HiOn our Tesla battery app it shows under Powerwall 'Grid Services' and currently as an example we are sending 2.5kw to powerwall but also 2.9kw from the grid to our powerwall. Total power to powerwall 5.4 kw. However under grid services it says we are providing power to the grid. The app does not read that way, why are we paying for power from the grid when our battery has plenty of charge. Regards, Wayne
