I have Lutron Caseta, Hue & Wink. The Harmony Ultimate Home is currently controlling the Hue along with the Philips switch. I personally hate the Harmony learning curve, but it mostly does what I want. It forces recreating Hue scenes within the Harmony app which doesn't work as well as the Philips app. When Lutron Caseta has a keypad for controlling Philips Scenes, I'll buy it & dump the Philips switch. don't have a need (yet) to control the Lutron from anything other than the wall dimmers or the phone / IFTTT. Imho, the Lutron setup is well on the way to dominating technically, though there are plenty of examples to show its about marketing, not technical capability.
