5. Initial Setup and App Pairing

To utilize the smart features of your eMylo energy meter, you need to connect it to your Wi-Fi network and pair it with the Smart Life or Tuya Smart app.

5.1 App Download and Account Creation

• Download the "Smart Life" or "Tuya Smart" app from your smartphone's app store (iOS or Android).
• Register for a new account or log in if you already have one.

5.2 Wi-Fi Connection and Device Pairing

• Ensure your smartphone is connected to a 2.4GHz Wi-Fi network. The meter does not support 5GHz networks.
• Power on the eMylo Smart Energy Meter. The Wi-Fi indicator light on the meter should start blinking rapidly. If not, press and hold the "Pair" button for 5-10 seconds until it blinks rapidly.
• Open the Smart Life/Tuya Smart app, tap the "+" icon (usually in the top right corner) to add a device.
• Select "Electrical Engineering" or "Energy Meter" from the device list.
• Follow the on-screen instructions in the app to connect the meter to your Wi-Fi network. You may need to enter your Wi-Fi password.
• Important Note: Some users have reported that pressing the "Pair" button or during the pairing process, the device may temporarily cut the output power. If your Wi-Fi router is powered through the circuit monitored by this meter, it may lose connection.
  • Workaround 1: Perform the pairing process before installing the meter in the main electrical panel, using a temporary power source for the meter.
  • Workaround 2: Use a mobile hotspot from another phone to provide Wi-Fi during the initial pairing, then switch the meter to your home Wi-Fi via the app settings once connected.
• Once successfully paired, the Wi-Fi indicator light will become solid, and the device will appear in your app.

8. Troubleshooting

8.1 Device Not Powering On

• Check the main circuit breaker for the circuit where the meter is installed.
• Verify all wiring connections (L and N) are correct and secure.
• Ensure the input voltage is within the specified range (AC 90-250V).

8.2 Unable to Connect to Wi-Fi / Frequent Disconnections

• Ensure your Wi-Fi network is 2.4GHz. The meter does not support 5GHz.
• Check the Wi-Fi signal strength at the meter's location. Move the router closer or use a Wi-Fi extender if necessary.
• Confirm your Wi-Fi password is entered correctly in the app.
• If the meter cuts power during pairing, refer to the "Wi-Fi Connection and Device Pairing" section (5.2) for workarounds.
• Try resetting the meter (power cycle) and attempting the pairing process again.

8.3 Inaccurate Readings

• Ensure the meter is correctly wired and installed according to the diagram.
• If discrepancies persist, contact customer support.

8.4 Device Turned Off via App and Cannot Be Re-enabled

If the meter's output power is cut via the app and your Wi-Fi router is on the same circuit, you will lose Wi-Fi connectivity to the meter, preventing remote re-enablement.

• Solution: Physically cycle the power to the meter (turn off and on the main circuit breaker). This will restore power and Wi-Fi connectivity.
• Alternative: If you have a mobile hotspot, connect your phone to it, then use the app to re-enable the meter.
