No special tools or expertise required to install!

The Rachio 3e is compatible with almost any sprinkler system, and installs easily with our app-guided setup and one-touch connectors. Breeze through installation in 30 minutes or less with three easy steps.

Or, skip the DIY and find a Certified Rachio Pro to install your new controller.

Step 1: Replace your old controller.

Test your sprinkler system and remove the old controller, then mount your new Rachio (our handy mounting template can help save time!)

Step 2: Plug existing wires into Rachio.

Easy-press terminals help you quickly snap into place – no screwdriver needed! Match the wires from your old setup for ready-made wiring.

Step 3: Complete setup in the Rachio app.

The streamlined Rachio app helps connect your controller to Wi-Fi and then customize your zones and watering schedules.

Control and monitor your yard's watering within the Rachio app.

Watering isn't one-size-fits-all and you shouldn't have to settle for one-size-fits-all lawn care. Using the Rachio app, you can:

  • Automatically avoid watering in the rain or when your yard doesn’t need water
  • Customize each zone by plant type, soil type, sun exposure, slope, and spray head
  • Choose between two unique schedule types
  • Ensure your schedules are running when you and your yard need it
  • Get tips and view historical and upcoming watering
  • Monitor your water usage from wherever you are in the world

Weather Intelligence™ automatically skips unnecessary watering with features like Rain Skip, Wind Skip, Freeze Skip, Saturation Skip, and Seasonal Shift. Plus, our Smart Cycle feature will help prevent runoff by breaking up watering time and allowing water to soak into the soil before adding more.

See results in as little as four weeks.

Taking control of your watering isn't an overnight fix for your lawn. But over time, Rachio will help your yard grow stronger and healthier.
