The Rain Bird ESP-ME3 is the industry’s most flexible residential and light commercial irrigation controller, designed to grow with your landscape. Starting with 4 stations, it can be expanded up to 22 stations with 3- or 6-station modules—without removing or powering down the unit. This modular design allows contractors and homeowners to easily add zones as landscapes expand.

With Rain Bird’s Extra Simple Programming (ESP) interface, the ESP-ME3 offers intuitive navigation via a large backlit LCD display and simplified dial programming. Four individual programs with six start times each provide exceptional flexibility for any irrigation schedule. Built-in Contractor Default™ settings, advanced diagnostics, and rain sensor bypass options make programming and troubleshooting fast and professional.

When paired with the LNK2 WiFi Module and a WR2 rain sensor, the ESP-ME3 becomes a SMART WaterSense®-certified controller that adjusts watering schedules based on real-time weather conditions—saving up to 30% in water use. For even greater protection, it supports flow sensor integration, detecting breaks, leaks, or blockages before they cause costly damage
