I installed a pedestal and new in the box wall charger next to my car port last week. It works great on my model S with up to 48 amps but I dial it back to 32 unless needed. Here is the rub, When I go to unplug the charge cable after it is done it will not unlock from the charge port by pushing the button. I have to go in my app and tell it to unlatch, I assume I could do this in the car as well, but shouldn't I be able to do it from the Wall Charger handle ??? When I push and hold the button it cycles back on to charge again. Hit it again and I get dark blue but never lite blue to indicate unlatched...
