[Ovmsdev] Anyone working on Ioniq 5?

[Michael Geddes]

Thanks very much Mark, that was very helpful.

OVMS Module ordered, with hopefully all the right cables :) and the dev kit
downloaded and compile environment set up.

Getting hold of service manuals might be a stretch, but I guess I'll reach
out to a couple of people and see how we go!
