Load Powerwall

[MyLive]

Hi everyone :-),

is there a API Call to tell the Powerwall to Start Loading / Stop Loading ?
I Like to use a dynamic Electricity tariff ... when the Price is very Low, i like to Load the Powerwall and if the Price get higher, stop Loading the Powerwall if not enougth "Solar" Power aviable.

Thanks a lot and have a great Day,
René
