The industry’s most flexible irrigation controller solution that supports flow monitoring, LNK WiFi, and up to 22 stations.

With 4 to 22 stations, the ESP-ME3 provides the station count options customers need. Install the same controller on residential and light commercial sites. Add station modules when expanding irrigation without removing or even powering down the controller.

Upgrade the ESP-ME3 to a SMART controller by adding the LNK WiFi module and a WR2 rain sensor. The LNK makes programming and monitoring easy through the enhanced Rain Bird app.

For even greater water monitoring and protection from a broken irrigation system install a flow sensor.

Features:

WiFi Connectivity
By simply plugging in a Rain Bird LNK WiFi Module (sold separately), users can access, operate and monitor their irrigation system from anywhere. Internet-based weather information is used to make daily adjustments to the irrigation schedule, saving up to 30% in water.

Flow Monitoring
Compatible with multiple sizes and makes of wired flow sensors for flow monitoring and notifications to save water and protect against property damage.

Flexible Installation
Configurable to 22 stations with additional 3 or 6 station modules for different sized jobs or future irrigation needs. Comes with power plug and outdoor cabinet for indoor or outdoor installation.

Simplified Dial Programming
Large text and symbols make the color-coded dial positions easy to understand and explain.

Easy to Read Screen
Large 3” back-lit screen is clear to read in dark garages or sheds.

Bypass Rain Sensor by Station
Bypass the rain sensor for stations under an eave or deck or in a greenhouse for consistent watering.

Seasonal Adjust by Program
Save water by changing the seasonal adjust from 5% to 200% for corrected run times without changing the scheduled times.

Alarm Notifications
Be alerted of system issues including electrical, programming, or high flow (when using a flow sensor) through a red LED and scrolling messages coupled with mobile device alerts when used with the LNK WiFi Module and the Rain Bird app.

One-Touch Watering
With the dial in the AUTO position, just press and hold the right arrow button to start manually watering the current program.

Contractor Default™
Simply save a default program and if the original watering schedule is overwritten in error, easily restore it in just two steps.

Specs

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.
