Ability to archive devices (offline ones for example)

Many of my devices are offline for various reasons and it would be nice to be able to archive devices to hide them for the main dashboard. (useful for the update process to avoid getting errors)

It would also be important to be able to un-archive them once they are installed/used again.

Start by tracing how devices are listed on the main dashboard and how the update process handles offline devices. Define how archived status is set and cleared, then verify that archived devices stay hidden without causing update errors and that un-archiving makes them visible and usable again.
