Charge 5 won't track my HRV accurately

[CilP]

The HRV has yet to work on my Charge 5. What do I need to do other than wear my device 24/7 to get HRV to work??

Hi, @CilP , HRV is only detected over night.  The Fitbit needs to be able to get consistent heart rate readings during sleep for at least several days in order to establish a baseline for you.  When you wear your Fitbit to bed make sure your Fitbit is on snuggly (so it doesn’t roll around on your wrist) but not so that it feels tight.

Are you getting “sleep stages” on your Fitbit?  If so that indicates that the heart rate reading is consistent, and in that case you should soon be able to see the HRV stat, once it has collected enough data.

I hope this helps.  Welcome to the forums!

Welcome to the Fitbit community, @CilP!

Adding to what @Julia_G already has mentioned, please check if HRV is available in the country you're living:

@Talahthas , good thinking!

Hi @CilP. A warm welcome to the Fitbit community forums. 

Thank you sharing this information about what you've been experiencing with your Charge 5. 

As @Julia_G and @Talahthas  mentioned before, please keep in mind the following to make sure you see your health metrics data:

• Wear your device for at least 1 full day (during the day and to sleep at night). Check your stats after you wake up in the morning. Note: skin temperature requires 3 nights of data.
• Make sure the back of your device is in contact with your skin. The band should be snug but not constricting. If you experience any discomfort, loosen the band, and if it persists give your wrist a break by taking it off.
• Most metrics require at least 3 hours of quality sleep. If you move a lot during your sleep or the sleep session is too short, you might not get a reading.

For more detailed information, see What should I know about health metrics in the Fitbit app? In case the HRV is being tracked but it's not being shown in the app, please try the following steps as well: 

1. Log out from the Fitbit app.
2. Clear Cache and Cookies for the Fitbit app on the phone's settings. 
3. Restart your phone. 
4. Log back in and check if you're able to see your information properly. 

Regarding the Readiness Score, make sure to follow all the recommendations listed here to receive this information and to keep the Fitbit app updated to the latest version available.
