Smart Irrigation, Perfect Landscape

WeatherTRAK ET Pro3® is the hands-down most tested and proven commercial-grade smart irrigation controller on the market today. This proven controller is EPA WaterSense certified and passed the Irrigation Association’s Smart Water Application Technologies (SWAT) protocol with a perfect score. The ET Pro3 can control a single site or an entire portfolio of sites using conventional wire technology or advanced 2-wire technology.

The WeatherTRAK ET Pro3 smart irrigation controller uses ET Everywhere®, the most precise, high-resolution weather data available, to create specific schedules

Features

With its proven ability to tune irrigation to your unique landscape and site characteristics, the WeatherTRAK ET Pro3 controller reduces water waste by only irrigating when it is necessary – saving you time, resources, and money.
