Sleep stages for the Fitbit one

[soupermom]

I read on the blog that "sleep stages" is NOT available on the FitBit one! But "Sleep Insights" will work on all but the Zip.
See below:

Sleep Stages and Sleep Insights are available globally on Alta HR and Blaze and will be available on Charge 2 in April 2017. Both features are viewable in the Fitbit app—which is compatible with Android, iOS, and Windows devices—and on your Fitbit.com dashboard.

Sleep Stages will work with Fitbit Alta HR, Blaze, and Charge 2 devices. Sleep Insights will be available in the Fitbit app and work with all Fitbit devices except Zip, which does not track sleep.

I don't know why the sleep stages is not available for the one! Will it be in a future update? Does anyone know?

Sleep stages depend on tracking your heart rate so it won't be coming to the fitbit One.
