I have a 12v compressor fridge. It's great, only draws about 30-40 watts 1/3rd of the time, cycling on and off. The problem is that when the car goes to sleep, the 12v port goes off. It is debatable if wiring an always-on 12v port is good for the 12v battery and it requires hardware mods. Problem is, if you turn off sleep to keep the 12v port on, by using sentry mode or similar, it eats 250w to run a 15w average fridge! You lose 16 to 20km per night, not 2.
One possible solution, easy for Teslafi and very useful to customers is to be able to tell Teslafi, "keep the car awake for 1/3rd of the minutes in every hour when it's parked." One could tune the duty cycle manually, or even adjust it based on interior temperature. (Ideally if one could read the current on the 12v port you could just wake up long enough for one fridge cycle, then sleep for a while, then wake up for another.)
But more simply, just stop the car from sleeping (the lowest power way there is, turning on sentry works but there might be something better.) If it's been sleeping longer than 20 minutes, turn it on for 10, all night. Yes, you would get vampire drain but 1/3rd of what leaving sentry or camp mode, or summon standby on all the time. It would not work with no data connection (perhaps a mobile app could) but it would be a great start?
And could I get it tomorrow? (I might be able with the scheduled actions by hand but I am on vacation.) :-)
