Patent ID: 8457179

Claim:
A device for building monitoring, comprising: a first transceiver coupled to a first phase of a power system of a building and configured to receive and send data over the first phase of the power system, wherein the data received over the first phase of the power system by the first transceiver includes data from a first sensor; a second transceiver coupled to a second phase of the power system and configured to receive and send data over the second phase of the power system, wherein the data sent over the second phase of the power system by the second transceiver includes data sent to a control device; a third transceiver coupled to a third phase of the power system and configured to receive and send data over the third phase of the power system, wherein the data received over the third phase of the power system by the third transceiver includes data from a second sensor; and a switch coupled to the first, second, and third transceivers of the power system and configured to route data between the first, second, and third transceivers of the power system, wherein the data routed between the first, second, and third transceivers of the power system includes: the data from the first sensor being routed from the first transceiver to the second transceiver; and the data from the second sensor being routed from the third transceiver to the second transceiver; and wherein the data sent to the control device over the second phase of the power system by the second transceiver includes the data from the first sensor and the data from the second sensor.
