Blaze shows large missing period from sleep at night

[Christopher76]

I went to bed last night shortly after midnight and then got up this morning after 7:30 am. When I synced my Blaze to the FitBit app on my phone, it shows two sleep periods:

Bedtime - 12:19 am

Wake up - 2:23 am

NO ACTIVITY RECORDED

Bedtime - 5:04 am

Wake up - 7:40 am

In each of the of sleep periods, it does not record/show the any sleep stages (REM/Light/Deep).

The heart rate log was recording all night; so it isn't an issue that the Blaze wasn't working or that it could not detect my heart rate.

Why does the Blaze think that I was up and awake between 2:23 am and 5:04 am? I was asleep the whole night, and I do not suffer from sleep walking.

A warm welcome to the Community @Christopher76 and thanks for the information. Have you tried to restart your tracker? If you haven't, I recommend restarting your Fitbit and test it. Also, take a look at this post where our friend @FerdinandFitbit is providing information about the sleep feature.

Let me know the outcome.
