3. Setup

3.1 Physical Installation and Wiring

1. Mounting: Securely mount the Wifi Energy Meter unit onto a standard 35mm DIN rail in your electrical panel.
2. Power Connection: Connect the main power lines (Neutral, Phase A, Phase B, Phase C) to the designated N, VA, VB, VC terminals on the top of the meter. Ensure all connections are tight and correct according to local electrical codes.
3. Current Transformer (CT) Connection: Connect the three Current Transformers to the IA+, IA-, IB+, IB-, IC+, IC- terminals at the bottom of the meter. Ensure correct polarity (indicated on the CTs) and match each CT to its corresponding phase wire. The CTs should be clamped around the load wires, not the neutral wire.
4. Dry Contact Output (Optional): If external device control is desired, connect the 16A dry contact output terminals to the control circuit of the device.

3.2 App Connection

1. Download App: Download the "Tuya" or "Smart-Life" app from your mobile device's app store (available on iOS and Android).
2. Register/Login: Open the app and register for a new account or log in with an existing one.
3. Add Device: Power on the Wifi Energy Meter. The device will typically enter pairing mode automatically (indicated by a blinking LED). In the app, tap the "+" icon to add a new device. Select "Electrical" > "Power Monitor" or "Energy Meter".
4. Wi-Fi Configuration: Follow the in-app instructions to connect the device to your 2.4GHz Wi-Fi network. Enter your Wi-Fi password when prompted.
5. Device Renaming: Once connected, you can rename the device for easier identification within the app.

4. Operating Instructions

4.1 Real-time Monitoring

• Open the Tuya/Smart-Life app and select your HOgardenME Power Monitor.
• The main screen will display real-time data for voltage, current, active power, power factor, and frequency for each phase.
• Navigate through the app interface to view historical consumption and production trends, broken down by hour, day, and month.

4.2 Remote Control and Automation

• Remote On/Off: If you have connected an external device to the 16A dry contact, you can remotely switch its on/off status via the app.
• Schedules: Set up custom schedules within the app to automate the on/off operation of connected devices at specific times.
• Voice Control: Integrate the Tuya/Smart-Life app with popular voice assistants (e.g., Amazon Alexa, Google Assistant) to control the power monitor and connected devices using voice commands.
• Automation Scenes: Create smart scenes to trigger actions based on various conditions, such as power consumption thresholds or time of day.

4.3 Bidirectional Measurement

For installations with solar panels or other energy generation systems, the HOgardenME Power Monitor supports bidirectional measurement. This allows you to monitor both the energy consumed from the grid and the energy produced and fed back into the grid, providing a complete picture of your energy flow.

5. Maintenance

• Cleaning: Keep the device clean and free from dust using a dry, soft cloth. Do not use liquid cleaners.
• Ventilation: Ensure proper ventilation around the unit to prevent overheating.
• Firmware Updates: Regularly check the Tuya/Smart-Life app for available firmware updates to ensure optimal performance, security, and access to new features.
• Connection Inspection: Periodically inspect all wiring connections for tightness and integrity to prevent loose connections or potential hazards.

6. Troubleshooting

• No Power/Display:
  • Check the main power connections to the N, VA, VB, VC terminals.
  • Verify that the circuit breaker supplying power to the device is in the ON position.
• No App Connection:
  • Ensure your Wi-Fi network is 2.4GHz. The device does not support 5GHz Wi-Fi.
  • Verify that the correct Wi-Fi password has been entered in the app.
  • Move the device closer to your Wi-Fi router to improve signal strength.
  • Restart the power monitor by cycling its power, then attempt the pairing process again.
• Incorrect Readings:
  • Verify that the Current Transformers (CTs) are connected with the correct polarity (indicated by arrows or markings on the CTs).
  • Ensure each CT is clamped around the correct phase wire (IA to Phase A, IB to Phase B, IC to Phase C).
  • Make sure the CTs are fully closed and securely clamped around the wires.
• Overload Alarm Triggered:
  • The device's overload protection has activated. Check the connected loads and reduce power consumption if it exceeds the configured limits.
  • Review the overload settings in the Tuya/Smart-Life app.
