Grid first charging schedule

Hello. I’m trying to configure CHQ app to create a grid first charging schedule. This is using a solar system with a Powerwall battery, a Wallbox charger to a VW idBuzz. I’ve followed instructions to do so but the CHQ app still pulls power out of my Powerwall and not the grid. I really don’t want to burn thru my Powerwall charging my car overnight. Any suggestions besides getting a Tesla car? :laughing:.

TIA
Mark

“is is there a way to configure the charge HQ app so that it charges my non Tesla ev from the grid before it pulls electricity from my battery”
