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.

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 Rachio and Hunter websites contain various installation guidance and training videos for the controllers that were available at the expo.
