Not sure if this dream is too big to be a feature, anyway:
What if you could setup a smart climate control in just a few clicks controlling ventilation, heating (heat pump / gas), boiler, airco, shades. Taking into account my comfort levels, outdoor climate, presence, local energy production and, energy prices. Using a model which calculates your houses thermal isolation and buffer capacity, and the efficiency of my HVAC systems.
Feel free to add on this idea or show what you already have in place.
Now, I have to adjust my heat pump en heat-exchange ventilation schema based on my interpretation of the current and upcoming outdoor climate, and the presence of solar energy production.
I want to optimize for self-consumption of solar energy and minimise the Co2 footprint, within my comfort levels. AI could be helpful technology in this case although I have zero idea how to implement this. I think it could be a game changer for Home Assistant.
That is a bit unrealistic for HA to implement as a general feature.
You can yourself make it for your home, but a general feature would have to deal with each setup of those factors you mention.
Some of the factors will have more or less sensors and service call options and even if they had the same all of them, then each manufacturer will have it own characteristic build that needs to taken into account in the algorithm.
Some will not even have all those factors and other will have even more, like humidifiers/dehumidifiers, air freshners, incense burners and so on.
AI might be able to solve it, but it would have to be an AI that was connected to your home at all times, since as mentioned above no general solution will be available.
That AI is not something HA would be able to run, so it would be a thirdparty that would have to provide it and that would not be free, so it would not be probably not be from the HA team you would se it.
If those AI features were provided by some thirdparty firm, then someone might be making an integration or addon, but I do not see that AI feature yet.
