Hello, my whoop all time write device off body. How I can calibrate sensor, or may be you can help me? I updated firmware. Only after reboot device work near 5-7 sec and again write - device off body.
Hey @StasNov,
It sounds like your WHOOP device is stuck in “off body” mode despite being worn, even after a firmware update and reboot. Here are some steps to help resolve this:
-
Ensure the device is worn snugly against your skin, about one finger-width above the wrist bone. The sensor should have good skin contact with no gaps.
-
If you wear WHOOP on your bicep, make sure the strap is tight enough to prevent false off-body detection.
-
Avoid placing the sensor over tattoos, scars, or very close to the wrist bone.
-
Reboot your WHOOP device again via Device Settings > Advanced > Reboot Device.
-
Keep the WHOOP and your phone close during these steps to maintain connection.
-
If the issue persists, try letting the battery drain fully by wearing it until it dies, then recharge fully and test again.
If you’ve done all this and the device still shows “off body,” ping support@whoop.com so a member of our Membership Services team can better assist you.
