Setup Instructions

1. Wiring the Smart Switch

The Smart Switch supports various input voltages: DC/AC 7-32V, AC 85-250V, or Micro USB 5V. Ensure you select the correct model for your power supply. The output is signal only, meaning it acts as a relay to control an external circuit, not to directly power a device.

Figure 5: Wiring Diagram for DC 7-32V Smart Switch. Input DC 7-32V. Output AC 90V-250V/10A or DC 0-30V/10A via NO, COM, NC terminals.

Wiring Steps:

1. Power Input: Connect your power source (DC/AC 7-32V, AC 85-250V, or Micro USB 5V) to the corresponding input terminals on the Smart Switch. Refer to Figure 5 for DC 7-32V wiring.
2. Load Connection: Connect the device you wish to control to the relay terminals (NO, COM, NC).
3. Sensor Connection: Plug the temperature and humidity sensor probe into the dedicated sensor socket on the Smart Switch.

2. App Installation and Pairing

1. Download eWeLink App: Download the free eWeLink app from the iOS App Store or Google Play Store.
2. Register/Login: Open the app and register for a new account or log in if you already have one.

Troubleshooting

Device Not Connecting to Wi-Fi:

1. Check Wi-Fi Band: Ensure your router is broadcasting a 2.4GHz Wi-Fi signal. The device does not support 5GHz Wi-Fi.
2. Wi-Fi Password: Double-check that you are entering the correct Wi-Fi password.
3. Router Proximity: Move the Smart Switch closer to your Wi-Fi router during the pairing process.
4. Reset Device: Press and hold the reset/manual switch button on the device until the network indicator blinks rapidly to re-enter pairing mode.
5. Router Settings: Some routers may require disabling AP isolation or enabling UPnP for smart devices. Consult your router's manual.

Inaccurate Temperature/Humidity Readings:

1. Sensor Placement: Ensure the sensor probe is placed in an area where it can accurately measure the environment, away from direct heat sources, drafts, or moisture.
2. Sensor Connection: Verify that the sensor probe is securely plugged into the Smart Switch's sensor socket.
3. Environmental Factors: Extreme conditions or rapid changes can temporarily affect sensor accuracy. Allow time for readings to stabilize.

Voice Control Not Working:

1. Account Linking: Ensure your eWeLink account is correctly linked to your Amazon Alexa or Google Home account.
2. Device Naming: Use simple, recognizable names for your devices in the eWeLink app.
3. Internet Connection: Verify that both your Smart Switch and your voice assistant device have a stable internet connection.

User Tips

• Optimal Sensor Placement: For the most accurate readings, place the temperature and humidity sensor away from direct sunlight, heating/cooling vents, or areas with stagnant air.
• Automate for Efficiency: Utilize the Auto Mode to maintain desired environmental conditions, which can help save energy by only activating appliances when needed.
• Regular App Checks: Periodically check the eWeLink app for new features or updates that can enhance your device's functionality.
