Sleep data changed from Stages to Sleep patterns

[WallyBit]

Why has my sleep data changed from showing sleep stages to sleep patterns? I prefer to observe the sleep stages part of the data but have no way of changing it back to sleep stages on my fitbit.

Hello @WallyBit Welcome to the community forums! 

There are some factors that could prevent your Fitbit device to track your Sleep Stages. I'd recommend taking into consideration the following information: 

1. 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 higher on your wrist (about 2-3 finger widths above your wrist bone). The band should feel secure but not too tight.
2. If you used the Begin Sleep Now option in the Fitbit app (instead of simply wearing your device to bed). For more information on automatic sleep tracking, see How do I track my sleep with my Fitbit device?
3. If you slept for less than 3 hours.
4. If your device’s battery is critically low.

Hope this helps!
