Abstract: A power monitoring system is disclosed which enables monitoring of power consumption and optionally control of power delivery. An embodiment of the power monitoring system includes a client device and a server device. The client device includes a power meter, a client-side microcontroller, and a client-side communication transceiver, for transacting with other clients or servers. The client-side microcontroller reads power usage statistics from the power meter and transmits them to the server device. The server device includes a server-side microcontroller that receives the power usage statistics from the client device. Some embodiments of the server-side microcontroller include a LAN/WAN interface, for public or private network access, and a software application that reports the power usage, and offers control opportunities to users on those networks.
