Functionality wish: Set limited power output on an active charge

I'll start by saying that I like your product - I'm using primarily your mobile app, but also the home assistante (not affiliated) integration.

I have a feature request for both the mobile app, but more importantly your api.

Please add the option to set a limited power output - the reason for this is to be able to utilize my excess solar power produced. So if, for instance, I have 3kW excess power right now, I would like to be able to limit the power output.
