So charged model y last night. Tesla app
Shows 30kwh added to car charts topped just before cheap tariffs cut off. But in smart meter in house shows 37kwh used. Now apart from dishwasher on overnight and various standby items the discrepancy seems high? Usually use with white goods and standby no more than 2.5 kWh per night of not charging the car- any idea why this is?
