceeds the adjustable threshold (1–50A).
• Over-Power Alarm: Alerts if power consumption exceeds the set limit (5W–12,000W).
• Temperature Alarm: Alerts if the internal temperature exceeds a safe limit (-25°C to 100°C).
• Prepaid Monitoring: Alerts when prepaid credit is low.

5.5 Data Export

Energy consumption logs can be seamlessly exported to Excel (CSV) format for detailed analysis, monitoring, and calculating kWh usage over custom periods.

6. Maintenance

The TONGOU Smart WiFi Energy Meter is designed for low maintenance. Regular checks should include:

• Visual Inspection: Periodically inspect the device and wiring for any signs of damage, loose connections, or overheating.
• Cleaning: Keep the device free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners.
• Firmware Updates: Check the Tuya/Smart Life App for any available firmware updates to ensure optimal performance and security.

7. Troubleshooting
