The "Smart" outlet uses as much power as the EVSE does when idle, utterly pointless to have a smart outlet
Sorry to bust your bubble, but the tar load of the smart outlet ( it has a power supply, computer an circuits always powered ) is typically the same 1-2 watts, meaning you save nothing.There is a 2W draw when the car is done charging. I set the smartplug to turn off after charging to prevent the extra draw.
