Your device lights are most important during the setup and installation of your iFLO device. It is normal that they shut off after your device is setup and it does not mean there is an issue with your device.
After installation, the device lights function as a method of communication from your device to your app to the server.
A few examples of when they will illuminate; when getting ready for a dispense, if your battery is low or if you need a new bottle. Otherwise, they will remain in their battery-saving mode.
