Abstract: A system for managing sensors of a building includes a data repository configured to store sensor data from the sensors, a building management system (BMS) controller configured to monitor or control components of the building based on sensor data provided by the sensors, and a sensor diagnostic system. The sensor diagnostic system is configured to receive samples of the sensor data from the sensors, classify each of the samples of the sensor data as faulty or non-faulty, generate supplemental data based on a subset of the samples of the sensor data that are classified as faulty and corresponding attributes of the subset of the samples of the sensor data that are classified as faulty, and provide the supplemental data to the BMS controller to monitor or control the components of the building based on the supplemental data.

Abstract: A sensor management system includes a historical data repository, a building management system (BMS) controller, and a sensor diagnostics system. The historical data repository may store historical data by a plurality of sensors. The BMS controller may control one or more components of a building subsystem based on data provided by one or more sensors. The sensor diagnostic system may receive, from a sensor, sensor data. The sensor diagnostic system may determine at least one fault in the sensor data. The sensor diagnostic system may select, from the historical data repository, substitute sensor data for the sensor based on a comparison of one or more attributes of the sensor data and one or more attributes of the historical data in the data repository. The sensor diagnostic system may provide, in replacement of the sensor data from the sensor, the supplemental sensor data to the BMS controller.
