Unfortunately, units with the incompatible firmware are still on dealer shelves.
If you have a Mac laptop or desktop, use that to connect the Rachio ‘accessory’ to your Google Wi-Fi.
With a Windows or Linux PC, you need to do some command line stuff:
Or, use an older phone or tablet to connect.
Once connected, Rachio will update its firmware and your iPhone will work to reconnect if needed.
