The script I posted, runs in the R language and environment, all free and downloadable. It takes in one or more Sense yearly downloads with 1 hour resolution. R is an open-source statistical language that is taught in virtually all non-comp-sci focused data science courses today.
You can find the base R language here
A great IDE environment for R is R-Studio. The company that developed R-Studio offers a free version that is more than enough for most users.
My script will require a little customization for your specifics, plus will require downloading some additional packages (reader, ggplot2), but R-Studio will help you with that.
If you have done some coding before, give it a try. There are plenty of videos and tutorials on how to use R.
