The Gravio Logo on the Gravio Hub can light up in various colours and patterns. Here you can find what the colours mean and/or how you can trigger them.
|Solid Blue||Upon boot||Out of the box first boot||The default mode is Access Point mode|
|Solid White||Upon boot||After Wifi Setup||Boot successful, in operation|
|Slow Green Flash||While booting||Docker Image loading||This process will take around 2 minutes|
|Green Flash for 5 seconds||While booting||Docker Image has loaded|
|Red Flash for 5 seconds||While/after booting||Docker Image load has failed|
|Solid Blue||After booting||Could not connect to Wifi. Wrong password? Wifi not present?||Hold button for 3 seconds to reset Wifi information and re-connect to Gravio Hub Wifi and setup screen 192.168.100.1:8080|
|Solid Yellow||While shutting down||Preparing for shutdown||After holding button for 5-6 seconds to shut down the Gravio Hub|
|Short Solid Red||While shutting down||Shutdown||If you keep pressing for 7 seconds, the light will turn from yellow to red and Gravio will shut down|
|Yellow Flash for 5-6 seconds||After booting||Could not retrieve NTP information||The Gravio Hub did not manage to retrieve NTP (network Network Time Protocol) data, most likely due to not having a connection to the public internet|
|Solid Yellow||After booting||No network||Network connection not available / no IP address – perhaps wrong Wifi details?|
You can turn the Gravio Hub into the Acces Point Mode to access it via Wifi, if you lock yourself out. To do that, press the button while it is running, until it turns blue, then release it while blue.
