I have a 15 amp power outlet which is on a controlled load circuit (also known as J tariff), the circuit is used mainly for Hot Water systems, but in certain states you can also use for EV charging (and yes in SA it can be 15 amp powerpoint). It comes on somewhere between 11pm and 12:30, and runs for at least 7 hours. My i-MiEV charged fine using this circuit. I would just get home and plug it in, and it would charge overnight. As I do not have my Tesla HWPC charger installed, I have been using the 230v 15 Amp Tesla charger to charge my Model 3. But it seems if I plug in when I get home, the Model 3 goes to sleep before the power comes on. I have tried both Sentry on at home to keep it awake, and setting the Model 3 to start charging at 1am. But it seems it does not wake at 1am if there was no power at plug in. Whether it will start charging depends on the time of when I plug in, and when I last look at the car in the app. Has anyone worked out how long the car stays awake after plug in or app usage? Will I have the same problem with the HWPC?
