[AchyLegs]

Why has my heart rate varibility not working?  It worked fine for the first week not not working.  Have done all the basics like restart and cleaning sensors.  

Little help here.

Welcome to the Community Forums, @AchyLegs.  

Thank you sharing this information about what you've been experiencing with your Charge 5 and the troubleshooting steps that you already tried. 

In addition to the restart you mentioned, 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. 
5. Keep the Fitbit app updated to the latest version available. 

Hope this helps, I'll be around.
