Every time you put the GoBe3 on your wrist, it may take between 30 minutes and three hours to calculate the hydration level. Poor contact between the device's sensors and the skin will increase the calculation time.
Also, if you reset the GoBe3 to factory settings or update the firmware before going to bed, hydration data may not be displayed in the mobile app or web panel until the morning, even if you wear the band overnight.
If the above factors are ruled out and hydration is still not calculated within the first two days of wearing, the reason could be a loose fit of the band.
When there is poor contact with your skin, the sensors cannot collect enough data, and the hydration calculation algorithm will not start. In this case, please check whether the device's sensor is snug enough against your skin. You may need to tighten the strap slightly. However, this should not cause discomfort. Please try tightening the strap to a comfortable position.
If these recommendations don't help, please email us at gobe@healbe.com and send a screenshot from the app showing the Hydration screen and let me now if you see any hydration information on the band's display.
