ESP programming makes setting up each controller to meet the needs of the landscape easier than ever before. Time is money with Rain Bird helps you keep time on your side.

Postpone Watering

Sometimes the rain comes down and does the watering for you does your current controller take note of the precipitation and adjust for it in the watering schedule. The ESP-Me does. So go ahead and plan that party as far as 14 days in advance Just tell your controller to keep things dry on the days before and the day of the event and it will postpone the watering and automatically restart it's normal schedule the following day.

Bypass Rain Sensor by Station

Rain Sensors are a tremendous invention and they are improving year by year to be more and more smart. However, they fall short in that they control the entire system, not zone by zone. Got Maybe you have an area of your yard that won't receive rainfall the way the rest if the yard does. The ESP-Me controller allows you to identify these special area in your yard, allowing them to water as usual even when the rain is coming down and the other zones are taking a break.

Adjust Watering Up or Down by Percentages

Setting up the perfect watering schedule takes time and finesse. Once you have it just right, the last thing you want to do change up your whole schedule just to meet the needs of a new season. ESP-Me controllers let you increase or decrease your current watering schedule on a percentage basis.

Total Run Time Calculator by Program

There is nothing worse than walking out to the mailbox and having the sprinklers turn on when you are in the middle of the yard! Rain Bird incorporates a total time function into the controller that lets you see how long the entire watering cycle takes and lets you move it up or back accordingly so that your kids don't get a sprinkler-surprise on their way out to catch the bus!

Advanced Warning System

The ESP-Me visually notifies you of problems in the wiring or electronics of the controller by displaying a a bright red LED as well as a scrolling message on the front LCD display panel.

One-Button Watering

Start your system at the drop of a hat with the single push of just one button. No more fiddling with adjustments and overrides, get right to the point with ultimate simplicity.

Contractor Default

Customers and Contractors alike love us for inventing and installing the Contractor Default feature. Just like a factory reset, except it restores the controller back to the optimal programming input by the contractor. Now if a customer fiddles with the settings, you don't have to return to their property to restore the proper watering schedule. Win-Win.

Legendary Rain Bird Design

Rain Bird's famous ESP (Extra Simple Programming) and reliability make this controller a surefire winner.
