As long as Glow is plugged into an outlet, it will try to reconnect via WiFi. You can see it searching as it is blinking the Air Status Indicator light.
If your Glow loses connection, your triggers will be saved the next time your Glow gets online. You will not need to reset up the triggers again.
If you selected 'Automatic Shutoff' on from the Settings icon, your Awair Glow will automatically turn off the connected device after 30 min when Glow has lost internet connection. All users are automatically opted-in for this feature.
