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:
```
// Try local factory first
var newDev = DeviceFactory.GetDevice(devConf);
// Then associated library factories
if (newDev == null)
newDev = PepperDash.Essentials.Devices.Common.DeviceFactory.GetDevice(devConf);
if (newDev == null)
newDev = PepperDash.Essentials.DM.DeviceFactory.GetDevice(devConf);
if (newDev == null)
newDev = PepperDash.Essentials.Devices.Displays.DisplayDeviceFactory.GetDevice(devConf);
if (newDev != null)
DeviceManager.AddDevice(newDev);
else
Debug.Console(0, "ERROR: Cannot load unknown device type '{0}', key '{1}'.", devConf.Type, devConf.Key);
// Try local factories first
var newDev = DeviceFactory.GetDevice(devConf);
if (newDev == null)
newDev = BridgeFactory.GetDevice(devConf);
// Then associated library factories
if (newDev == null)
newDev = PepperDash.Essentials.Core.DeviceFactory.GetDevice(devConf);
if (newDev == null)
newDev = PepperDash.Essentials.Devices.Common.DeviceFactory.GetDevice(devConf);
if (newDev == null)
newDev = PepperDash.Essentials.DM.DeviceFactory.GetDevice(devConf);
if (newDev == null)
newDev = PepperDash.Essentials.Devices.Displays.DisplayDeviceFactory.GetDevice(devConf);
```
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.
