Storing and Sending Historical Data

I have a data array var dataHistoryArray = []

I then have a set interval function that runs every minute and appends the current heartRate, stepCount, and ISO Time

Notes on Step Count

Currently I am using today.adjusted.steps for the steps. This is the step count that is adjusted by the fitbit servers. I am assuming that there is some additional data processing that goes on here to determine if it is actually a step or not.

If you want to use the step count data from the watch, use today.local.step.

Memory overload

To check for memory overload issues, I added some additional GUI to show the current memory. This can be turned off in line 22 by turning production to true

const production = true // false for dev / debug releases
