If you have a go-e Smart meter than everything works out of the box and you don’t need to do anything. If you don’t have it I doubt that the charger is never taking energy from the net. Even the support mentioned that this will not work. In any case if you are happy with your solution do don’t need the blueprints. They are designed around my need around charging (minimum charge in the morning, charging only PV Surplus, Having a calendar integration that defines when the car needs to be full because i am going on a trip, …).
