We only sell these three smart controllers because we want to make things easier on homeowners. Why choose from 20, or 100, when these three will cover nearly every homeowner's needs?
All of these controllers are often eligible for rebates from water districts, but the Hunter Pro-C and Weathermatic SmartLine require you upgrade it to include a weather station (you can order it this way from us). This is because the rebates are granted for Smart Controllers—which means they get weather data and automagically adjust the watering schedule.
Our Favorite is the Rain Bird ESP-SMTe because it takes into account MANY aspects of water use. It requires more futzing to get it set up, but in the long run, it's the closest thing to set-it-and-forget-it you're going to find.
