@Redbrick, I don't use tesla-apiscraper (I just started using Teslamate about a month ago) but I believe most if not all of these types of applications work pretty much the same way in that they collect and log data going forward from the time that you started using the application. The data gets stored in a database which allows you to go back and see historical data and trends but only back to the point that you started using the application. So if you started using the application 7 days ago, you could go and look at the data for the past 7 days, but there is no way to go back and see the data for 8 days ago because it was never captured and saved into the database. To get the 90 selection you mentioned to actually view the last 90 days, you would have had to have the application up and logging over the past 90 days.
Hope that helps make sense of it all, although probably not what you were hoping to hear.
Thank you for responding. I did just figure that out...I need to read properly. ...I was under the impression (not sure how/why) that tesla/my car kept historical data...and this simply retrieved it. In actuality, It's exactly as you state..
Mainly I was just curious to see how my car started started life...its first few steps if you will. When I first picked it up...I was told the car would have 15 miles on it, but I saw 23...where did my car go for 8 miles? Also how did it get 15 to start with? ...just driving around the factory and loading dock? Really? ..just curious...that's all.
