Rain Bird ESP-SMT4 Smart Irrigation Control System Features and Benefits

  • The proven accuracy of weather-based scheduling
    By self-adjusting to the landscape's changing water needs, it eliminates the programming erroESP-SMT's tipping rain bucketrs and guesswork of a time-based system.

  • 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.

  • Zone-specific water calculations
    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, wInside the ESP-SMT's Modular Designhile 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. Compatible module: ESP-SM3 3 station expansion module
