My current setup is a pi 4 with a big usb ssd plugged into a usb power bank which is itselfpowered from 12v. Only thing “integrated” is I run marcone/teslausb. The power draw is inconsequential compared to powering the mcu & sentry, and I have never worried about it. My first 12v battery lasted a pretty normal 5 years. I have heard other folks have canbus interfaces or run apps that can be accessed via the in-car browser, but I don’t know much about things in those domains other than sniffing some battery cell data once. If you want to properly tinker with Teslas you have to basically be invited to join Fight Club, so it hasn’t been very appealing to try to get into. The culture is very different, and it doesn’t interest me much.
