Inspire 2 sleep tracker innacurate

[Vixo]

I haven’t had my inspire 2 very long but the sleep tracking app seems to be wildly inaccurate. I was travelling yesterday on an overnight ferry, boarding in my car at 11.15 pm and arriving in my cabin at 11.30 pm - I slept very badly and was awake and up by 5.30.  Walking around the ship, returning to my car at 7am. My sleep tracker tells me I was asleep at 10.30 untill 7.30 am and a good night!  Can it be trusted at all if it got this so wildly wrong?

Welcome to the Community forums @Vixo 

Thanks for providing the details regarding the Inspire 2.

Before considering other options, please keep in mind that there are some factors that may prevent your tracker from recording your sleep. Please make sure of the following:

• If you slept in a position that prevented your device from getting a consistent heart-rate reading or wore it too loosely. For best results, wear your device as described in this help article.
• If you slept for less than 1 hour for sleep patterns or less than 3 hours for sleep stages.
• If your device’s battery is critically low.

If you haven't done so already, please try to complete a restart procedure: 

Connect your device to the charging cable. For instructions, see How do I charge my Fitbit device?.

Try adjusting the sleep sensitivity on the Fitbit app and check if you continue to have the same problem.

In addition, please wear your device on your non-dominant hand and monitor it for the next few days. In the meantime, for the nights that don't have sleep data, you can manually log your sleep by going to the Fitbit app, tapping on the "+" icon next to the sleep tile > Add Sleep Log and entering your details.

My query was why my Fitbit recorded me as sleeping and walking at the same
time?

@Vixo thanks for getting back. 

I appreciate your feedback. Let me ask you if that happens once or did you have experienced this behavior before?

Rarely, the devices register both activities at the same time. In this case, you can manually add the activity and delete that one wrong.

In this article you can find the steps listed in order to delete the activity.
