Is there any way to export the sleep data from fitbit in its entirety? Including hours of sleep for each stage.

I'm using fitbit to collect data for a sleep study. When I exported the data from the app, I noticed that the sleep profile doesn't have any data from August or September. But I actually had subjects wear them for a total of twenty days in August and September.

I can see the sleep stages in the app, but not in the exported Excel.

We are also running into this same issue. Have you all found a solution? Also, when we export our data we just get sleep score data, no information on their sleep timing or duration.

I can't either. The data I exported includes deep sleep time but it is still incomplete. Do you wear the fitbit for up to14 days within month? I think it might be one reason. I wore charge6 for 16 days but it spanned Jan and Feb, so I think it might be one reason.

I really don't feel good about the use of fitbit.....two of my  charge 6 have been dysfunctional in half a year.
