• Do NOT attempt to disassemble, repair, or modify the device.

4. Installation Guide

4.1 Wiring Instructions

Connect the wires according to the provided wiring diagrams. Ensure all connections are secure before restoring power.

Important Note for CT Clamp Installation: The current transformer (CT) clamp must be installed correctly. The arrow on the clamp should face the direction of the electricity current flow (P1 to P2, or towards the load). Clamp it on the live wire more accurately; do not clamp two wires with a single CT clamp.

4.2 App Installation and Device Pairing

1. Download the App: Scan the QR code below or search for "Tuya Smart" in your device's App Store (iOS) or Google Play Store (Android) to download the application.

   

2. Register/Log In: Open the Tuya Smart App. Log in to your existing account or register a new one using your mobile number or email address. Follow the on-screen prompts to verify and set up your account.
3. Prepare Device for Pairing: After completing the wiring of the energy meter, open the terminal box cover. Press and hold the "Reset" key for approximately 10 seconds until the LED indicator light on the module is flashing quickly. This indicates the device is in pairing mode.
4. Add Device in App:
   • Ensure your mobile device's Bluetooth is enabled.
   • Open the Tuya Smart App, click the "+" icon (usually in the top right corner) to add a device.
   • The app should automatically detect nearby devices. Select "Smart meters" or the detected energy meter from the list.
   • Enter your 2.4GHz Wi-Fi network name and password when prompted. (Note: 5GHz Wi-Fi networks are not supported).
   • The app will then proceed to add the device. This process may take 10-120 seconds depending on your network conditions.
   • Once successfully added, click "Done".

5. Operating Instructions

5.1 Real-time Monitoring via Tuya App

Once connected, you can monitor your energy meter from anywhere using the Tuya Smart App. The app provides real-time data for each channel:

• Voltage (V)
• Current (A)
• Total Power (W)
• Power Factor
• Frequency (Hz)

The app displays electricity statistics for both forward (consumption) and reverse (generation, e.g., from solar panels) directions, broken down by daily, monthly, and yearly totals. A power usage percentage display helps identify abnormal power consumption patterns.

5.2 Automation and Smart Home Integration

• Automation Function: Set specific power or current values within the app. The device can be configured to trigger actions (e.g., send notifications) when these values are exceeded.
• Schedule Timer: Utilize the schedule timer function to automate monitoring or control based on time.
• Voice Control: The energy meter is compatible with Amazon Alexa and Google Assistant. Link your Tuya Smart account to these platforms to enable voice commands for monitoring.
• Device Sharing: Share control of your energy meter with family members or friends through the Tuya Smart App.

6. Maintenance

The Tuya Smart WiFi Energy Meter is designed for low maintenance. To ensure optimal performance and longevity:

• Keep the device clean and free from dust.
• Avoid exposing the device to extreme temperatures or humidity.
• Regularly check wiring connections for any signs of wear or looseness.
• Ensure your Wi-Fi network is stable and provides good signal strength to the device.
• Keep the Tuya Smart App updated to the latest version for new features and bug fixes.

7. Troubleshooting (FAQ)

Q1: What should I do if I can't configure the switch module?

A: Please check the following:

• Ensure the device is powered on.
• Make sure your mobile device and the energy meter are connected to the same 2.4GHz Wi-Fi network.
• Verify that your internet connection is stable.
• Double-check that the Wi-Fi password entered in the App is correct.
• Confirm that the wiring is correct according to the installation diagrams.

Q2: What devices can be connected to this WIFI Single Phase Clamp?

A: This device is suitable for monitoring various electrical circuits, including main switches, solar power generation systems, and large machinery circuits, within its specified current range (0.2-80A per channel).

Q3: What happens if the WIFI goes off?

A: If the Wi-Fi connection is lost, the energy meter will continue to function locally, but you will not be able to monitor or control it via the app. Once Wi-Fi is restored, the device should automatically reconnect to your network.

Q4: What should I do if I change the WIFI network or change the password?

A: You will need to re-connect your Wi-Fi energy meter to the new Wi-Fi network or with the new password. This typically involves putting the device back into pairing mode (by pressing the reset key for ~10 seconds) and re-adding it through the Tuya Smart App, similar to the initial setup process.

Q5: How do I reset the device?

A: Press and hold the "Reset" key on the device for approximately 10 seconds until the indicator light flashes. This will put the device into pairing mode or factory reset it, depending on the duration of the press.

8. User Tips

• CT Clamp Direction: Pay close attention to the arrow on the CT clamp. Ensure it points in the direction of current flow towards the load for accurate readings. While the meter is accurate, incorrect orientation might affect how "forward" and "reverse" measurements are interpreted by the user.
• Single Wire per Clamp: Always ensure that only one live wire is clamped by each current transformer. Clamping multiple wires can lead to inaccurate measurements.
• App Data Interpretation: The meter can measure in both "forward" (consumption) and "reverse" (generation) directions. Understand these readings to correctly interpret your energy usage and production.
