Try my universal dimmer driver. I think that switch should support the features needed to scan and present all the settings. I could not tell from a quick search what z-wave chip they are using in it currently. There is possibly a setting you need to change to enabled the "scene" (button) presses.
Also if you don't mind, post the entire "Data" section from the bottom from the device page. I think one of the values there will let me figure out what chip/protocol it is using.
