I did something like this. I buy my electricity at wholesale prices, and the supplier has an API with price predictions, so I used node-red to compare insolation forecasts, and price forecasts to work out what time-blocks to run the pool pump (when solar high, or price low, or cheapest forecast times to achieve a minimum number of hours per day).
Not quite the same as home automation, but there's a home-made renewable energy system community too:

Are you using Amber Electric? Would you be willing to share your Node-Red flows? I’m trying to come up with some automation for the car charger based on price predictions but it’s been doing my head in…
Sure, I’ll share them today.
Do you have a solar system?
Not yet. The plan is to get solar and battery but the installers I’ve spoken to have been somewhat unhelpful. For now we’re just on the wholesale pricing.
Lemmy.world seems to be groaning under the load of new users. Did you get my DM with the first flow? It never confirmed that it sent.
No DM yet! In fact I can only see this comment in my Inbox, not in the main discussion thread. Teething trouble!
