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! 
Walter
