    So I woke up this morning to a frigid interior - my AC had been set to "LO," as it seems to perform better this way in the socal heat, but when I entered my garage, I heard the AC running. This isn't the first time it's happened. I use TeslaFi and the Remote-S/Tesla-App, not sure if those are causing it... Since it was overnight, I'm certain that it wasn't the over-temperature protection (whatever happened to Elon's promise of being able to set a lower threshold on that anyway?)

    There is a setting - Settings, Vehicle, Smart Preconditioning. If this is on, the car attempts to learn from your habits and will have the cabin ready for you. For example, if you are always heading to work around 9am, this setting will make it so that it is ready by 9am by turning on the climate control.

    I am glad you asked this question as my Tesla Model S is occasionally doing the same thing in the mornings and I was getting worried. I know when I went to bed the climate was set of but when I entered the garage this morning it was clearly running. I am always afraid this would be running all night and drain my battery.......
