Indeed you can. I didn’t mention in that post, but if you have the SmartThings app open, you can see the dimming slider moving as you rotate the dimmer or adjust dimming with the remote. You can also see the state change to OFF when you turn the dimmer all the way down, toggle with the remote or the motion sensor turns off the bulb(s).
However, the UI does not seem to be accurate where multiple bulbs are concerned, but if one were linked to the other(s) that might not matter.
