Multichannel Problem with Z-Uno

I recently got hold of a Z-Uno, and added it as a Thing to my hub as a Multi Channel device. The inclusion was successful, and I can Include and Remove okay. I can only see and control one channel, despite declaring five channels within the Z-Uno, which can support up to 10 channels. Is there a need to write a Device Handler? Bit lost as to the next step.

Looks like you need to write own Device Handler or pick up some handler from another popular multichannel device (try at least with two channels).
