Feature Request: Switch between alternative heat sources depending on solar production

[Kugelfang666]

What is the feature?

Choose between the heat source in a smart way to optimize costs depending on boundary conditions.

Description

I live in a house which is equipped with:

• traditional heating (radiators with Tado valves)
• split air conditioner units in every room
• a solar installation generating electricity

I would like to optimize my costs for heating by utilizing the air conditioner to warm up my house during times where its not too cold outside and my solar installation generates sufficient surplus of electricity.

When the solar production goes down or the outside temperature is lower than a defined threshold value better thermostat should switch over from setting the temperatures on the aircon units to use the traditional heaters again

Additional Information

All devices are connected to Home Assistant so I do have sensors which indicate the solar production, solar forecast, apparent temperatures....
