4. Setup and Installation

The WEBN Smart Energy Meter is designed for DIN rail mounting within an electrical panel. Ensure all local electrical codes and regulations are followed during installation.

4.1 Physical Installation

Mount the device on a standard 35mm DIN rail. Connect the input (IN) and output (OUT) terminals according to your electrical system's single-phase wiring diagram. The device is typically installed in series with the main circuit breaker.

4.2 App Setup and Wi-Fi Connection

To utilize the smart features, download the "Smart Life" or "Tuya Smart" app from your mobile app store. Follow these steps to connect the device to your Wi-Fi network:

1. Ensure your mobile device is connected to a 2.4GHz Wi-Fi network. 5GHz networks are not supported for initial pairing.
2. Open the Smart Life/Tuya Smart app and tap "Add Device".
3. On the meter, press and hold the "SET" button (or the Wi-Fi Connect Key, typically the green up arrow) for 5-10 seconds until the Wi-Fi indicator light starts flashing rapidly.
4. In the app, select "Electrical" then "Breaker" or "Smart Meter".
5. Confirm the indicator light is blinking rapidly in the app.
6. Enter your 2.4GHz Wi-Fi network password.
7. The app will search for and add the device. Once added, you can rename it.

5. Operating Instructions

5.1 Manual Operation

• ON/OFF Button (Red Power Icon): Press to manually switch the power on or off.
• SET Button (Green "SET"): Press to cycle through display modes or enter settings.
• Up/Down Arrows (Green Triangles): Use to adjust values when in settings mode. The Up arrow also functions as the Wi-Fi Connect Key.

5.2 App Control and Monitoring

Once connected to the Smart Life/Tuya Smart app, you can access various functions:

• Power Consumption Statistics: View daily, monthly, and yearly energy usage.
• Real-time Data: Monitor current voltage, current, and active power.
• Remote ON/OFF: Control the power supply remotely from anywhere.
• Prepaid Functionality: Manage energy credit and automatic shutdown when credit runs out.
• Timer Function: Set schedules for automatic power on/off (Timing Mode, Countdown Mode, Cycle Timing).
• Protection Settings: Adjust thresholds for overvoltage, undervoltage, overcurrent, and leakage protection.

Figure 5.2.1: Screenshot showing the "Three Timing Modes" feature in the app, allowing users to set schedules for power on/off.

Figure 5.2.2: Example of automated appliance control, demonstrating how the app can be used to schedule devices like a toaster to turn on at a specific time.

5.3 Setting Protection Values via App

You can customize the protection thresholds directly from the Smart Life app:

• Overvoltage Protection: Set the maximum voltage threshold (e.g., 250V-300V).
• Undervoltage Protection: Set the minimum voltage threshold (e.g., 150V-190V).
• Overcurrent Protection: Set the maximum current threshold (e.g., 1A-63A).
• Leakage Protection: Set the leakage current threshold (e.g., 10mA-100mA).
• Power-up Protection Delay: Configure the delay before power is restored after a trip.
