Use excess Solar to run your pool pump (Node-Red & Home Assistant)
(blog.grieve.com.au)
Discussion about general home automation ideas and projects, home automation protocols like Z-wave, Zigbee, Matter, etc, and home automation software and hubs like HomeSeer, Home Assistant, OpenHAB, Homey.
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:
