Rain Bird ESP-ME3 4-Station WiFi Irrigation Controller | Indoor/Outdoor ESP-ME3-A1

Flexible irrigation control for homes and light commercial sites

The Rain Bird ESP-ME3 4-Station WiFi Ready Controller delivers dependable, scalable irrigation management for lawns, gardens, and small commercial landscapes. It ships with four zones and can be expanded to twenty-two zones with optional modules, letting you tailor coverage as your landscape evolves.

Smart scheduling that adapts to your site

When paired with the optional Rain Bird LNK WiFi Module, the ESP-ME3 becomes a connected controller. You can access, operate, and monitor irrigation from anywhere, and internet-based weather data is used to fine-tune daily schedules, helping manage water use more efficiently.

• Four zones included at purchase, expandable to up to twenty-two zones
• Non-volatile memory preserves settings through power outages
• WiFi connectivity enables remote control and monitoring via the Rain Bird app
• Flow monitoring compatibility with wired sensors provides real-time alerts and protection

Upgrade and protect your landscape

For a more advanced setup, upgrade the ESP-ME3 to a SMART controller by adding the LNK WiFi Module and WR2 rain sensor. This pairing supports automatic adjustments and enhanced weather-based scheduling, and it can lead to EPA WaterSense certification when combined as directed.

Real-world benefits and use cases

Ideal for lush residential lawns, mixed planting beds, and modest commercial entryways, the ESP-ME3 adapts as your landscape grows. The architecture supports future expansion without replacing the core controller, helping you plan ahead with confidence.
