Controller Link

Controller Link is a simple upgrade for existing sprinkler timers to provide climate controlled irrigation.
Controller Link saves water by managing irrigation, based on real-time weather conditions.


What We Do


Success Stories
ET = Evapotranspiration

Evapotranspiration (ET) is the amount of water that evaporates from the soil and transpires from plant leaves.  To keep plants healthy, moisture lost to evaporation should be replaced by rain or irrigation.

Climate Conditions

On hot, dry windy days plants need more water.  On cool, cloudy days plants rarely need to be watered.  Climate conditions cause water to evaporate from the landscape. 

Proven Science

The internationally accepted ASCE Standardized Reference Evapotranspiration Equation is used in Weather Reach Water Management products.  ET science has been used, refined and trusted for over 40 years.  Weather Reach brings this science to your landscape so you can enjoy the benefits of climate controlled irrigation.

Smart Irrigation Depends on Sensors

Weather Reach uses hourly sensor measurement from precision instruments to automate irrigation control.  ET Weather stations are properly sited and well maintained to make hourly measurements of four climate conditions:

  • Solar radiation or solar energy is the primary energy source driving both evaporation and transpiration from plants.  It is the most important measurement needed to accurately calculate ET.  A Pyranometer is a precision sensor that measures solar radiation.
  • Wind accelerates evaporation.  Increased air movement increased evaporation, particularly when the air is very dry.  Water evaporates faster on a hot dry windy day.
  • Humidity, the amount of moisture in the air, affects the rate of evaporation.  Evaporation slows when humidity is high.  This can be seen when clothes are put outside to dry, it takes a long time for them to dry on a muggy day.
  • Temperature also affects evaporation; as it gets hotter plants dry out.  Temperature measurements must be coupled with wind and humidity measurements to measure evaporation.
Beautiful Landscapes Sustained by Efficient Irrigation Weather Reach is built on the concept of using high-quality weather stations that are well maintained, to provide hourly weather conditions to smart irrigation control.  Our # 1 priority is beautiful landscapes.  Efficient smart water management saves money, conserves water and sustains beautiful healthy landscapes.

One weather station ….. thousands of landscapes.
