Features & Benefits of the Rain Bird ESP-ME3 4 Station Controller

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.

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.
