In each device/room step, a device factory process is called. We call subsequent device factory methods in the various libraries that make up Essentials until one of them returns a functional device. This allows us to break up the factory process into individual libraries, and not have a huge master list of types and build procedures. Here's part of the code: In each device/room step, a device factory process is called.

In each respective factory, or device constructor, the config's properties object is either converted to a config object or read from using `JToken` methods. This builds the device which may be ready to go, or may require activation as described above.
