Personal project. Want to view/export calorie data second-by-second. Any device track this?

[akvalle26]

Currently have older device (Charge HR).  The calorie export is minute-by-minute.  (see below)

{
  "dateTime" : "10/05/16 00:00:00",
  "value" : "3.93"
},{
  "dateTime" : "10/05/16 00:01:00",
  "value" : "1.6"
}

I know the AW (apple watch) can record more granularly, especially if in workout mode.  Example:

startDate="2020-03-23 07:26:06 -0700" endDate="2020-03-23 07:27:07 -0700" value="0.321"

Question:  Do any of the latest fitbit devices have this level of granularity (in seconds)?  I don't mind doing an Data Export or hitting WebAPI (since personal use only).  But I want to make sure the device I buy has this level of granularity.

Hi @akvalle26,

Welcome to the forums!

All of our devices track calorie burn, but for the best results, we recommend getting a device that is heart rate enabled (such as Inspire HR, Charge 3, Versa family, and Ionic).

We do support granular sampling of calories burned, but not in 1second detail-level. The smallest we offer is 1minute or 15min granularity through the Get Activity Intraday Time Series endpoints.

The only data we support with 1sec or 1min detail-level sampling is heart rate, which you can see through the Get Heart Rate Intraday Time Series endpoints.

If you'd like to test the endpoints, I recommend using our Web API explorer. You can follow the steps here.
