Hi all
Newby here. I have setup a few GPS trackers and managed to stream the information to and from flespi. I am now trying to calculate basic metrics like "daily mileage" and "lifetime mileage". I have gone through all the docs on here and I can't find a "101" or "tutorial" of any sorts. All the documentation online assumes that I already understand how to configure "calculators" and "invervals", but the truth is that these elements are not intuitive for a first time user. I have some knowledge of JSON but I think need a more basic "how to" guide.
