The Lutron aurora dimmer, which is the one I had in the picture, is a nice device. As I mentioned, we have several in my own home. But they don’t work with just a smartthings hub. You need to use a hue bridge with them, and when you do, they are not exposed to smartthings so smartthings doesn’t even know they exist. They just become a physical switch on the wall. So they can only work with Devices which the hue bridge also controls. They could work with Hue bulbs or IKEA Tradfri bulbs. But unfortunately not with your Sylvania bulbs because those use a different zigbee profile. Those can connect to the smartthings hub, but not to the Hue bridge.
