Customized for your yard, climate, and sprinkler system

Our controller waters based on the moisture in your soil and what your yard needs. We skip watering when it rains and if your soil has enough moisture for your lawn's roots and plants. No need to be a plant expert – we'll do that for you.

Quick & Easy Setup

Install in 30 minutes or less with no special tools needed. Our in-app install tutorial helps you watering in no time!

Smart Schedules

Watering schedules automatically adapt to your preferences, soil moisture, climate, and the season for unparalleled accuracy.

Water Savings

Rachio 3 is an EPA WaterSense labeled device, which means it is at least 20 percent more water-efficient than average controllers.

Intelligent watering for any outdoor space

Your yard is unique, so it shouldn't have to settle for one-size-fits-all watering. Give your yard what it really needs in the Rachio app:

Real-Time Water Changes

Plants naturally use more or less water throughout the seasons. We automatically adjust for that, saving you water while creating healthy plants.

Run Zones From Your Phone

Use your phone like a watering remote: select any zone to run or pause watering and more.

Troubleshoot your Sprinklers

Easily get to the root of most yard woes with our troubleshooting tool. Identify issues like lawn diseases, test sprinkler head coverage, and even make irrigation maintenance easier – all from your mobile device.
