How do I install a Generation 2 Rachio outdoors?

Controllers can be mounted indoors or outdoors. If outdoors, they're usually hardwired and can be a bit tricky to change out. The Rachio Smart Sprinkler Controller, Generation 2 has a custom outdoor enclosure that makes it easy to swap out an existing controller and have a clean, elegant looking outdoor controller that can be locked up and hardwired.

Installation Steps:

Before installing this fixture or removing a previous fixture, disconnect the power by turning off the circuit breaker or by removing the fuse at the fuse box. Not into playing with wires? No worries! Complete the form below to be connected with a local RachioPro!

Install the enclosure

  1. Take photos of your wiring and label any duplicate colors to avoid confusion
  2. Remove the old enclosure and controller from the wall
  3. If you have wiring conduit coming into the old enclosure, make sure to account for any fittings and/or space requirements that differ on the Rachio enclosure
  4. If the conduit does not align, cut and re-route as needed
  5. Mount the Rachio enclosure to the wall; if mounting to drywall, use anchors

Connect Power

The controller will use the supplied power adaptor for both outlet and hardwire applications; connect the power using one of the two methods below:


Parts Needed (not included)

First, you’ll need a couple of extra parts that are readily available on Amazon or at a local hardware store.  We recommend the following:

Here’s what you should have to get started (power cord not needed if hardwiring the power):

1) Unscrew the two screws on the lid of the Hardwiring Bay to access the enclosure wires of the outlet.

2) TURN OFF POWER to your hardwire power source. Clean and straighten the wires. Attach a strain relief bushing (not included) if you have slack in the wire -or- if you're installing a pigtail. Position the bushing about an inch below the beginning of the black insulation.

3) Feed the power supply wires through the bottom left hole of the enclosure.

4) Attach the wires using connector caps

5) Black (or red) supply wire to the black enclosure wire. This is your power supply wire, also known as "hot".

6) White supply wire to the white enclosure wire. This is typically the common/neutral wire.

7) If you have a ground wire (usually green), attach it to the enclosure ground wire

8) Wrap all wire connections with electrical tape for a secure connection.

9) Close Hardwiring Bay of the outdoor enclosure with the cover and two screws that came with the enclosure.

10) Mount the controller

  • Pull valve and sensor wires through the center opening on the controller's base. Mount the controller to the enclosure using the included bolts
  • Mounting holes: top center + two bottom (do not use the center middle)
  • DO NOT install the cover on the base of the controller after it's mounted in the enclosure.
