Luxe won't track my sleep times accurately

[LuxeGma]

My Luxe fitbit records my total hours of sleep, but on several occasions the Fitbit App breaks up my sleep into two periods for the same day.  ie.   6 hours with data, and then because I was awake it then tracks a separate 1 1/2 hour without any data.   I have also had a sleep of less than 5 hours but more than 3 hours and the app does not provide any data other than total hours asleep

What drives the app to separate a nights sleep.   I do have some nightly period of being awake for an hour or more, but the app sometimes separates the sleep periods and sometimes combines

Looking to see if this is an issue with the app, or the Luxe.

Hi, @LuxeGma, welcome to the community, Sleep tracking is a complex function, and you may find this article helpful How do I track my sleep with my Fitbit device? Note the advice about normal/sensitive settings. If you are a restless sleeper this may have an impact on your data.

I hope this helps, let us know how you get on.
