I have both the Hue switches and the Cooper RF9500.
I find the Hue switches are great for selecting scenes (comprised of only Hue bulbs) and as an added benefit, they do not (specifically the Tap) require batteries. But they do not quite fit the bill for a normal looking wall switch and they leave my non-Hue lights in the dark. Also, the Cooper switch definitely looks the part.
Moreover, the Cooper switch can be used to trigger any number of events through ST. I have some of them triggering music on my Sonos, adjusting my shades, or triggering a combo of events… Might be worth a consideration.
Open smart lighting and see if the Cooper shows up as a light switch or as a button controller. (I depend on text to speech, so I can’t read code and I don’t know what the “capabilities” are in the device type handler you chose.)
It may even show up as both.
When you start a new smart lighting automation the first thing it asks you is what lights you want to control. If the Cooper shows up on that list, it’s a switch.
After you select something from that first list, it will ask you how you want to trigger that switch. Select button pressed. If the Cooper shows up on that next list, it’s a button controller.
Did this work for you? I haven’t tried that device handler, but if you are registering button presses, you should be good to link them into supporting smart apps. I’m using @thegilbertchan - "Cooper RF9500 (all buttons) device handler. I pair it with the Button Controller app.
Looking at the EricVitale RF9500 - Beast app, it appears to support both switch and button capabilities. Should also work with the Button Controller Smart App.
