We should not promote entity customization in any way, it is very hacky...

As discussed with Bram I now safe guarded the link to the customization to only be visible for advanced users.
@bramkragten The already existing "Advanced settings" section to override a device entity's location is visible for all users. Correct and by design or should also be safe guarded?
