Rain Bird ESP-4ME3 WiFi-Compatible Indoor/Outdoor Sprinkler Controller

ESP-4ME3 Indoor/Outdoor WiFi Compatible Controller

With 4- to 22-station scalability, the ESP-4ME3 helps you better serve your customers. Install the same controller on residential and light commercial sites -- the more stations you add, the more you save, providing you and your customers with more value for the money. Best of all, you can upgrade existing ESP-4ME3 installations by simply installing a new WiFi-compatible front panel and LNK™ WiFi Module, without having to replace the entire unit.

WiFi Connectivity

By simply plugging in a Rain Bird LNK WiFi Module (sold separately), users can access, operate and monitor their irrigation system from anywhere. Internet-based weather information is used to make daily adustments to the irrigation schedule, saving up to 30% in water. 

Tailored Watering Schedules
Extra Simple Programming makes it easy for your crew to meet each landscape’s unique needs. With the controller up and running faster than ever before, you’ll get more jobs done in less time.

Single-Controller Simplicity 
Forget training crews to install different controllers. The ESP-4ME3 can do it all, saving you valuable time and labor costs. The scalability of the ESP-4ME3 and the choice of installing either 3- or 6-station modules mean more flexibility and a competitive edge.  

Delay Watering
Is Mother Nature doing the watering for you? Are you having a party and want to make sure the landscape is dry? Easily postpone irrigation for up to 14 days. Normal irrigation will resume automatically.

Bypass Rain Sensor by Station
Got a landscaped area under an eave or deck? Bypass the rain sensor for that station(s)—or for the entire landscape.

Seasonal Adjust by Program
When the seasons change, change with them. Reduce watering down to as little as 5 percent of your scheduled program times or increase it up to 200 percent. Apply to all programs or to each program individually. 

Total Run Time Calculator by Program
Calculate the specific amount of time the controller is scheduled to run for a given program. Use it to ensure morning watering is finished before the family wakes up, or reduce your run time to comply with water restrictions.  

Short Detect/Programming Errors
The ESP-3ME3 visually notifies you of electrical and programming issues with a bright red LED and scrolling messages across the LCD display. 

One-Touch Watering
Need an easy way to turn on the system? The ESP-4ME3 offers one-touch watering. With the dial in the AUTO position, just press and hold the right teardrop arrow button.

Contractor Default™
Prevent callbacks with Contractor Default™. Simply save your programs after setup. If the original watering schedule is overwritten in error, easily restore it in just two steps. 

User-Friendly Rain Bird Design
Featuring vibrant colors, an intuitive dial and a bright LCD display, the new ESP-4ME3 is easy on the eyes. And with legendary Extra Simple Programming and the Rain Bird reliability you trust, it’s the same easy setup, just better.
