Rain Bird ESP-4ME3-WiFi Ready Indoor/Outdoor Sprinkler Controller-Modular Outdoor Controller, 120 Volt

The Rain Bird ESP-ME3-Indoor/Outdoor WiFi Ready Sprinkler Controller has enhanced programming, making it easier than ever to program your sprinkler system. The ESP ME3 controller supports flow monitoring, LNK WiFi, and now has a higher station count from 4 to 22 stations that can better serve residential to light commercial sprinkler systems.

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 LNK2 WiFi module and a WR2 rain sensor. The LNK2 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.
