Large kWh Loss while Sleeping-Seems Very Strange

Last night, TeslaFi reported 6 hours sleep time for my new Model Y. It also showed nearly 1 kWh loss, a huge amount relative to kWh losses during other sleep sessions where loss is minimal. For instance, the night before, car slept nearly 14 hours and only lost .1 kWh. Something isn't right.  Any thoughts?  Thank you.
