Q3: Can I customize the diffusion intensity for different times of the day?
A: Absolutely. Through the Bluetooth App, you can program timed cycles and intermittent bursts. This allows you to set higher intensity during peak business hours or active times at home and switch to a power-saving mode at night.
Q4: How does the noise level compare to common home appliances?
A: Operating at ≤40dB, the ST-01SH is quieter than a standard refrigerator hum. This makes it ideal for installation in quiet zones like living rooms, study areas, or premium boutique changing rooms.
