That’s a custom “Device Type Handler” (DTH) Written in groovy. Using it will expose advanced features of the device that just using a stock DTH will not. When a manufacturer or retailer recommend you use one, it’s usually a good idea. And if the smartest house or Inovelli recommend you use one, definitely do.
The following FAQ is old, but it will teach you the basic Terminology and concepts for what you’re going to do. Basically it’s just cut and paste.
You just need to read the sections on device type handlers, not the sections on smartapps. (The topic title is a clickable link)
