Time depending heating activity and temperature hysteresis

Is your feature request related to a problem? Please describe. No, it is a feature request.

Describe the solution you'd like Currently, evcc is heating up to the desired temperature when there is energy available or when the temperature is below the minimum. That means, that for example the heating is started in the morning although the warm water is needed in the afternoon.

I would like to have something like a schedule with times and temperatures that can be defined:

• 8 am to 2 pm: keep temp at 40 °C
• after 2 pm: heat up to 50 °C

And, additionally, include a hysteresis, if possible.

Describe alternatives you've considered Alternative would be to include Home Assistant to release the heating and adjust the temperatures.

Additional context Add any other context or screenshots about the feature request here.
