You are funny - a timer or remote controlled switch is of course doing exactly that, turning the charging pile on when you want to charge.....or are you one of those individuals that wears suspenders and a belt? ????
As for programming the charging pile to work without RFD card, this is how to proceed:
IMPORTANT: on the phone with the MG app running, Bluetooth, location, WiFi and cell services ALL have to be turned on.
go into the charging menu via the 'Charging' icon
Step 1: connect the phone to the charging pile via Bluetooth while the car is connected to the wall-box and charging
Step 2: click on the icon per arrow 2
Step 3: on the new window that opens, select card free
Step 4: a new window pops open, slide the selector to 'on', save, exit
VOILA! no RFD card is required ever again, life is easy, life is good.......no worries anymore!
