Smart irrigation controllers leverage the latest technology to ensure your landscape receives the precise amount of water based on a number of factors including plant material, soil type, slope, sprinkler type, temperature, humidity and rainfall.

We believe the most accurate smart controllers combine on-site weather data with site information to calculate watering times based on evapotranspiration or ET, the sum of evaporation and plant transpiration. Evaporation accounts for the movement of water to the air from sources such as the soil, canopy interception, and waterbodies. Transpiration accounts for the movement of water within a plant and the subsequent loss of water as vapor through stomata in its leaves.

Sounds simple enough, right? Fortunately, the smart people at Weathermatic, the leaders in smart irrigation technology have made it easy with the SmartLine irrigation controller.  We input your zip code, plant type, soil type and slope then it combines that data with the on-site weather station to calculate your precise watering time per zone. With over 200,000 SmartLink units installed around the world, the SmartLine has proven to reduce irrigation water usage by 20% to 50%.

Tired of adjusting your controller throughout the year and guessing how much you need each month?  Now you can let SmartLine handle the adjustments for you based on the on-site weather station and calculated needs of your plant and soil type.  Essentially, this sprinkler controller automatically adjusts itself every day – 365 days per year.
