How do the LED indicators on Shelfy work and what do they indicate?

White LED

• Flashing with pauses: Battery charging.
• Flashing (various speeds): Shelfy is in purification mode, operating based on cycles. The flashing speed corresponds to the mode: slow blinking for Eco Mode (4.5s), moderate blinking for Crisper Mode (1.5s), and fast blinking for Performance Mode (0.5)s.

Blue LED

• Flashing: Bluetooth is active and waiting for a connection.
• Steady: Bluetooth connection has been established with a smartphone.

Red LED

• Steady: Battery is almost empty (<10%). Charge the device to avoid deep discharge.

Green LED

• Steady: Battery is fully charged.

How do purification cycles relate to the LEDs?
Shelfy operates through purification cycles, alternating between periods of activity and inactivity on an hourly basis. The white LED flashes when the fan is active during these cycles. If you open the fridge and notice the fan is off, don’t worry! Shelfy is still performing its job and will resume activity automatically.

How do I charge Shelfy when the red LED turns on?
When the red LED turns on, it means Shelfy’s battery is below 10%. Remove the back casing and charge it using the provided USB-A/USB-C cable with a charger of at least 15W (5V = 3A). Lower-power chargers may take longer for a full charge. The green LED will indicate that the battery is fully charged.

What should I do if my LED indications seem unusual?
If the LEDs do not behave as expected, try resetting the device by holding the button for 10 seconds until the LED flashes orange and then turns off.
