5. Setup
5.1. Electrical Installation
IMPORTANT: Electrical installation should be carried out by a certified electrician to ensure safety and compliance with local electrical codes. Ensure power is OFF before beginning installation.
- Mount the eMylo Smart Watt Meter & Energy Protector securely in your electrical distribution box or desired location.
- Connect the incoming live (L) and neutral (N) wires to the 'IN' terminals of the device.
- Connect the outgoing live (L) and neutral (N) wires to the 'OUT' terminals of the device, leading to your load.
- Double-check all connections for tightness and correct polarity.
- Restore power to the circuit. The device display should light up.
5.2. App Connection and Pairing
To utilize the smart features, you need to connect the device to the Tuya Smart or Smart Life app.
Figure 5.1: App connection and pairing process.
- Download the App: Turn on your mobile phone's Bluetooth. Download the "Smart Life" or "Tuya Smart" app from the App Store (iOS) or Google Play Store (Android). Register and log in to your account.
- Enter Pairing Mode: On the device, long press the button with the link symbol (usually the 'Decrease' button) for about 5 seconds until the indicator light starts blinking rapidly. If it's not blinking rapidly by default, this step will initiate the rapid blink.
- Add Device in App: Open the app. Choose the "+" icon in the upper right corner to add a device. A page will pop up indicating a device is to be added.
- Confirm Indicator: In the app, confirm that the indicator is blinking rapidly. Enter your 2.4GHz WiFi network password. (Note: Your phone should also be connected to the 2.4GHz WiFi network during pairing).
- Connect: Wait a few seconds for the device to connect. Once connected, you can remotely control and monitor your appliance freely.
6. Operating Instructions

8. Troubleshooting
If you encounter issues with your eMylo Smart Watt Meter & Energy Protector, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | No power supply; incorrect wiring. | Check main power supply. Verify wiring connections (IN/OUT, Live/Neutral) are correct and secure. Consult a qualified electrician if unsure. |
| Cannot connect to WiFi / App pairing fails. | Incorrect WiFi band (5GHz); weak WiFi signal; incorrect password; device not in pairing mode. | Ensure your WiFi network is 2.4GHz. Move the device closer to your WiFi router. Verify WiFi password. Ensure the device indicator light is blinking rapidly (long press the 'Decrease' button if not). Your phone should also be on the 2.4GHz network during pairing. |
| Device trips frequently. | Overload; short circuit; leakage current; protection thresholds set too low. | Check connected appliances for faults or excessive load. Verify there is no leakage in the circuit. Adjust protection thresholds in the app if they are set too sensitively for your application. |
| Inaccurate readings. | Improper installation; device malfunction. | Ensure wiring is correct and secure. If the issue persists, contact customer support. |
| Device shows voltage on 'N' terminal when off (for 220V 2-pole setup). | This device is designed for single-phase N and L connections. It may not fully isolate both hot lines in a 2-pole 220V application if wired incorrectly. | For 220V applications, ensure proper wiring by a qualified electrician. This device is primarily designed for single-phase (Live and Neutral) systems. If used in a 2-pole setup, ensure both hot lines are properly interrupted by external means if full isolation is required. |
