Thanks for the clarification. In that case any of the multibutton Devices that work with SmartThings should work for you, including the one pictured in my previous post.
You can take a look at the thread that I linked to there, as well as the buttons FAQ, to see if there’s anything you like:
You could even use the 45631 as long as all of the devices being controlled are Z wave and are within one hop as long as you’re OK with the app not knowing if the devices are on or off since the actions of the wall controller will not be reported to the hub.
