Demand/response mechanism in a wireless sensor network
A wireless sensor network at a monitored location can be configured to generate sensor channel(s) of data to assess operational conditions at the monitored location. Inputs based on the sensor channel(s) of data are provided to a host system for analysis of a demand to one or more resources at the monitored location. Response messages can be generated based on the demand analysis and transmitted to actuator(s) at the monitored location to effect an adjustment to the operational conditions.
1. A wireless control device, comprising:
a wireless communication subsystem that enables the wireless receipt of a control message generated by one or more servers in a host system remote from a building in which the wireless control device is installed, the control message generated by the host system based on an analysis of sensor data measurements generated by one or more sensors in the building, the host system communicating the control message to a device in the building via an Internet connection supported via an Internet service provider; and
an actuator subsystem connected to the wireless communication subsystem via a wired communication interface, the actuator subsystem configured to receive control information, which is based on the control message, and to initiate, in response to the received control information, transmission of a response action control signal to an actuator device in the building for control of a physical environment condition in the building.
