6. Installation
The Yasorn Smart Energy Meter is designed for 35mm DIN rail mounting.
6.1 Physical Installation
- Power Disconnection: Before starting, ensure the main power supply to the circuit where the meter will be installed is completely disconnected.
- Mounting: Clip the meter onto a standard 35mm DIN rail within your electrical panel.
- Wiring: Refer to the wiring diagram below and the labels on the meter for correct connections.
6.2 Wiring Diagram
Connect the incoming live (L in) and neutral (N in) wires to the top terminals. Connect the outgoing live (L out) and neutral (N out) wires to the bottom terminals, leading to the load.

- Secure Connections: Ensure all wire connections are tight and secure to prevent loose contacts and overheating.
- Power Restoration: Once installation is complete and verified, restore power to the circuit. The meter's display should illuminate.
7. App Setup and WiFi Connection
To utilize the smart features, you need to connect the meter to your home Wi-Fi network via the 'Smart Life' or 'Tuya' app.
- Download App: Download the 'Smart Life' or 'Tuya' app from your smartphone's app store (available for iOS and Android).
- Register/Login: Open the app and register for a new account or log in if you already have one.
- Add Device: Tap the '+' icon in the top right corner of the app to add a new device. Select 'Electrical Engineering' > 'Energy Meter (Wi-Fi)'.
- Pairing Mode: On the meter, press and hold the 'Pair' button (usually located near the WiFi indicator) until the WiFi indicator light starts blinking rapidly. This indicates pairing mode.
- Connect to WiFi: In the app, confirm the indicator is blinking rapidly. Enter your 2.4 GHz Wi-Fi network name and password. (Note: 5 GHz Wi-Fi networks are not supported).
- Completion: The app will search for and connect to the device. Once connected, the WiFi indicator on the meter will become solid, and the device will appear in your app's device list.
8. Operating Instructions

10. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Meter display is off | No power supply to the meter. | Check the main power supply and wiring connections. Ensure power is restored to the circuit. |
| Cannot connect to Wi-Fi / App | Incorrect Wi-Fi password; 5 GHz Wi-Fi network used; Meter not in pairing mode; Weak Wi-Fi signal. | Ensure you are using a 2.4 GHz Wi-Fi network. Verify the Wi-Fi password. Put the meter into pairing mode (blinking Wi-Fi indicator). Move the meter closer to the router or improve Wi-Fi signal strength. |
| Inaccurate power readings in app | App synchronization issue; Firmware outdated. | Restart the app. Check for app updates. Ensure the meter's firmware is up to date via the app settings. If issues persist, contact support. |
| Remote control not working | No internet connection on phone or meter; Meter is offline. | Verify your phone's internet connection. Check if the meter's Wi-Fi indicator is solid (connected). If not, re-establish Wi-Fi connection. |
