ESP SMART Controllers let you water only when you need to $aving water, time, & money

If you are concerned about water conservation, this is the controller for your home.

RainBird    ESP-SMTE Series

Smart Irrigation Control System

Other Smart Sprinkler Timers claim simplicity and precision; the Rain Bird® ESP-SMTe Smart Control System delivers. Combining the proven simplicity of the Extra Simple Programming (ESP) controller family with the accuracy of weather-based control, this innovative system can now expand up to 22 zones.
Engineered to save valuable time, money and water.

The ease and speed with which you can program this controller is remarkable. Simply input a few key specifics, such as your zip code, allowed watering days and the plant/soil type for each zone; the ESP-SMTe does the rest. Your irrigation system waters only when the landscape requires it. And you save 30-70% in water.

The ESP-SMTe maximizes water efficiency by factoring in everything from soil type to the slope of your lawn to the amount of sun exposure different areas receive. All of these details are calculated for every zone of your automatic sprinkler system to help you maintain a lush, healthy lawn and landscape.

Instant rainfall shut-off and useable measurement

A smart controller should be smart enough to account for rainfall, right? Not always. In fact, most smart controllers simply suspend irrigation when it rains, without accurately measuring rainfall. By comparison, the ESP-SMTe not only suspends irrigation, it measures instantaneous rainfall amounts, determines the effective rainfall and calculates exactly how much to adjust your watering schedule to prevent over-watering and under-watering.

The proven accuracy of weather-based scheduling

In designing the ESP-SMTe, we’ve simply reduced the cost and complexity of the weather-based control systems we began pioneering for golf courses over 25 years ago. Drawing on the industry-leading precision of these larger, more sophisticated units, the ESP-SMTe makes Rain Bird weather-based control affordable for homeowners—once and for all.

Expandable modular design

The Rain Bird ESP-SMTe can grow with your landscape, easily expanding from 4 stations up to 22 stations with the addition of optional hot-swappable expansion modules.

Zone-specific water calculations

Different plants have different watering requirements. That’s why the ESP-SMTe customizes each zone’s irrigation schedule. It factors in location, soil type, landscape slope, plant type/density, sun exposure, sprinkler type and root-depth requirements. Based on this zone-specific data, the ESP-SMTe controller optimizes the irrigation schedule to promote lush, healthy plant material in each part of your yard, while substantially reducing water waste and runoff.
