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.
| LED behaviour | Meaning | Comment |
|---|---|---|
| Solid Blue | Out of the box first boot | The default mode is Access Point mode |
| Solid White | After Wifi Setup | |
| Slow Green Flash | Docker Image loading | This process will take around 2 minutes |
| Green Flash for 5 seconds | Docker Image has loaded | |
| Red Flash for 5 seconds | Docker Image load has failed | |
| Solid Blue | Remove Wifi information and return to Access Point mode | Hold button for 3 seconds to get to this state |
| Solid Yellow | Preparing for shutdown | Hold button for 5 – 6 seconds to shut down Gravio Hub |
| Short Solid Red | Shutdown | If you keep pressing for 7 seconds, the light will turn from yellow to red and Gravio will shut down |
| Yellow Flash | 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 | No network | Network connection not available – 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.
