I suspect you would have to open up the EVSE (or cut the wire to the
J1772 plug) to get access to the pilot line, but the advantage is that
it uses the EVSE's built in contactor to switch the high current power,
so you don't need to buy an expensive big relay to switch power on/off
to the EVSE itself.

If this is for the J1772 EVSE, it has a low-current "pilot" signal that can
enable or disable charging. The details are described here: [...]
That's another interesting possibility. I wonder if any of the existing EVSE
units have implemented an interface to this already, perhaps as an add-on?
Thanks for the tip, Lee.
