I’m currently in touch with Hyundai / KIA to discuss what official API access could look like. It’s clear that the world of home automation is still quite new to them, and they’re exploring what the best approach would be.
In an ideal scenario (which I’m rooting for) they’ll release officially supported APIs so not only we, but the entire smart home community can benefit.
That said, these are large organizations with many layers to work through, so things might take some time.
