Using @Cobra's driver (which can be accessed by registering at his site https://cobra-apps.co.uk/), it is very easy to set up a button tile which then drives the switch state (up to 4 are allowed) which can be reported in another tile. This is the one I set up for my dog bark (which has 3 states; off, on, and away). It works perfectly and I think the UI is good enough. It would be better as 3 radio buttons of course.... 
@chillibenny fyi above, hope it helps. Cheers.
