Modular Exterior Smart Controller plus weather sensor, automatically adjusts watering times for each zone based on temperature, effective rainfall and plant/soil type to reduce water use by 30-70%. Expands up to 13 stations with plug-in module. (Modules sold separately)
Instant rainfall shut-off and useable measurement
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.
The proven accuracy of weather-based scheduling
By self-adjusting to the landscape's changing water needs, The ESP-SMT eliminates the programming errors and guesswork of a time-based system.
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.
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.
