I did some searching and browsing in the forums and I don't see that anyone's asked this already... I know that the Tesla UMC and the HPWC connectors can pop open the charge port door with the press of the button. I was wondering why Tesla didn't put a similar button on the J1772 adapter, and since they didn't, is there a way to figure out how to get one on there? I'm not sure how it's talking to the car -- does anyone know? Is it simply a magnetic pulse or something like that? I'm going to have a HPWC in the garage, but a J1772 at work, so I'd love to be able to figure out a way to put a button on the adapter... Any brave soul taken apart the UMC yet?
