Improving sensor-to-skin contact
Sometimes GoBe may not be able to maintain stable contact with your skin, which is required for accurate measurements. This can happen even when the band is worn properly and is usually resolved with a few simple steps.
GoBe U and GoBe3 notify you about poor sensor contact in different ways:
GoBe U and GoBe3 notify you about poor sensor contact in different ways:
GoBe3 vibrates and displays the message “Sensor doesn’t fit” on the screen
GoBe U vibrates and indicates loss of contact with an orange flashing LED indicator.
These events are also shown in the HEALBE app. They appear in the same section where other smart band notifications are collected:
In addition, a “check sensor contact” status will appear in the top bar on the main screen:
How to ensure proper sensor fit
First, make sure the smart band fits comfortably but securely. The sensor should rest against the skin without gaps, and the band should be positioned about 1–2 finger widths above the wrist bone. If it feels slightly loose, gently tighten the strap — in most cases, this is enough to restore proper contact.
In some cases, the contact quality depends on the area where the sensor is placed. Tattoos, scars, raised areas, or dense hair growth may interfere with conductivity. In this situation, try adjusting the position of the band, for example, place it on the inner side of the wrist. Many users achieve stable contact this way.
If the notification continues to appear, check the sensor for grease or other buildup that may interfere with contact and clean it:
• apply a small amount of liquid soap or dishwashing detergent to the inner side of the band,
• gently clean the sensor contacts and strap using a cotton swab,
• rinse thoroughly and dry with a soft cloth.
A light residue naturally builds up with daily wear — this is normal. Light cleaning once or twice a week helps maintain measurement accuracy.
Pay attention to when contact loss occurs:
• If it happens when you rest, your skin may be too dry, or the band may not be snug enough. Lightly moisturize the area under the sensor and wear the band for a few hours. If contact improves, regular moisturizing can be an effective solution.
• If contact is lost during movement and the strap is already snug, this may be due to individual wrist shape. In this case, you can send a photo of your wrist with the smart band to gobe@healbe.com, and we’ll suggest how to optimize the fit.
