Imagine this, you have multiple devices you need to setup, or even if you have a customer that manufactures machines to be shipped out, its not possible to have a guy with an app configuring or connecting to it via Wifi Endpoint, lets just say hundreds of devices (in a large scale)
A solution would be to support unattended installs, an USB Drive that holds a very simple configuration that gets it up and running fx.:
Account Settings (What is needed to link an account/customer to the device)
Wifi Settings
Sim (4g) Settings
Deployment Server Settings
HEC Endpoint
And even possibility to tell the hub which Docker Containers to run, if a compose file is present on the USB Drive (Copy it over and execute)
