ESP-ME3 Modular Residential Controller
The ESP-ME3 modular controller is Rain Bird’s most flexible residential controller. It expands from 4 to 22 stations with 3 or 6 station modules and can be installed indoors or outdoors because it comes with a pre-installed power plug. The ESP-ME3 controller can be upgraded to a SMART controller with EPA WaterSense certification by adding the LNK WiFi module and a WR2 rain sensor. A flow sensor can also be added for water monitoring and protection from a broken irrigation system.
