ESP-Me Series Controllers

A flexible irrigation controller solution, supporting from 4 - 22 stations and a WiFi upgrade.

With 4- to 22-station scalability, the ESP-Me helps you better serve your customers. Install the same controller on residential and light commercial sites – the more stations you add, the more you save, providing you and your customers with more value for the money. 

Best of all, you can upgrade the ESP-Me by simply installing a LNK™ WiFi Module, without having to replace the entire unit.

Make your controller SMART by adding the EPA WaterSense labeled LNK Wifi module and WR2 rain sensor.
