Nice device! It’s using multi channel association. This didn’t used to work well with SmartThings, but now it works OK, although you will need custom code to set each button correctly.
You should be able to use the device type handler for the 24 function Fibaro handheld remote as a starting place.
You’ll also probably need the Z wave Tweaker to set the associations to begin with
All of which is to say that it’s not going to work straight out of the box, but it looks like someone should be able to create a custom device type handler which will be able to work with it once you set the associations appropriately.
