A smart sprinkler controller is similar to a smart thermostat for your garden or yard in that it automatically adjusts your watering schedule so you don’t have to. A smart controller optimizes your in-ground irrigation system by automatically reacting to weather conditions, allowing you to maintain a healthy landscape while conserving water. We continue to recommend the Rachio 3 for most individuals after four seasons of testing more than a dozen versions. It is the most precise at adjusting to real-time weather conditions and interfaces with the most smart devices while being simple to use.
