Sense only giving basic sleep

[pastimz]

Last 4 nights I've only gotten basic sleep. I've uninstalled the app and reinstalled it, cleaned the back of the Sense, know how to wear it, etc. Fitbit user since early 2016. What are your suggestions.

@pastimz , A warm welcome to the Community ! Thank you for your message and efforts. 

The following conditions can prevent sleep phases from being recorded:

- You record your sleep using the app instead of the tracker's automatic sleep detection.
- The tracker's battery is almost empty when you go to bed (below 25%). This prevents regular heart rate recording.
- You use the metal wristband while sleeping.
- You sleep less than 3 hours.
- The wristband is too loose or too tight on your wrist. You should be able to insert your index finger between the wristband and your arm without much resistance so that your heart rate is regularly recorded and sleep phases can be detected.
