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.
