Does Smarthings control Caseta?

I understand that Smartthings doesn’t have a Clear Connect radio. But I also understand that it now is connected to Harmony Home which can control a Lutron Bridge.

So, I guess I’m asking is if I had a Lutron Bridge and Harmony Home, would Smartthings be able to control both?

Has anyone had any success controlling Lutron Caseta? Right now it’s they only reason I have the wink hub plugged in… For a single wall switch. Ugh. Was hoping integration with Smartthings would have happened by now.
