Connecting a Load:
3.2 App Installation and Pairing
- Download the eWeLink App from the App Store (iOS) or Google Play Store (Android).
- Register or log in to your eWeLink account.
- Power on the Smart Switch.
- Open the eWeLink App and tap the 'Add' button to search for devices.
- Follow the on-screen instructions to put the device into pairing mode (usually by long-pressing the reset/manual switch button until the network indicator blinks).

- After successful Wi-Fi connection, return to the eWeLink App to complete the pairing process.
3.3 Sensor Connection
Connect the temperature probe or temperature and humidity sensor to the designated sensor socket on the Smart Switch.
4. Operating Instructions
4.1 App Remote Control
Once paired, you can control the Smart Switch from anywhere using the eWeLink app. The app displays real-time temperature and humidity data (if applicable) and allows you to toggle the switch on/off.
4.2 Temperature/Humidity Control
The Smart Switch can automatically control connected devices based on set temperature or humidity thresholds. For example, you can set it to turn on a heater if the temperature drops below a certain point, or turn on a fan if humidity exceeds a limit.
4.3 Voice Control
Integrate the Smart Switch with Amazon Alexa or Google Home for convenient voice control. Use commands like "Alexa, turn on the lights" or "Hey Google, set thermostat to 25 degrees."
4.4 RF Remote Control
If you have a 433MHz RF remote control (Learning code only), you can pair it with the Smart Switch for local control. This is useful for quick access without needing your smartphone.
4.5 Timing and Scheduling
Set up various timing tasks within the eWeLink app, including single, repeat, countdown, and loop timers, to automate your devices.

6. Maintenance
The EWELINK Smart WiFi 1 Channel Relay is designed for low maintenance. Keep the device clean and free from dust. Ensure all connections are secure. Avoid exposing the main unit to extreme temperatures or humidity beyond its operating range. The waterproof temperature sensor is designed for use in wet environments, but the main switch unit is not waterproof.
7. Troubleshooting
- Device not working/pairing issues: Ensure the device is powered correctly and within range of your 2.4GHz Wi-Fi network. Double-check Wi-Fi credentials during pairing. If issues persist, try resetting the device and attempting pairing again.
- Incorrect temperature/humidity readings: Ensure the sensor is properly connected to the Smart Switch. Verify the sensor is placed in an appropriate location for accurate readings.
- RF Remote not responding: Confirm the remote is a 433MHz Learning Code type. Ensure the remote has a working battery (CR2016X2, not included). Re-pair the remote with the Smart Switch if necessary.
- Device not responding to app commands: Check your Wi-Fi connection and internet access. Ensure the eWeLink app is up to date.
8. User Tips
- When setting up temperature-based automation, ensure the target temperature values are appropriate for the connected appliance and environment to prevent unintended operation.
- For applications like controlling a 220V fan based on temperature or humidity, ensure the fan's power requirements do not exceed the switch's maximum current rating (10A).
- Regularly check the eWeLink app for firmware updates to ensure optimal performance and access to new features.
- Consider using the device's sharing function to allow multiple family members to control and monitor the connected appliances.
