Installation and Setup
Warning: Installation should only be performed by a qualified electrician. Ensure all power is disconnected at the main breaker before beginning installation to prevent electric shock.
1. Physical Installation
- Power Disconnection: Turn off the main power supply to your electrical panel. Verify with a voltage tester that no power is present.
- Mounting: Mount the WEM3080 meter onto a standard DIN rail within your electrical panel.
- Wiring the Meter:
- Connect the live (L) and neutral (N) wires from your main power supply to the corresponding terminals on the meter (typically marked UL and UN or L and N).
- Connect the split core Current Transformer (CT) around the live wire of the circuit you wish to monitor. Ensure the arrow on the CT points in the direction of current flow (e.g., towards the load for consumption, or away from the inverter for solar production).
- Connect the CT's output wires to the CT input terminals on the WEM3080 meter (typically marked CT).
- Antenna Connection: Screw the external WiFi antenna onto the designated connector on the meter.
- Power Restoration: Once all connections are secure and verified, restore power to the electrical panel. The meter should power on.

2. Network Configuration (Wi-Fi Setup)
After physical installation, configure the meter to connect to your Wi-Fi network and the IAMMETER cloud server.
- Download the App: Download the IAMMETER app from Google Play Store (for Android) or Apple App Store (for iOS).
- Create Account: Open the app and create a new user account or log in if you already have one.
- Add Device: Follow the in-app instructions to add your WEM3080 meter. This typically involves putting the meter into configuration mode (refer to the meter's LED indicators for status) and connecting your phone to the meter's temporary Wi-Fi hotspot, then providing your home Wi-Fi credentials.
- Cloud Connection: Once configured, the meter will connect to your home Wi-Fi and then to the IAMMETER cloud server, where it will begin uploading data.

Troubleshooting
If you encounter issues with your IAMMETER WEM3080, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Meter not powering on. | No power supply to the meter terminals (UL/UN). | Check wiring connections and ensure the circuit breaker is on. Verify voltage at the meter terminals. |
| Cannot connect to Wi-Fi. | Incorrect Wi-Fi password, meter too far from router, 5GHz network (meter supports 2.4GHz only). | Double-check password. Move router closer or use a Wi-Fi extender. Ensure your Wi-Fi is 2.4GHz. Reset meter and try setup again. |
| No data or incorrect data displayed. | CT installed incorrectly (reversed), CT not connected, meter not connected to cloud. | Verify CT direction (arrow should point towards load/grid). Check CT wiring. Ensure meter has stable Wi-Fi and cloud connection (check LED status). |
| App/Web portal not updating. | Internet connectivity issues, server maintenance. | Check your internet connection. Verify meter's cloud connection status. Check IAMMETER's service status page for any known outages. |
If the problem persists, please contact IAMMETER customer support for further assistance.
