Modbus steering

I’m evaluating the EVC300400300 for dynamic power management, i don’t have GX devices just the EVC, i can reduce power and boost it depending on availlable power, i can also stop and start charging.
Is it possible to display “waiting for power” or something simular to pause charging instead of stopping and starting?
And another question i have or seeking for suggestions on how to deal with cars that refuse to charge if power returns.
My peugeot doesn’t like chargers that stop power temporarily….
