Ok, thanks.
So it is all coming from the charger. No car messages.
Can you post a message that is used while the car is charging and explain what part does/means what?
(How much power has gone into the car, is the car charged?)
I appreciate you are doing a bit of extra stuff with your solar panels, etc.
But for this example we will try to concentrate on the message ONLY for the car.
2 seconds is fine for how often.
