My HRV suddenly drops to 0

Hi, I got my charge 2 a week ago and for the first 5 nights my hrv showed between 120 and 150ms. The last two nights it dropped to zero and I don't believe thats right.

Is there some way I can fix this or is it possible it gets fixed in a future update?

Additionally my personal zone ranges from negative 37 to positive 150? How can my personal zone start with a negative value?

Hello @SolarAtze 

Negative and zero values for HRV definitely don't sound right. 

Have you tried any troubleshooting steps yet, like restarting your Fitbit? 

Another thing to check is that your personal info in the Fitbit app is still correct. To check:

  • Tap on the You tab at the bottom of the Today page in the Fitbit app
  • Tap on Edit profile
  • Confirm that your profile information is correct, especially birth date with year
