Inspire HR won't record all sleep information

[Trebor48]

My Fitbit only showed 3hr 49min sleep last night whereas my Garmin showed 6hr 10min. They’ve been within 20min generally so not sure what happened.

Welcome to the Community, @Trebor48.

I am sorry for the delay in respond, due to recent events affecting our operations, support options are limited and wait times are longer than usual. 

Now about your sleep issue, if your tracker isn't recording this information completely, I recommend trying the following:

1. Make sure to not take off your tracker during the night.
2. Do you remember being awake during the night? If yes, that solves it! Keep in mind that your tracker will detect if you are awake and will stop the sleep tracking process. If no, proceed to step three.
3. Restart the tracker. See instructions in the help article: How do I restart my Fitbit device?.
4. Confirm that the tracker is snug on your wrist (with an HR tracker, the lights shouldn't be visible).
5. Try sleeping with the tracker on your non-dominant hand.
6. If the setting was set to sensitive, please switch it to normal. 
7. If steps 1-6 do not solve the issue, I suggest manually editing the sleep log to reflect the time slept. See instructions in the article: How do I edit my sleep history in the Fitbit app?.​

Let me know the outcome. 🙂
