Thanks! I do however hope that all I need is the documentation at the link below. My main problem was how to communicate with the ELM327 chip, which is not a problem now. I will try to make a small python program for interpreting all the data and run it on a pico so I can easily sent it using MQTT fro mwhere my EVSE control will pick up, and optimally charge my Leaf depending on temperature, price, SoC, etc.
