Can the Harmony Hub binding control Lights and Switches paired with the hub?

Is it possible to control lights and switches that have been paired to the Harmony Hub?

I noticed that they don’t appear in the inbox when I’ve added my Harmony Hub as a Thing.

I know it sounds a little weird, but I cannot get the Lutron Caseta to work with Plex, and this seemed like a viable workaround.

No one has any input on this one? I’d really appreciate the help!
