5.3. App Control and Monitoring

Through the Smart Life/Tuya Smart app, you can:

  • View real-time temperature and humidity readings remotely.
  • Access historical data and trends.
  • Set up alerts for temperature or humidity exceeding predefined ranges.
  • Create smart automation routines (e.g., turn on a humidifier when humidity drops below a certain level).

5.4. Voice Commands

Once integrated with Alexa or Google Home Assistant, you can use voice commands to inquire about the current temperature and humidity. Examples:

  • "Alexa, what's the temperature in the living room?"
  • "Hey Google, what's the humidity in the bedroom?"

6. Maintenance

6.1. Cleaning

To clean the sensor, gently wipe the surface with a soft, dry cloth. Do not use abrasive cleaners, solvents, or immerse the device in water, as this can damage the electronics and sensor components.

7. Troubleshooting

  • Device not turning on: Check battery installation and ensure batteries are fresh.
  • No display: Ensure batteries are correctly inserted and charged. Touch the top of the device to activate the backlight.
  • Cannot connect to WiFi:
    • Ensure your WiFi network is 2.4GHz. 5GHz networks are not supported.
    • Check if your WiFi password is correct.
    • Make sure the sensor is within range of your WiFi router.
    • Try resetting the sensor (refer to the PDF manual for specific reset instructions if available).
    • Restart your router and try pairing again.
  • Inaccurate readings:
    • Ensure the sensor is not placed near heat sources, direct sunlight, or in drafts.
    • Allow the sensor to stabilize for at least 30 minutes after placement or battery change.
  • Voice assistant not responding:
    • Verify that the Smart Life/Tuya Smart skill is enabled and linked in your Alexa/Google Home app.
    • Ensure the sensor is named clearly and uniquely in the Smart Life app.
    • Try rediscovering devices in your Alexa/Google Home app.

8. User Tips

  • Optimal Placement: For the most accurate readings, place the sensor in a central location in the room, away from windows, doors, and direct airflow from HVAC systems.
  • Automation: Leverage the Smart Life app's automation features to create rules based on temperature and humidity. For example, automatically turn on a smart fan if the temperature exceeds a certain threshold, or a smart humidifier if humidity drops too low.
  • Battery Life: To maximize battery life, avoid frequent backlight activation and ensure a strong WiFi signal to minimize connection attempts.
