What makes it so smart?
"It isn’t just the app, which RainMachine does of
course have. The intelligence comes from the ability to tap into the local
weather forecast and adjust the watering accordingly. This is critical for us
in Southern California in the midst of a severe drought, with watering
restrictions and unreliable rainfall. The controller taps into the National
Oceanic & Atmospheric Administration (NOAA) database for a specific,
location-based forecast that updates regularly to account for changes in
weather."
Surprisingly Easy Installation and Setup
"Setting up a basic program is really simple. Touch the Settings icon, then select Programs, then Add New Program. You can name the program (such as Vegetable Garden or Lawn), then set the frequency of watering (every day or every n number of days), the start time, and the base watering duration. The base watering duration is the amount of time to water on a typical summer day, say, five minutes."
