Rain Bird ESP-ME3 Modular Controller

The Rain Bird ESP-ME3 (ESP4ME3EUR) is a modular irrigation controller for 230 V networks, designed to grow with your garden. It ships with a 4-station base module and offers three expansion slots that accept ESPSM3 (3 stations) or ESPSM6 (6 stations) modules, reaching up to 22 stations in total. Expansion modules can be added without powering the controller down. You get 4 independent programs with 6 start times each (24 in total), run times from 1 minute to 6 hours, and flexible scheduling by days of the week, odd/even days or a cycle of 1 to 30 days. A rain sensor input and a master valve output are built in, and the controller is compatible with the optional LNK2 WiFi module (sold separately) for remote control from your smartphone. Non-volatile memory keeps your programs safe during power cuts. A robust, scalable choice for villas, large gardens and light commercial installations.
