Ok I don't want to set a depart time so that my car air conditioner will come on and be cool before I leave. I just want to set it if possible to start charging like at 5 AM in the morning when it's not so hot instead of having it start charging the minute I plug it in. Is that possible. Don't really want to use an external timer to start charging.re-reading sounds like if you set charge and depart for 7 am the car will be cooled or heated. Not what I want.
