FitBit Sleep tracking showing weird charts

[TondoS]

Latest FitBit version, Pixel Watch 2, showed me this

Hello @TondoS 

It looks like your Pixel Watch didn't track your sleep stages, so you got the basic sleep information charts. I've had this happen to me once.

Out of curiosity, are your sleep start & end times correct? Did you spend 19+ hours in bed?

If your sleep start / wake times are not correct, you can tap on the 3 vertical dots in the upper right and select Edit sleep. Correct the times as needed.

Hey,

They are not, I surely didn't sleep 19+ hours.

How is editing my sleep supposed to help with this issue?

BTW it happened multiple times this month, for example today

Hello @TondoS 

I suspect you got the basic sleep graph in your first screenshot because of the length of time - 19+ hours.

Editing the sleep times will adjust the data range that algorithm uses to generate the sleep data. However, since the screenshot you shared initially was from 25 Aug 2024, I'm not sure that making an adjustment now will generate the sleep stages graph since it's been over a week.

I don't know why you're having a problem generating sleep stage graphs. Are you seeing any other issues with heart rate tracking? Your Pixel Watch uses the heart rate sensor (green light on the back of the device) for sleep tracking.

Hey,

No issues with HR. Or at least I haven't discovered them yet. Quite the contrary, I was doing stress exercise at my cardiologist. It took like 15 minutes and all the time Pixel Watch measured correct hearth rate (+/- 2).

Hello @TondoS 

Thank you for the update and letting us know that your Pixel Watch was correctly tracking your heart rate.

Are you still seeing the basic sleep graphs? By any chance, have you tried moving your watch to the inside of your wrist at night? Some users found that wearing their Fitbits on the inside of their wrist improved their sleep tracking and they got their sleep stage graphs.

Hello @RiekoC ,

Yes, I still see this from time to time. Plus this strange behavior
