How does a “smart” controller make watering my landscape easier and more convenient?: Traditional sprinkler timers require manual adjustments every time the weather changes. “Smart” controllers automatically adjust the watering schedule based on local weather/site conditions. So, once the initial setup and monitoring is complete, there’s no need to reset the timer. The “smart” controller makes adjustments automatically.

How will installing a “smart” controller save me money?: A “smart” controller saves you money by reducing your water use. Your actual water savings will depend on how you have watered in the past. Pilot studies have shown typical water savings to be in the range of 20%-40% annually.; “Smart” controllers also save money by providing a healthier landscape, since a landscape that is properly watered will be less likely to suffer from fungal disease and insect infestations that can require costly treatments, thereby protecting your landscape investment.

What questions should I ask before purchasing a “smart” controller?: The Irrigation Association®, a non-profit organization supporting water conservation through efficient irrigation, has published an Irrigation Consumer Bill of Rights to educate consumers about the questions to ask their contractor before purchasing a new irrigation system. Be sure to read it prior to meeting with your irrigation professional. And before beginning any work, be sure to confirm that your contractor is specifically trained in the installation of the “smart” controller they have selected.

Where do the automatic adjustments come from?: “Smart” controllers receive the environmental data they need from various sources, depending on the make and model. Some models use data from local weather stations or on-site sensors, while other models gather information from several weather stations linked to match the zip code and address of the installation site. Each type has the capability to work equally well. Look for the type suited to the unique attributes of your home landscape.

How much do “smart” controllers cost?: The cost of “smart” controllers varies according to the number of zones and features included in the controller model you select. Most range in price from a few hundred dollars on up, plus installation.

Which “smart” controller works best?: Different “smart” controllers each have different features and benefits. A certified irrigation contractor can help you make the best choice for your specific needs.

How have these products been tested?: Manufacturers of “smart” controllers rigorously test their products before releasing them for sale.

If I install a “smart” controller, will I get a discount on my water bill?: Less water used for sprinkling means less water delivered through your water meter. When you reduce water use by installing a “smart” controller, your reduced use will result in a “discounted” water bill.
