So I set mine up and then checked my Sense (whole home power meter) and confirmed the car charged last night at 8kW. So mine is working.
What I mean is I pull into the garage, and pull up the charging screen in the car. It says 48/48 amps at 1am at this location. Then I get out of the car, plug in the wall connector, and the screen now says 32/48 amps at 1am.
If I charge it immediately or let it start at the delay, it charges at the correct amps.
I have also verified that I can change the amperage at any time while charging.... except I have not yet tested that in the middle of the night.
