- Search for and download the Tuya Smart or Smart Life app.
- After installation, open the app and agree to the terms and privacy policy.

Step 3: Add the Device to the App
Connect to the Device
- When the app scans and detects the dehumidifier, select "Add" to add the device.
- Enter your WiFi password correctly and wait for the app to connect to the device.
- Once the WiFi light stops blinking, the device has successfully connected.
- Tap "Finish", then tap the device icon in the app to start controlling it.
Connection Tips
- Keep the dehumidifier, smartphone, and WiFi router close together to avoid signal loss.
- Only 2.4GHz WiFi networks are supported. 5GHz is not supported.
- Ensure a stable WiFi connection and enter the correct password.
- Follow all steps in the app to put the device into pairing mode.
Step 4: Complete the Setup and Start Using
After successful connection, the app will display the control interface with humidity levels and additional features.
- Press the power button to turn the dehumidifier on.
- To access full features, go to "Mode" → press “+” to add functions to the main screen.
Features on the Main Screen
1. Mode (Three Modes Available)
- Dry (Clothes Drying Mode): Runs continuously at high power and heat to quickly dry clothes, especially in humid or rainy conditions.
- Manual (Custom Humidity): Allows you to set a desired humidity level. The machine will automatically turn on/off to maintain the set level, helping to save energy.
- Comfort (Silent Mode): Operates quietly with low noise, suitable for use at night or in bedrooms to ensure uninterrupted sleep.
2. Dehumidify Set (Humidity Settings)
The machine allows users to set their desired humidity level to help control the indoor environment. Available settings include 40%, 50%, 60%, 70%, and a special continuous mode labeled "CO":
- CO Mode (Continuous – 10%): The machine runs continuously, ideal for situations that require constant dehumidification such as during prolonged rainy days, drying clothes, or in areas with very high humidity levels.
- 40%, 50%, 60%, 70% Modes: These are fixed humidity settings. When the room's humidity drops more than 5% below the set level, the machine will automatically stop to save energy. If the humidity rises more than 5% above the set level, the machine will automatically restart to maintain stable humidity.
Example: If you set the humidity level to 50%, the machine will stop when the room humidity drops to 45%; it will automatically restart when the humidity rises to 55%.
3. Anion (Negative Ion Air Purification)
The anion function generates negative ions in the air, which help eliminate odors, reduce dust, and purify the air. In addition to dehumidifying, the machine also supports improving the overall air quality in your living space.
4. Child Lock
This safety feature disables the control panel to prevent children from accidentally changing settings. It’s especially useful for households with young children. It can be activated remotely through the WiFi app (not a physical button on the control panel).
5. Cloud Timing (Timer Function)
Allows you to schedule the machine to automatically turn on or off. This helps save electricity and fits well with your daily routine.
6. Remind (Full Water Tank Alert)
When the water tank is full, the machine will stop automatically and emit a sound and light alert to prevent overflow and ensure safety.

2. Energy Saving
Connecting to WiFi allows you to proactively manage the operating time of the dehumidifier, thereby reducing unnecessary energy consumption.
- Thanks to the remote control feature, you can turn off the device immediately when it’s not needed, instead of letting it run all day.
- You can easily set a suitable operating schedule — for example, only turning the machine on at night or early in the morning when humidity levels are typically higher.
- Alternatively, you can set the device to automatically shut off once the ideal humidity level is reached, helping to prevent overuse, save electricity, and extend the lifespan of the device.
3. Monitor and Control Indoor Air Quality
When connected to WiFi, the Kosmen dehumidifier allows you to easily monitor and manage the air quality in your room via the app.
- The app displays real-time humidity levels and sends alerts when the air is too humid or too dry.
- This enables you to make timely adjustments to ensure that your living environment remains dry, fresh, and comfortable for your family.
- Maintaining ideal humidity levels also helps prevent health issues such as allergies, sinusitis, and respiratory illnesses.
4. Convenient Child Lock Feature
The Kosmen dehumidifier is not only smart but also safe for households with children, thanks to the Child Lock feature. Although there is no dedicated button on the control panel, the Child Lock can be activated remotely via the WiFi connection.
- Once activated, the control buttons are disabled, preventing children from accidentally changing settings or turning the machine on or off.
- This not only ensures the safety of your children but also protects the device from wear and tear due to frequent or incorrect operation.
