HRV shows 0 ms, but Daily Readiness Score is 100

[Sambam26]

Hello Fitbit Support,

I’ve noticed that my Heart Rate Variability (HRV) consistently shows 0 ms in the app — both in the daily and weekly views.

At the same time, I regularly receive a Daily Readiness Score of 100, which should only be possible if HRV data is being recorded and processed internally.

Other health metrics like resting heart rate, breathing rate, skin temperature, etc., are updating normally and appear accurate.

I’m using a Fitbit Charge 6 with the latest firmware and have already tried the following:

Reinstalling the app

Clearing the app cache

Resyncing multiple times

My question is:

Is my HRV being tracked correctly but just not displayed in the app? And is there anything I can do to fix this display issue?

Thank you in advance for your help

Best regards,

[Joellbee]

I am having the same issue and have done all the same attempted fixes. Please help Fitbit, I do use my HRV for training purposes and not having it for the past week is throwing me off!

If you've already tried the recommended troubleshooting without success, the next step would be to contact Support (<-- click). Complete the prompt in Step 1.
