So my friend has a dual dumb switch in a single gang we were looking to swap into a smart switch.
Came across this sonoff which of course runs off ewelink

I was not sure if there was any other hardware that’s two channel single gang more native to smartthings?
If not I’m pondering to alexa/iftt it into smartthings
Tia!
Neo has a zwave one which some community members are using. It’s not really intuitive, because it’s two buttons one above the other and most people will think the top button is on and the bottom button is off rather than that each button toggles a different device. But it does seem to work.

Otherwise, you may be able to use one of the dual micros behind the existing switch.
