Pool pump controllers are RIPE for disruption. They are high priced, of poor quality, and expensive to operate. Pool pumps, poorly run, are a significant waste of money, consume massive amounts of electricity, generating pollution and greenhouse gases.
Rachio has revolutionized a sprinkler market sharing a similar story.
In my imagination there would be a web connected controller, maybe with a temp probe and flow meter to dynamically run a pump more when hot, less when cooler, none below 60F until constantly below 35F. It would also do variable speed control or run times to optimize flow rates, minimizing cost. It could send alerts if there are flow control problems, suggesting filter backlogs or general flow problems. This could generate significant customer value, disrupting another staid industry.
I would be happy to answer any questions if you are interested.
