Have you thought about offering the same functionality for commercial irrigation? I have two farms both with electric motors and pivot systems, I want to minimize water usage without sacrifice crop performance. There are systems out there to remotely start & stop systems, but they are expensive and only offer start/stop functionality. forward reverse, and watering amounts. No heat, humidity, weather inputs. Ability to integrate with moisture block up to 1500 feet away is a must.
I think there is a viable opportunity here based on the water I have saved just on my yard.
