Setup
1. Initial Power-Up and Charging
The main host unit has a built-in 2000mAh lithium battery. Before first use, it is recommended to fully charge the device. Connect the provided USB Type-C cable to the main unit and a suitable USB power adapter (not included). A full charge typically takes 3-4 hours and provides approximately 6 hours of operation.

2. Installing Batteries in Wireless Sensors
Each wireless temperature and humidity sensor (slave unit) requires two AAA batteries (not included). Open the battery compartment on the back of each sensor and insert the batteries, ensuring correct polarity. The sensor will automatically power on once batteries are installed.

3. Pairing Wireless Sensors with the Main Unit
To pair the wireless sensors with the main unit:
- Ensure the main unit is powered on.
- Press the button on the main unit for 1 second. The unit will emit a buzzer sound and enter wireless pairing mode.
- For each wireless sensor (CH1, CH2, CH3), press its CH button 4 times in a row. The corresponding channel symbol (e.g., CH1) on the main unit's display will flash. If the symbol stops flashing within 20 seconds, the pairing is successful.
- Repeat the process for all three sensors.
The transmission distance between the host and slave units is approximately 30 meters indoors. In open, unobstructed areas, this distance can extend up to 60 meters.

4. Connecting to the Tuya Smart APP
To utilize the smart features and remote monitoring, download the "Tuya Smart" app on your smartphone. Follow the in-app instructions to connect your main unit to your 2.4G WiFi network (5G WiFi is not supported). Once connected, the main unit's time and date will automatically synchronize with your smartphone.

2. Using the Tuya Smart APP
The Tuya Smart APP provides enhanced control and data visualization:
- Real-time Monitoring: View all air quality and weather data remotely.
- Historical Data: Access daily, monthly, and yearly historical data curves for all parameters.
- Settings: Adjust display brightness, mute sounds, and switch temperature units between Celsius and Fahrenheit.
- Alarm Clock: Set and manage alarm clock functions.
3. Switching Temperature Units on Sensors
You can switch the temperature display unit (Celsius/Fahrenheit) directly on the wireless sensors by pressing the CH button repeatedly. Each press will cycle through the available units.
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 and sensors are not obstructed.
- Replace AAA batteries in the wireless sensors when the low battery indicator appears.
- Store the device in a cool, dry place when not in use for extended periods.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Wireless sensor not displaying data on main unit. | Sensor not paired or out of range. | Re-pair the sensor with the main unit (refer to "Pairing Wireless Sensors" in Setup). Ensure sensors are within range (up to 30m indoors, 60m outdoors). Check sensor batteries. |
| Main unit not connecting to WiFi. | Incorrect WiFi password, 5G WiFi network, or password visibility issue during setup. | Ensure you are connecting to a 2.4G WiFi network. Double-check the WiFi password. Some users have reported success by temporarily unhiding the password during the app setup process. |
| Inaccurate readings. | Sensor obstruction or environmental factors. | Ensure sensors are placed in an area with good airflow and away from direct heat sources, strong drafts, or chemical fumes. Allow the device to stabilize for a few minutes after placement. |
| Main unit screen is dim. | Backlight setting is low. | Adjust the backlight brightness via the Tuya Smart APP settings. |
