Considering a Smart Controller
Written by Doug Chilton, Sales Representative
In Southern California as well as throughout the state, the cost of water is increasing at a dramatic and accelerated rate. In today’s challenging economy this is no small matter. People are looking for ways to save on their energy and water costs in their homes.
Homeowners are turning to smart controllers for a way to save significant amounts of water and money. Studies show most smart controllers will save up to 25% of the water applied by that of a traditional controller. The following will give you some information on the various smart controllers in the market that you should consider when making your choice.
What makes my controller unintelligent?
I’m sorry to say it, but we do. Ordinary or unintelligent controllers rely on us, the user, to set the timer that operates the irrigation. We determine the amount of days and length of run times for a particular valve to irrigate. Most of those times are wrong. We water every station the same amount. We don’t set it to stop watering when it begins to run off onto the street. We don’t make any changes to the schedule until after the first rain. How many times has your controller watered during a rain storm?
What makes a controller smart?
A smart controller automatically adjusts the irrigation schedule in response to changing weather conditions. Another name for a smart controller is weather-based. They use information about local environmental conditions, like temperature, humidity, rain, plant and soil types, to determine and calculate how much water the landscape needs to stay health. They automatically lower the run times as the season cools and we head into winter. They will shut off during a rain storm and have rain soak delays before resuming standard programming.
Smart controllers can collect weather data in 3 different ways: an on-site weather station, receive weather data through Wi-Fi or through cellular connections. They can be operated by a smart phone or through the Internet. They can read flow and report any unscheduled or overwatering.

The controllers still require to be set up effectively. Some technical knowledge in setting up the controller’s performance parameters is required. Additional tweaking of schedules and input data is needed to fine tune the controller’s performance. It’s not a “set-it and forget-it” device. An irrigation system with a high degree of uniformity in applying water is paramount to helping save water. If you’re watering your sidewalks or street, a smart controller will help you do it more efficiently.
