Arikit Rain Bird-compatible 6-Station Expansion Module for ESP-Me / ESP-SMTe — Hot-Swap, Adds Six Valve Outputs

The Arikit-compatible Rain Bird ESPSM6 is a plug-in 6-station expansion module that instantly increases an ESP-Me or ESP-SMTe controller’s capacity without shutting power off.

Need more zones but want to avoid replacing your whole controller? The ESPSM6 expansion module gives you six additional valve outputs by sliding into an open module slot on Rain Bird ESP-Me and ESP-SMTe series timers. Installation is quick and tool-light: the module is designed for hot-swap insertion so you can expand capacity while your irrigation system remains powered and programmed. Note: this module works only with ESP-Me and ESP-SMTe controllers and is not compatible with older ESP Modular or ESP SMT models.

How does the ESPSM6 expand my existing irrigation system?

The ESPSM6 provides six extra station outputs that integrate into the controller’s program logic, allowing new valves or zones to be scheduled alongside existing ones. Once installed, the controller recognizes the added stations and you can assign them to programs or manual operations via the controller interface.

• Adds six valve outputs per module for more zones without replacing the main controller
• Plugs into any available module slot on ESP-Me or ESP-SMTe controllers
• Supports manual activation and integration with existing scheduling

What is involved in installation and setup?

Installation is designed for homeowners and technicians: slide the ESPSM6 into an open slot on the controller’s module bay and secure it per the controller manual. You do not need to power down the controller, and once the module is seated, wire the new valves to the station terminals and configure their programs on the controller’s keypad and display.

• Hot-swap capable — install without turning off controller power
• Standard wiring to station terminal block for each added valve
• Program new stations using the controller’s existing menu and program structure

Which controllers and systems are compatible with this module?

This expansion module was manufactured for Rain Bird’s ESP-Me and ESP-SMTe modular controllers and is engineered to match their module bay and communication protocol. It will not work with legacy ESP Modular or ESP SMT series controllers, so verify your controller model before ordering.

• Compatible: Rain Bird ESP-Me series and ESP-SMTe series
• Not compatible: older ESP Modular or ESP SMT models
• Ideal for residential and light commercial modular installations

What features and practical benefits does the module deliver?

The ESPSM6 keeps expansion simple and budget-friendly by avoiding full-controller replacement. It preserves the controller’s existing programming, offers reliable station switching, and matches the electrical and physical design of Rain Bird modular controllers.

• Saves cost compared with buying a larger replacement controller
• Maintains current programming and user settings after installation
• Compact module footprint fits easily into available bays

Who is this for: The Arikit-supplied Rain Bird ESPSM6 is aimed at homeowners, landscape contractors, and small commercial property managers who already own a Rain Bird ESP-Me or ESP-SMTe controller and need a compact, cost-effective way to add six more irrigation zones. Choose this module when you want to expand capacity quickly, keep existing schedules intact, and avoid the time and expense of replacing the primary controller. Before purchasing, confirm your controller model is ESP-Me or ESP-SMTe to ensure compatibility.
