Patent ID: 7911326

Claim:
A master generator located in a building to update time data of devices in the building, the master generator comprising: an acquisition module configured to acquire time data representing current time of day; a clock module configured to (i) receive the time data from the acquisition module, (ii) store the time data, and (iii) periodically update the time data; an encoding module configured to encode the time data from the clock module into time messages; a transmission module configured to selectively superimpose the time messages onto a power signal of the building for transmission to the devices; and a load control module configured to generate load control commands based on load control instructions, wherein the acquisition module receives the load control instructions, wherein the encoding module encodes the load control commands into load control messages, wherein the transmission module superimposes the load control messages onto the power signal for transmission to the devices, and wherein the load control module is configured to (i) control a dryer using the load control commands, (ii) receive a humidity signal indicating a humidity level, and (iii) in response to the humidity level being above a predetermined threshold, use the load commands to selectively disable the dryer until the humidity level is below the predetermined threshold.
