Abstract: A system and method for data-driven HVAC optimization for outputting HVAC setpoints to a thermostat and determining a predicted HVAC usage of an HVAC unit based on the HVAC setpoints and an outdoor temperature. The system may further determine and output a predicted cost of the HVAC unit heating or cooling a structure based on the HVAC setpoints. The system may further select optimized HVAC setpoints such that the predicted cost is less than or equal to a user defined cost constraint and minimize deviation from user-preferred HVAC setpoints.

Abstract: A decoding method for biphase-encoded data is provided. The decoding method includes detecting falling-edge transitions in the biphase-encoded data to decode according to a time difference (?t) between each two adjacent falling-edge transitions and the logic value of previous bit. When ?t is 1 bit period and previous bit is logic 1, it's determined that present bit is logic 1. When ?t is 1 bit period and previous bit is logic 0, it's determined that present bit is logic 0. When ?t is 1.5 bit periods and previous bit is logic 1, it's determined that present and next bits are both logic 0. When ?t is 1.5 bit periods and previous bit is logic 0, it's determined that present bit is logic 1. When ?t is 2 bit periods and previous bit is logic 1, it's determined that present and next bits are logic 0 and 1 respectively.
