What makes you think Teslafi prevents your car from sleeping, it doesn't mine.Don't use Teslfi or any apps that prevent the car from sleeping. They drain the battery and are pretty pointless.
If you read the other range threads, they'll say the cars rated range is only applicable when unplugging and driving the 2XX miles to your destination in the right conditions.
You've said it yourself, short journeys. The car uses power to heat and cool the cabin and pack. It's cold. I'm guessing your wh/m is closer to 320 than it is to 240.
Combine these and that's why your range is low than "rated".
Maybe you should look at Teslafi settings or avoid using the app to check on the car.
