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-SMT does the rest. Your installation time is cut dramatically. Your irrigation system waters only when the landscape requires it. And you save 30-70% in water.

The proven accuracy of weather-based scheduling

Rain Bird pioneered weather-based control systems for golf courses over 25 years ago. Drawing on the industry-leading precision of these larger, more sophisticated systems, the ESP-SMT makes Rain Bird weather-based control simple and affordable for homeowners like you. By self-adjusting to the landscape’s changing water needs, it eliminates the programming errors and guesswork of a time-based system.

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-SMT 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.

Zone-specific water calculations

Different plants have different watering requirements. That’s why the ESP-SMT 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-SMT controller optimizes the irrigation schedule to promote lush, healthy plant material in each part of your yard, while substantially reducing water waste and runoff.

Expandable modular design

The Rain Bird ESP-SMT can grow with your landscape, easily expanding from 4 stations up to 13 stations with the addition of optional hot-swappable expansion modules.
