Smart irrigation controllers automatically tailor watering schedules and run times on sprinklers or drip systems to meet specific landscape needs. These systems use weather information and/or site conditions to determine how much water to apply and when to run. Once the smart controller is installed and programmed, little additional monitoring is required.

Studies show most smart controllers will save up to 20% of the water applied by a traditional controller. This is a significant water savings because, in the Valley, up to 70% of household water use is outdoors.

Smart irrigation controllers vary in their complexity. Installation requires some basic electrical knowledge and can be accomplished by most homeowners in approximately three hours. If you choose to hire someone to install the controller, please check to make sure they are licensed, insured and bonded.

The Rain Bird ESP-SMTe weather-based irrigation controller has been tested by the Irrigation Association's Smart Water Application Technologies (SWAT) team. This model has Extra Simple Programming (ESP) features to save valuable time, money and water.

The ESP-SMTe collects and measures onsite rainfall amounts. The internal memory contains over 8 years of historical weather data. This data, along with the onsite rainfall and temperature information is used to adjust the watering schedule on a daily basis. The ESP-SMTe Cycle and Soak™ feature allows the controller to adjust run times based on soil conditions and slope to reduce/eliminate water run-off.

Rachio’s Smart Sprinkler Controller is also SWAT-tested by the Irrigation Association. The companion mobile app leverages historical and real-time weather data allowing for easy configuration and control from anywhere in the world.

The Smart Sprinkler Controller leverages a nationwide network of personal and federal weather stations for its Weather Intelligence feature set. Weather Intelligence includes seasonal adjustments, rain skips, and more.

Additionally, the Rain Bird and Rachio controllers have earned the WaterSense label from the Environmental Protection Agency's (EPA) WaterSense partnership program. The label certifies that the controllers have passed the EPA's rigorous testing requirements, confirming the controller's water-efficiency and performance in landscape settings.

The model is a four-station outdoor controller and easily expandable to 22 stations. Expansion modules may be purchased separately.

The model featured at the expo is an eight-station indoor controller that can be outdoor adapted by using an enclosure box.
