Operating Instructions

Display Modes

The main unit features a 2.8-inch color digital display with multiple display modes. You can switch between modes to view different information:

  • Air Quality Parameter Display: Shows real-time readings for PM2.5, PM1.0, PM10, CO, CO2, TVOC, and HCHO, along with a color-coded air quality indicator.
  • Time and Subunit Data Display: Shows current time, date, and temperature/humidity readings from up to 5 connected subunits.

Celsius/Fahrenheit units for temperature can be switched according to your preference.

Maintenance

To ensure optimal performance and longevity of your air quality monitor:

  • Keep the device clean by wiping it with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
  • Ensure the ventilation holes on the main unit are not obstructed to allow for proper air circulation and heat dissipation.
  • Replace subunit AAA batteries as needed to maintain continuous monitoring.
  • Store the device in a cool, dry place when not in use for extended periods.

Troubleshooting

  • No Display/Device Not Turning On: Ensure the main unit is fully charged. If using subunits, check if AAA batteries are correctly installed and not depleted.
  • Inaccurate Readings: Ensure the device is placed in an area with good air circulation, away from direct drafts, heat sources, or strong chemical fumes. Allow the device to stabilize for a few minutes after powering on.
  • APP Connectivity Issues: Verify that your main unit is within range of your Wi-Fi router and that your Wi-Fi network is stable (2.4GHz only). Restart the device and your router, then attempt to reconnect via the Tuya app.
  • Alarm Sounds Frequently: Check the displayed parameter values. If they are consistently high, investigate the source of air pollution in your environment. You may need to adjust alarm thresholds in the app if they are too sensitive for your environment.

User Tips

  • Optimal Placement: For the most accurate readings, place the main unit and subunits in central locations within the rooms you wish to monitor, away from windows, doors, and ventilation outlets that might skew readings.
  • Leverage APP Monitoring: Utilize the Tuya app to its full potential. Regularly check historical data to identify trends in air quality and make informed decisions about ventilation or air purification.
  • Battery Life: While the main unit has a built-in rechargeable battery, remember to keep spare AAA batteries for the subunits to ensure continuous, uninterrupted monitoring across all locations.
  • Ventilation is Key: If the monitor consistently shows high levels of pollutants, consider increasing ventilation by opening windows or using air purifiers.
