Rain Bird ESP-Me Controller Gives You Flexible and Smart Control Over Your Irrigation Systems

Whether you’re installing for a residential client or a light commercial job site, the Rain Bird ESP-Me controller is designed to give you the versatility you need. The more stations you add, the more you save, providing you and your customers with more value for the money.

Extra Simple Programming Makes the Rain Bird ESP-Me the Only Controller You’ll Ever Need

For more than 70 years, the world’s top irrigation contractors have chosen Rain Bird for the highest quality products and services available worldwide.

Rain Bird believes in the Intelligent Use of Water™ and develops products and technologies that use water efficiently. The ESP-Me is no exception. Building on Rain Bird’s legendary Extra Simple Programming, the ESP-Me controller offers a broad range of water-saving features that are so easy to use. This controller gives you the highest station count in its class and new features so easy to use that you’ll actually use them. With the freedom to install the same controller on various sites, you will grow your customer base like never before.

Best of all, you can upgrade the ESP-Me by simply installing an LNK™ WiFi Module without having to replace the entire unit.

Make your controller SMART by adding the EPA WaterSense labeled LNK WiFi module and WR2 rain sensor.

Tailored Watering Schedules
Extra Simple Programming makes it easy for you to meet each landscape’s unique needs.

Single-Controller Simplicity 
The ESP-Me can do it all, saving you valuable time and labor. The scalability of the ESP-Me and the choice of installing either 3 or 6 station modules mean more flexibility for any landscape.

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 the entire landscape.

Seasonal Adjust by Program
When the seasons change, change with them. Reduce watering to as little as 5% of your scheduled program times or increase it to 200%. Apply to all programs or 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-Me visually notifies you of electrical and programming issues with a bright red LED and scrolling messages across the LCD display. The ESP-Me controller will reset or clear when the error is corrected.

When an electrical error is detected, irrigation for the affected station is canceled, and watering advances to the next operable station in the program.

The controller will attempt to water the affected station again at the next scheduled watering. Completing a successful watering will clear the error condition associated with that station.

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

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
The new ESP-Me is easy on the eyes, featuring vibrant colors, an intuitive dial, and a bright LCD. And with legendary Extra Simple Programming and the Rain Bird reliability you trust, it’s the same easy setup, just better.

The indoor model comes with a wall plug-in transformer that can only be used for indoor mounting, while the outdoor model comes with an internal transformer and lead wires for direct wiring to your power source. The outdoor model can be used either outdoor or indoor.
