This is the companion app for Sprinkl Conserve, an add-on to existing irrigation controllers that adds advanced conservation features, the ability to remotely control schedule days, and municipal restriction handling for certain areas. When installed Conserve works as a governing body to an irrigation controller, telling it when and when not it should water, using current and historical weather patterns for its installed location. Conserve works with virtually any low-voltage irrigation system and installs in minutes using the rain sensor circuit or by interrupting the common wire used in irrigation wiring.
