A system for bidirectional data and power transmission is shown and described. In an embodiment, a network power controller provides power to a node and communicates bidirectionally with the node. In an embodiment, the network power controller is coupled to an AC power source and provides both AC and DC power to the node. In an embodiment, the network power controller and node are coupled via a conduit comprising three wires, wherein the first wire carries DC power and communications, the second wire carries AC power, and the third wire is the neutral/ground line. In another embodiment, the network power controller and node are coupled via a conduit comprising two wires, wherein the first wire carries AC power and communications and the second wire is the neutral/ground line. In an embodiment, AC power having one phase or more can be controlled at the network power controller and the node.
