APPARATUS AND METHOD FOR SELECTIVELY COUPLING A DALI-COMPATIBLE CONTROLLER AND/OR A DALI-COMPATIBLE POWER SUPPLY TO A DALI NETWORK BUS THROUGH A POWERLINE INTERFACE OF A SMART CONTROL DEVICE

A smart control device includes a processor, a memory, a powerline interface, a power supply compatible with a Digital Addressable Lighting Interface (DALI) protocol, a first controller, a second controller, and configuration circuitry. The powerline interface has a set of primary contacts (Line, Load, and Neutral) and a set of secondary contacts. The set of secondary contacts includes a first pair of secondary contacts and a second pair of secondary contacts. The configuration circuitry is arranged to selectively couple (a) an output of the first controller to the first pair of secondary contacts (e.g., when there is no output from the second controller) or (b) an output of the second controller to the first pair of secondary contacts and an output (or outputs) of one or more of the first controller and the power supply to the second pair of secondary contacts.
