ET Water Announces HermitCrab(R) Compatibility With Weathermatic Controllers

March 16, 2012 - Novato, CA

ET Water Systems, Inc., the leading innovator in smart irrigation management solutions, today announced a new release of HermitCrab®, the revolutionary retrofit product that converts most brands of conventional irrigation controllers into powerful ET Water smart controllers. HermitCrab® now supports all Weathermatic controllers from the ProLine and SmartLine® families.

With a typical installation time of 10 minutes or less, HermitCrab® plugs into a legacy "host" controller via its remote control access port, then connects wirelessly to ET Water web servers to obtain customized daily watering schedules based on current local weather data, site information, and advanced horticulture algorithms. The weather-adjusted schedule is then communicated to and through the host controller, opening and closing valves to provide the exact amount of water needed to keep landscapes beautiful while conserving water and money.

"We found that for many, upgrading an existing site from legacy controllers to smart controllers was cost-prohibitive," said Pat McIntyre, ET Water Systems CEO. "To address this problem, we created a retrofit solution that converts existing legacy controllers into powerful ET Water smart controllers for a small fraction of the cost of new installation. Not only that, but the typical HermitCrab® installation time is 10 minutes, so customers can start saving money, water, and labor right away -- often enjoying payback within one year of installation."

HermitCrab® features and benefits include:

  • Plug-and-Play installation
  • Self-adjusting, weather-based irrigation scheduling
  • Capacity of 48 stations, or the maximum of the conventional "host" controller
  • Reliable and personal customer support from ET Water
  • Two-way wireless communication for site data and sending alerts
  • Remote management of multiple controllers across multiple sites
  • Standard connection for rain sensor
  • Made in the USA
  • Three-year limited warranty

With this announcement, HermitCrab® expands its reach to Weathermatic controllers in the ProLine and SmartLine® families, and remains compatible with conventional controllers from Hunter®, Irritrol®, Rain Bird®, Rain Master®, and Superior/Sterling™. In addition, HermitCrab® can be used with the ET Water QuickDraw service, allowing users to instantly turn irrigation systems and valves on and off from any Smartphone or tablet.

The new release of HermitCrab® is available now. For pricing and further information please visit or call 800-438-3400.
