Vehicle to house would require power gateway as well. For F150 thats a $3,895 setup according to insideev article Ford F-150 Lightning Home Integration System To Cost $3,895The big problem is safety for the repair crews. Powerwalls and generators have systems that automatically shut off power going to the grid when there is a power outage. Vehicle to house does not. Of course, you can shut the main panel breaker off manually but that requires the human to remember to do that.
What I would find interesting, if a powerwall customer that uses a Tesla home charger could add power from the car back to the home as an extended power source without any costly extra hardware to install. i.e. I have 3 powerwalls with about 40kWh of power, but in the winter when the heat pump / ac of the house sucks it dry in less than a night, this could get me another 24 hours worth of juice from the car. Especially in a 3 car family where you dont absolutely have to drive all 3 cars at the same time.
