Recently, my Rachio controller is showing “disconnected” in my Google Home interface. It’s still working and doing it’s job, but to get it to show connected, you need to either reconnect your Google Home account with Rachio or refresh the controller inside the Rachio app. However, I thought maybe Rachio was changing their integration with Google or something else, but it’s persisted for about 3 months. Is this a known issue? what steps could I take to reset the integration and have it show connected?
Hi @wqcoleman, welcome to the Rachio community forums! I double checked our Google Home “Rachio Smart Sprinkler Controller” action and did not immediately see any issues around the “offline” status on our side.
Based on your description, I also performed the following test with my own personal controller which you could try as well if you’d like to validate the “connected” status.
- I opened the Google Home app and confirmed my controller was in the devices tab and working
- I physically unplugged the controller and waited 5 minutes to force it to be offline
- I closed and reopened my Google Home app and confirmed the device was now marked as “offline” as expected
- I plugged my controller in again and waited 5 minutes for it to come online.
- I closed and reopened my Google Home app and confirmed the device was no longer offline and responded to commands again.
Let me know what you find!

Hi Walter! I am also having the problem of my Rachio Gen 2 Controller showing up as offline in my Google Home App. This happens even though my controller is online and controllable within the Rachio App. I have tried unlinking Rachio from Google Home and then relinking but the problem persists. I have also reset my wireless network without any success.
I started noticing recently the Controller start showing offline even when the controller is online and working fine on the Rachio app. I have unlinked and re-link the account and started noticing there are now 2 options, one for the Hose and one for the Controller. I tried the hose one and I can see my Hose connected just fine on Google Home, but when I try the other option for controllers, it takes a bit to display the login screen and then it does the integration just fine however the controller shows “offline” right after hence cannot do anything via GH
Are those 2 integration options expected and live?
@wqcoleman @ascernas did you ever receive any response from Rachio on this post? I’m experiencing the exact same issue. I removed the Rachio 3 from my GoogleHome app and when I try adding it back, (Rachio Smart Sprinkler Controller), it goes thru the process to link the account, I login, allow google and when it goes back to Google Home app, it says “could not reach Rachio Smart Sprinkler Controller, try again later.” Within the Rachio app it works fine and shows connected but doesn’t connect to GoogleHome anymore. I also had this on my Apple phone but read in the community here that they stopped supporting Apple HomeKit. Perhaps now they also stopped supporting GoogleHome???
negative. I think there is a problem with their API and Google Home. It worked great for two years and the last six months it’s been basically disconnected in Google home, tho again, it works fine on it’s on. I never use it from Google home, only that i like everything integrated and working.
@wqcoleman - yea, same here… especially when they advertise that it works with GoogleHome. I saw that they offered refunds back to Apple HomeKit users… maybe they will do the same.
Negative. I have tried many times un-linking and re-linking the account named “Rachio Smart Sprinkler Controller” and the integration process works fine, however when the devices show up on the Google Home app, instantly shows “offline” and if I access it tells me “Couldn’t be reached”.
I tried rebooting my entire network several times and every single integration I have with Google Home app works fine, even the one with the Rachio Smart Hose Timer" is working as it should (which is a separate integration).
So, I read the suggestion about turn off the controller for 5 mins and then 5 more mins wait, that does not make sense as the Controller works fine with the Rachio app and the other integration works fine with a device on the same network, same account, same app and same location.
And this has been working fine for the time I have the Controller (more than 3 years), and just started happening these past months, so there must be something within the integration that is broken, and we need support for that. Hope they can see this.
I have the same issue. Rachio is online in app, however google home shows that this is offline. Also tried unlinking and relinking, power recycling the controller etc.
@walter… maybe Google made some changes to the API or your API is not refreshing properly? That said, where there is smoke, there is fire… any update for us?

Thanks for all the followups - I took a look at the Google documentation, and there were definitely some updates around September 2024. I made a small update this morning (2/12/25) to include a new field I noticed.
Could you check and let me know if you’re seeing any differences? If the issue persists, I have a few other ideas we can try next as well.
Appreciate your patience.

@walter thanks!! I’ll check this. This morning it was still offline, but I re ran the Google integration process and it’s online now. So, let’s see what happens over the next few days.

Hi Walter. It looks like we are one step closer but still having issues. I was able to add the Rachio sprinkler system thru the Google Home app using “works with google.” But once added, it immediately went offline. The last time I tried this it wasn’t even linking to the Google Home app but now that it’s letting me, it’s now showing offline.
