ESP-ME3 Series Controllers

The industry’s most flexible residential/light commercial irrigation controller 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 with EPA WaterSense certification by adding the LNK WiFi module and a WR2 rain sensor. The LNK makes programming and monitoring easy through the free Rain Bird app.  

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