Across The Great Divide: Lighting And HVAC

First, combining HVAC and lighting in one controller cuts expenses for both controllers and gateways. Because the controllers are fully programmable, instead of application-specific, there is no longer a need to have one controller for each application. This reduces the number of controllers per room to one, instead of two (HVAC & lighting) or more. The same rule applies to gateways. Since the integration is made in-node (inside the controller), extra gateways are no longer required. This also simplifies network architecture and installation logistics.
