Abstract: The system may include determining a number of occupants in a space, based on input from one or more sensors and an artificial intelligence classifier; creating a thermal model of the space based on the number of occupants, data about an outside temperature from an outside surface of one or more walls of the space, data about an inside temperature from an inside surface of one or more walls of the space and data about wall insulation for one or more walls of the space; predicting, using the thermal model, a temperature in the space for a period of time to create a predicted temperature; predicting a thermal comfort using a predicted mean vote (PMV) model and based on the predicted temperature; creating adjustment instructions for a building management system (BMS) based on the thermal comfort; and sending the adjustment instructions to the BMS.

Abstract: The system includes a wireless network that combines the functionality of the sensors with the formation and maintenance of the network, while balancing the network with the minimization of the energy consumed by the entire system. The system may include nodes, gateways, coordinators, extension sensors and boosters. The system may perform a method comprising applying a known load to a battery in a first node; measuring a voltage drop in the battery; determining an internal resistance of the battery; estimating a remaining life in the battery based on the internal resistance; and in response to the remaining life being below a remaining life threshold, re-directing, by a first gateway, signals in a mesh network away from the first node and to one or more of a plurality of nodes interfacing with the first node, wherein the first gateway interfaces with the first node and a network.
