Avg daily resting heart rate download.

[jimojimo]

Hi,

I have downloaded my raw data and see a lot of heart rate data.  Each point has a sort of “confidence” rating (can’t recall the exact term).  What I need is the avg resting rate per day. 

There must be some special algorithm Fitbit uses to arrive at avg daily resting rate, I’m wondering if that is non-proprietary information that can be shared?  I tried reverse engineering by taking the average low rate, grouping by standard deviations under the daily average, also tried using just the high confidence points, tried all sorts of things, but could never get it to match the four or so months of data I see in the Fitbit app’s daily resting rate graph.

also, a related question—is the tome in the raw output UTC or converted to the zone in my device?

Has anyone figured this out, or, more simply, will fitbit offer this summarized data in the download?

See How is resting heart rate measured?

That is all you will get from Fitbit about its calculation.

Hi there

How did you download your raw data.  I haven't been able to figure that out.

Thanks

If you're a developer, you can use the web-api to get it.

(I've recently downloaded all of mine, along with body weight, body fat and activity minutes.)

It didn't improve my confidence about resting heart rate values, unfortunately, but it did give me a long list of numbers going back to March 2016.

The alternative is to use Fitbit's "download all my data" link https://help.fitbit.com/articles/en_US/Help_article/1133

Which will give you a massive zip file that has absolutely everything, but doesn't summarise it so you'd have to do a few days of number crunching.
