System for distributing DC power to and controlling building devices

A system for controlling and distributing DC power comprising:

• a power hub comprising:
• a hub controller;
• a power converter adapted to convert AC power to DC power;
• one or more variable voltage regulators operatively connected to the power converter and controlled by the hub controller, the one or more variable voltage regulators are operable to provide regulated DC power to one or more primary loads and to receive and transmit data and control signals from and to the one or more primary loads;
• one or more communication interfaces operatively connected to the hub controller to transmit and receive data and control signals over a network;
• and
• a load control module comprising an input port for receiving DC power and control signals through the input port and send information monitoring signals, sensor data and processed sensor data out from the input port wherein the load control module is operable to use all or a subset of output ports to apply DC power to a secondary load that is operable connected to the load control module.
