If you’re looking for a multibutton wall switch, there are a few options, although none are officially supported. Personally, I like the smartenIT 3 toggle, which is battery operated and works well. But it only has three toggles, not four.
There’s a Leviton four button wall switch which some community members are using, and an enerwave seven button. Both of those have to be wired to power, though.
You can create what is essentially a mini relay using a $20 Walmart wifi iPhone and SmartTiles, a very popular customizable dashboard app. That gives you a lot of options, but you have to decide how you’re going to power the phone. Either just take it down to charge or add some kind of charging station.
Aeon labs is promising a four button wall-mounted device later this year, but they have a habit of announcing product sometimes years in advance of when they actually come to market so we’ll have to see what happens on that one.
And of course they may someday be official integration with the Lutron device, but again we’ll have to wait to see what happens.
I would say that wall-mounted multibutton controllers is probably one of SmartThings’ weakest areas. many of these devices do exist using a zwave protocol. But most of those work through direct control of the end devices, and that doesn’t fit the SmartThings architecture. SmartThings needs the switch to communicate to the hub, so that they can include both Zigbee and zwave devices in a scene. So this deficiency is one reason why the wall mount tablet or phone dashboards are so popular.
Anyway, lots of things to look at, it’s just going to depend on your specific needs.
