Rachio Iro Smart Sprinkler Controller

Rachio, maker of the Iro Smart Sprinkler Controller, announced availability of version 1.7 of the Rachio App with enhanced evapotranspiration (ET) technology. The update should lower Iro users’ water usage for residential irrigation by as much as 30 percent. ET rain delay monitors the true soil moisture loss between previous and scheduled waterings and automatically skips the irrigation schedule when sufficient water is present. ET-based seasonal adjustments monitor actual evaporation loss on a weekly basis and apply a percent change adjustment, increasing the amount of water used as days get longer and/or warmer, and decreasing the amount of water used as days get shorter and/or cooler. The app upgrade also includes new vegetation, soil, exposure (shade), nozzle, and slope options; creating 168 unique cycle/soak settings. The additional data points significantly reduce runoff and increase schedule optimization. Other key updates include the ability to create custom nozzle types with unique flow rates.
