It's possible, but I think that would be unlikely; the "customer code" (also known elsewhere as the "device code") shown in the Dune website is the actual code used within the NEC protocol itself for their devices. There are, however, dozens of different protocols out there, with many different mechanisms for identifying manufacturers and devices; moreover, there's no system for ensuring that a given device code is unique. In short, it's a real mess.

I'll throw the Dune command set into Pierogi too, though, just in case.
