The sensor is shown discreetly placed in a living room setting, demonstrating how the device connects to a mobile application for real-time updates and alerts.

• Open the app and select your TH02 Pro device.
• View current temperature and humidity readings.
• Access historical data graphs.

3.3. Smart App Notifications

Set custom temperature and humidity ranges within the app. If the readings go outside these predefined ranges, you will receive an instant notification on your smartphone. This feature is useful for monitoring conditions in sensitive areas like baby rooms, wine cellars, or greenhouses.

3.4. Smart Scene Integration

The TH02 Pro can be integrated with other smart devices through the Tuya Smart/Smart Life app to create automated scenes.

This diagram demonstrates the smart scene functionality. When the temperature exceeds 26°C, the air conditioner automatically turns on. When humidity drops below 50%, the humidifier activates. The Zecamin TH02 Pro acts as the central sensor for these automated actions, integrating with other smart home devices.

Example:

• If temperature exceeds 26°C, automatically turn on a smart air conditioner.
• If humidity drops below 50%, automatically turn on a smart humidifier.
