Main page did not showing up any entities


i just end to boot up all my system, i start to copy all my yaml ( gruop,customize ) file to the new system.
i see all the item via unused entities but i do not see any list of the main screen.

what i miss here?

How was your system set up? You may be missing ui-lovelace.yaml as this will setup the actual interface.
However; if you originally configure via the lovelace interface then there is a folder /config/.storage that will contain your original configuration.

The dot . specifies a hidden folder.
