How do I turn on and charge my ShowerStar?
To turn on your ShowerStar, press and hold the operation button for 3 seconds. The LEDs will illuminate RED, GREEN, and BLUE to confirm the device is on.

Charging your ShowerStar
When you first receive your ShowerStar, you must charge it for at least 4 to 6 hours before use.
-
Connect the provided USB Type-C cable to the charging port on the ShowerStar.
-
Connect the other end to any 5VDC phone charger or USB power source.

Battery life
The battery will typically last for 6 to 8 months. This duration depends on several factors:
-
Usage: How many showers are taken per day.
-
Settings: The brightness and number of alerts configured.
-
Connectivity: How often you connect the ShowerStar App to the device.
Note: A good rule of thumb is at least 8 months of battery life, assuming 4 showers per day. Fewer showers and less intrusive alerts will extend battery life.
