The Rachio 3 has updated hardware and memory that allows you to control your device from your HomeKit. But what happens if your HomeKit is not responding?

There are a few troubleshooting steps you can take to get your HomeKit and Rachio 3 to work together again, such as verifying the network you are using and resetting the device. However, Rachio 3 currently has some isolated known issues with HomeKit, which may also be the source of your problems.

While there are some isolated issues, many successful users have been able to get their HomeKit and Rachio 3 working in sync again with no problems. We will walk you through how to follow some of those basic troubleshooting steps to help you fix your HomeKit and Rachio 3 connection.

Rachio 3 and HomeKit Basic Troubleshooting

Let’s walk through some of the basic troubleshooting steps first. Taken from Rachio’s help page, we’ve expanded the instructions for you a bit to make sure you fully understand the troubleshooting process.

  • Verify Your Rachio 3 Is On – You can look at the front of the controller and make sure that the blue bar is actually lit up. The other option is checking your Rachio app and making sure that it’s on. Simple, right?
  • Verify the Networks Are Compatible – Okay, so your Rachio 3 is definitely powered on. Next, verify the controller and that at least one device is connected to the same Wi-Fi. Rachio 3 needs a device that stays at home and is connected to the same Wi-Fi.

Pro Tip: Sometimes, a house can have 5G Wi-Fi and regular Wi-Fi. Ensure that at least one device (Apple TV, phone, iPad) is connected to the same network as your Rachio 3.

Remove and Re-Add Rachio 3

If you’ve checked the box on the first two steps, it’s time for a small reset. Before you do the full reset, try disconnecting Rachio 3 from your HomeKit and then reconnecting.

To remove Rachio 3 from the HomeKit, you need to follow these steps:

  1. Open the Home app. (You should be using a device that belongs to an administrator.)
  2. Select “Rooms.”
  3. Choose the room you chose for Rachio 3 to belong to.
  4. Select the Rachio 3 device.
  5. Hit “Details.”
  6. Scroll to the bottom of the details and tap “Remove Accessory,” and confirm your choice.

To add your Rachio 3 back, you will add a HomeKit Accessory and then follow these steps:

  1. Tap “Don’t Have a Code or Can’t Scan.”
  2. Select your Rachio 3.
  3. Use your HomeKit Code.
  4. Choose the room and the name for Rachio 3.

Sometimes, a simple reset will do the trick to get your Rachio 3 and HomeKit compatibility back on track.

Factory Reset

So, you’ve done all the steps above, and your Rachio 3 still isn’t responding. Now it is time to bring out the full reset.

When you factory reset your Rachio 3, make sure to disconnect it from HomeKit. Otherwise, you may have two Rachio 3’s on your HomeKit: one that works and one that doesn’t. Follow the instructions in “Remove and Re-add Rachio 3” to remove from HomeKit. Once you’re done factory resetting it, you can add it again.

The one problem with factory resetting is that it will take away all the data you have set up. However, this method has worked for quite a few people. Make sure to have your data written down somewhere or copied so you can easily add it again.

Factory Reset Using the App

The first way to reset the Rachio 3 is to use the app. Follow these instructions to factory reset your Rachio 3:

  1. Open your Rachio app on your phone or tablet.
  2. Select “More.”
  3. Tap “Controller Settings.”
  4. Scroll down and select “Remove Controller.”
  5. Read and acknowledge the warning and select “Remove.”

Note: This will only work if the controller is online. If it is offline, you will need to use the controller to reset.

Factory Reset Using the Controller

The second way to complete a factory reset is using the controller. To successfully factory reset your Rachio 3 using the controller itself, follow these instructions:

  1. Unplug your Rachio 3.
  2. Plug it back in.
  3. Wait for it to restart completely.
  4. Hold down the stop button until the light bar comes on and flashes blue.
  5. Rachio 3 will go through a couple of steps and finally flash red.

Note: You will still need to delete the controller from the app if you want to remove it from your ownership completely.

Update from Rachio 3 Community Thread

If you completed all the steps above and your Rachio 3 is still not responding, you may fall into the group of people affected by current isolated errors. HomeKit is a newer integration for Rachio, only available on Rachio 3. The manufacturer is working to continue upgrading this integration and will push out firmware when the update is complete.

Final Thoughts

We know it can be frustrating when HomeKit and Rachio 3 do not get along anymore. If your Rachio 3 is not responding, you can follow the above troubleshooting steps. If these don’t work, you may need to keep an eye out for the updated firmware Rachio will be releasing.
