As an alternative, you might consider using Philips Hue Tap Dials. This remote has a rotating control on the outside as well as four buttons. I created an HA blueprint that allows for single tap and long press for each button as well as customization of how the volume control works.
If you look down a few posts in the thread, you can see me iterating on using stickers to customize the look of the control. The first attempt wasn’t great, but the second attempt was pretty good though it requires a Cricut cutter.
This is more complicated than the Lutron approach because it requires the use of Zigby2MQTT including a Zigby antenna.
I’m traveling on vacation through early April and in areas with little or no reception. I may not get back to this thread for a while.
