Allow configuring charge speed per hour of the day.

Is your feature request related to a problem? Please describe.
I live in a place where we have fixed energy tariffs depending on how much power is being used each hour. Because of this I have already incorporated smart control of my water heater, so I'm calculating which hours of the day to run my water heater based on the electricity price, same as this integration.

This however, poses an interesting issue when using this integration. I'm controlling the speed of the EV charging based on the power draw of the house, and while the water heater is running, the speed of the EV charger will automatically be reduced to make sure I stay below the fixed tariff level I want. This means that the charging speed of my EV is not linear. And since I'm only able to input a single number as the charging speed with this integration, its hard to know which number to input, since the speed might be lower if the calculated hours for the water heater correspond with the EV charging hours.

Describe the solution you'd like
I would like to be able to set the EV charging speed individually per hour of the day. Lets say I calculate in advance that the water heater should run between 2am and 4am in the night, during that time I would like to set the charging speed lower, and in other hours it can be set higher since I know the water heater won't be running then. With such a solution, this plugin could take the lower-speed hours into consideration when calculating which hours to charge the EV.

I'm not entirely sure of the cleanest way of implementing this with HA-entities. 24 inputs for each hour of the day seems excessive, so I'm open to input on how to solve this as clean as possible.

I understand your situation, but this kind of improvement will make the integration much more complex. It is also related to similar tariffs schemes were your monthly fee depends on how the maximum power per hour that you consume. Not sure when or if this integration will be able to support these more complicated cases. But if it will, my thinking has been to switch from "% per hour" in charging speed to "kW", in order to make more advance functions. After such a change, it might be possible to also do what you describe.
