I'll never get why this happens. The window is midnight to 3pm. Departure time is 9am, and granny charging from this point takes maybe 6 hours.
So why does it start sometimes at 10:30pm? Not consistently, but maybe 1 in 3 times. I was looking into a high-amperage timer, but it looked like I'd be moving soon, so I stopped, hoping I could get an L2 in my new place (landlord denied me adding a 240V outlet). Guess it's time to start looking again. Fresno electric rates are $0.30/KwH during the window, but $0.49 to $0.61 outside it.
