Please note that over a month later I am still suffering fromthis problem. Every single night wothout fail, I must manually change the charge setting from 23:30 to 00:30 or else i get charged for chargingthe battery one hour early during expensive time.
I stumbled on this as proof that it is Wonderwatt sending the command.

and the same the xext day, and every day.....

I think its becuse I was on intelligent go at one time (I moved to just go later as they were charging my car out of hours and charging premium for it). But the start at 23:30 is constant and every day even though I have it turned off in my account.
Can you remove intelligent go as its no longer needed and causing this constant problem.
