Max Zone Count per Controller

The Rain Bird mobile app is capable of managing and monitoring all available zones that are programmed into a Rain Bird WiFi controller.

ST8-WIFI – Maximum of 8 zones.

ESP-TM2 – Maximum of 4, 6, 8, or 12 zones. Whichever number of zones the controller comes with is the maximum number, there is no expansion option.

ESP-RZXe (international only) – Maximum of 4, 6, or 8 zones. Whichever number of zones the controller comes with is the maximum number, there is no expansion option.

ESP-Me and ESP-ME3 – Comes with 4 zones and can be expanded to a maximum of 22 zones with 3 or 6 station modules, sold separately. NOTE: If a 3 or 6 station module is added to the controller the user needs to go to the +/- Zone icon in the Rain Bird app to change the switch to “Wired” before they can add program run times to the zones.
