How to automate the usages of my home appliance to use my solar excess?

Hi,

I’ve some of my home appliances that I can start within Home Assistant.
I now have solar panel and I would like to start some devices, when their consumption is at least met by the solar panel(and additionally some other conditions like, if my washing machine door is closed, which I also have in home assistant).

Is there some integrated way of doing this? Or with an additional addon? Preferably with a GUI and installable from HACS?

I tought of doing myself some automations, but it’s not that simple because most appliance doesn’t use the same power all the time, so I need to “book” for some power, and make sure that 2 devices are not starting at the same time because both automation saw there was 500w available.

Thank you for your help!
