Hi, I found this thread and I have similar issues. I have a 6-aero mesh. Rachio worked flawlessly for 3 months. Last week on Wednesday it apparently went “offline”. I was notified yesterday (Sunday) by both e-mail and push notification to my iPhone.
I tried WiFi Reset 4 times, it always stops at Light 3 flashing, and eventually gives an “unexpected error occurred. Try again” message. My Rachio name is Rachio-D4D31F (Serial #VR0699410) . As many here, the Rachio is listed as connected with full bars and “idle” in the eero status page.
In this thread I see a number of recommendations:
- restart the eero network by unplugging the main eero-router
- fix the IP address to a static / private IP of the eero (I guess using the MAC address).
- perform a Hard reset
- Open a support ticket and get connected to the Wifi “experts”.
