Versa 4 stopped tracking my HRV

[Gewgolf]

I have a Versa 4. The breathing rate variability appears to have stopped reporting as of 12/1. My breathing rate stopped reporting on 12/2. I can assure you I am alive and well. I have reset my Fitbit several times AND I have cleaned the sensors. Any ideas?

Hi there, @Gewgolf. It's nice to see you around the Fitbit Community Forums. Thanks for bringing this to my attention and for the troubleshooting steps you've tried. I'm sorry to hear that your Versa 4 has stopped tracking your HRV. I understand your concern, I will do my best to help you with this!

Fitbit uses the common formula called Root Mean Square of Successive Differences (RMSSD) to determine HRV from your recent heart-rate data. In the graph, your latest HRV measurement is from the longest sleep period over the past 24 hours. Only sleep periods greater than 3 hours are considered.

If your HRV hasn't been measured, see how you can improve the accuracy of your heart rate reading by following the suggestions in our help article How do I track heart rate with my Fitbit device? > How to I improve the accuracy of a heart rate reading.

On a side note, I recommend making sure that your Versa 4 is up-to-date. For more information, see Update your Fitbit device
