And I arrive home to my second surprise.  A quote on the charger I was angling for:

ControlMod - J1772, 70A, ZIGBEE, and data logging

But the hardware alone is more than my original Aeorvironment quote! :'-(

At this point I resign myself to 110V charging, and decide to wait it out on the ChargePoint/Coulomb DoE grant because even though that will be a 30A charger, it will come with all the data logging and I'll only have to pay for install.
