WiFi Controller Connection When Internet is Not Working
The Rain Bird App does not require an internet connection to talk to the controller if the controller and mobile device are on the same local WiFi network. This means the mobile device is outside of the range of the local WiFi network, then they will not connect.
Also, there are features that will not work unless an internet connection is available (Automatic Seasonal Adjust and notifications are two of those features).
