Thanks Aran, for another great suggestion.

What would you be interested in tracking or correlating this against?

Yesss

Yes, since I have Cronic Fatigue I’m looking for a way to track time in bed / lying down just like I can track time asleep. I love how time asleep is connected to my Fitbit.

I really I could track other time intervals just the same, such as: - time in bed - time in house - time outside of house - time at work

I would like to correlate these to health measurements (HRV, blood pressure) and next day symptoms (I.e. time outside of house with next day energy levels, head pain symptoms, stomach pain symptoms, etc.)
