• Remote ON/OFF: Use the main switch toggle in the app to turn connected devices on or off.
• Temperature/Humidity Monitoring: View real-time temperature and humidity readings.
• Electricity Statistics: Access the 'Energy' tab to view current power, current load, and cumulative power data by day, month, or year.
• Auto Mode: Set specific temperature or humidity ranges for automatic device activation/deactivation. For example, turn on heating if temperature drops below 76°F and turn off if it rises above 85°F.
• Timing: Configure countdown timers, single-event timers, or recurring schedules for your devices.
• Smart Scenes: Create automation rules where the switch's temperature or humidity readings trigger actions on other Tuya-compatible smart devices.
• Device Sharing: Use the 'Share Device' function in the app to allow family members to control the switch.

4.2 Voice Control

The smart switch is compatible with Amazon Alexa, Google Home, and Google Nest. To enable voice control:

1. Link your Tuya Smart / Smart Life account to your Amazon Alexa or Google Home app.
2. Discover new devices.
3. You can then use voice commands such as:
   • "Alexa, turn on [Device Name]"
   • "Hey Google, what is the temperature of [Device Name]?"

4.3 Remote Control Matching (Optional, for RF-enabled models)

If your model supports RF remote control, follow these steps:

1. Matching: Hold the manual switch on the device for 3 seconds until the RF pairing indicator (blue light) turns on. Then, long press the desired button on your remote control. Release the remote control button once matching is successful.
2. Clear Code: Long press the manual switch for 15 seconds (the RF pairing indicator will be always on). Release the manual switch when the RF pairing indicator (blue light) turns off and then flashes rapidly 5 times. This clears all paired remote controls.

Note: Remote control functionality is only available with RF function switch/module reference.

6. Maintenance

To ensure optimal performance and longevity of your smart switch:

• Keep the device clean and free from dust. Use a dry, soft cloth for cleaning.
• Avoid exposing the device or sensor to direct sunlight, extreme temperatures, or high humidity for extended periods.
• Do not attempt to disassemble or repair the device yourself. This may void any warranty and could lead to damage or injury.

7. Troubleshooting

Common Issues and Solutions:

• Device not connecting to Wi-Fi:
  • Ensure your Wi-Fi network is 2.4GHz. The device does not support 5GHz networks.
  • Check your Wi-Fi password for accuracy.
  • Make sure the device is in pairing mode (red light blinking fast). If not, perform a reset.
  • Move the device closer to your Wi-Fi router.
  • Check your router settings to ensure it's not blocking new devices (e.g., MAC filtering).
• App not finding the device:
  • Confirm Bluetooth is enabled on your smartphone during the pairing process.
  • Ensure the device is powered on and in pairing mode.
  • Try restarting the app and your smartphone.
• Inaccurate temperature/humidity readings:
  • Ensure the sensor is not obstructed or placed in an area with extreme localized conditions (e.g., direct heat source, draft).
  • Allow some time for the sensor to stabilize after initial setup or relocation.
• Voice control not working:
  • Verify that your Tuya Smart / Smart Life account is correctly linked to your Alexa or Google Home app.
  • Ensure the device name used in voice commands matches the name set in the app.
  • Check your internet connection.

Accessing App Settings and FAQ:

For further assistance or to access detailed settings and FAQs within the app, navigate to the homepage of the Tuya Smart / Smart Life app and click the icon in the lower right corner of the interface (often a 'Me' or 'Profile' icon) to enter the settings menu.

8. User Tips

• Optimal Sensor Placement: For the most accurate readings, place the temperature and humidity sensor in a location that represents the general environment you wish to monitor, away from direct sunlight, vents, or heat sources.
• Automate with Scenes: Leverage the 'Smart Scene' feature in the Tuya app to create powerful automations. For example, set up a scene to turn on a humidifier when humidity drops below a certain percentage, or activate a fan when the temperature exceeds a threshold.
• Power Monitoring Insights: Regularly check the electricity statistics to understand the power consumption patterns of your connected appliances. This can help identify energy-saving opportunities.
