6. Operating Instructions
6.1. App Remote Control
Use the dedicated smart home application (e.g., Tuya Smart app or your Matter-compatible app) on your smartphone or tablet to control the blinds:
- Open the app and select your blinds motor.
- Use the up/down arrows to move the blinds.
- Tap the "Favorite Position" button to move the blinds to your pre-set favorite position.

- "Alexa/OK Google, open the curtains."
- "Alexa/OK Google, close the blinds."
- "Alexa/OK Google, set the blinds to 50%. "

6.3. Timed Control and Automation
Set schedules for your blinds to open or close automatically:

6.4. Battery Level Monitoring
The app provides a real-time display of the motor's battery level, allowing you to know when it's time to recharge.

7. Maintenance
- Charging: Recharge the motor when the battery level is low, indicated by the app. Use the provided Type-C cable and a DC5V power adapter.
- Cleaning: Keep the motor and blind mechanism free from dust and debris. Use a soft, dry cloth for cleaning. Do not use harsh chemicals or abrasive materials.
- Environmental Conditions: The motor has an IP44 protection level, meaning it is protected against solid objects larger than 1mm and splashing water from any direction. Avoid exposing it to heavy rain or submerging it in water.
