Unable to get Sleep Stages.

[deez2020]

My sleep stages are not calculating. It shows the time I slept but not the REM, light, or deep. I just got it and it has not done it for the 5 days I’ve had it. It says “no sleep stage” for every night.

Hello @deez2020, have a warm welcome to the Fitbit Community, it's great to have you on board. It's nice to see you too @Rich_Laue, thanks for your insight about this situation. 

@deez2020, I appreciate your participation in the Forums and for sharing your experience with us.  Please note that the Fitbit app currently has in-app error notifications that provide an explanation for why you aren't receiving Sleep Stages on any given night. This is meant to provide insight into what might be occurring to cause this.The error messages are the following:

1. We need more than 3 hours of sleep to reliably calculate your sleep stages. Learn more
2. Your tracker couldn't get a consistent heart rate reading while you slept. Learn more 
3. We couldn’t generate sleep stages for this sleep. Please try again tomorrow. Learn more

When you tap on Learn more, you will be able to get more information about why your tracker didn't record sleep stages. Additionally, I'd like to suggest the following:

• For any of the nights you were expecting to see Sleep Stages, did you ever click on the "Begin Sleep Now" or "Add Sleep Log" functions within the Fitbit App?
  • This is important to note because your tracker uses auto-detection to track Sleep Stages; so there's no need to try and remember to click on anything before falling asleep! 
• Do you have at least 3 consecutive hours of sleep?
  • This is important to note because you typically won't see sleep stages if you are waking up multiple times through out the night or taking short naps.
• Your tracker's battery isn't at a critically low level prior to falling asleep.
• Your device is tracking and syncing heart rate data.
  • This is important because Sleep Stages uses a combination of your movement and heart-rate patterns. 
• Your Fitbit App is updated to the latest version.

I hope this can be helpful, give it a try and keep me posted in case you need anything else.
