Weather-based Smart Modular Control System

4 to 22 Station Indoor or Outdoor Smart Modular Control System for Residential and Light Commercial Use

Now with both Simple Smart Programming and Advanced ET watering features, the Rain Bird® ESP-SMTe smart control system combines the proven simplicity of the Extra Simple Programming (ESP) controller family with the accuracy of weather-based control. To program, simply input a few key details, such as zip code, allowed watering days and the plant/soil type for each zone. Then the ESP-SMTe waters only when the landscape requires it and your customers save an estimated 30% + in water.

Instant rainfall shut-off and usable 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.

Programming Recommendation

Rain Bird recommends that the maximum irrigation zone cycle time be less than the time required for runoff to begin and that there be adequate soak time before the next irrigation cycle of that same zone begins again.
