A mesh-networked sensor platform has a mesh network of nodes that connect with existing electrical infrastructure or are powered through other means such as batteries or energy scavenging. The mesh network forms a self-healing and self-configuring network robust against individual node failures. Wireless mesh networking integrated circuits (ICs), energy monitoring ICs and solid state relays are used to create a low-cost, easy-to-install energy visualization and management system. The system can intelligently control energy usage at the sockets to stop energy from being wasted. Software for a central base station uses energy usage data from each node to create an energy usage profile to automatically detect anomalies in energy usage and take steps to correct them. Other sensors can be easily added for a multitude of applications. Power usage and control of each appliance can be viewed via an internet connected PC or smart phone via a social networking website.
