What is Rain Bird ESP4ME3 Sprinkler Controller?

Rain Bird ESP4ME3 is one of the most flexible smart irrigation controller solutions that supports flow monitoring, with 4 to 22 stations, providing the station count options customers need on residential and light commercial sites. You can upgrade the ESP-ME3 to a Smart controller by adding the LNK WiFi module and a WR2 rain sensor to make programming and monitoring easy through the enhanced Rain Bird app. For water monitoring consumption and protection from a broken irrigation system install a flow sensor.

Design and Features

  • Smart Control: By simply plugging in a Rain Bird LNK WiFi Module, you can access, operate and monitor the irrigation system from anywhere at any time.
  • Weather Monitoring: Internet-based weather information to make daily adjustments to the irrigation schedule, saving up to 30% in water.
  • Indoor/Outdoor Usage: Comes with power plug and outdoor cabinet for indoor and outdoor flexible installation.
  • Memory Storage: Non-volatile storage memory to save your current programming.
  • Emergency Usage: 10-year life lithium battery saves controller time and date during power outages
  • Flow Monitoring: Use with wired flow sensor to monitor flows, get notifications and prevent water waste from broken pipes and leaks.
  • Easy to Read Screen: Large 3” back-lit screen makes the color-coded dial positions easy to explain and understand.
  • Bypass Rain Sensor: Bypass the rain sensor for stations under an eave or deck or in a greenhouse for consistent watering. Automatically prevent watering when it rains.
  • Seasonal Adjust: Save water by changing the seasonal adjustment from 5% to 200% for corrected run times without changing the scheduled times.
  • Alarm Notifications: Be alerted of system issues including electrical, programming, or high flow through a red LED and scrolling messages coupled with mobile device alerts.
