Abstract: Network-based systems for monitoring geographically distributed electromechanical equipment, such as a supermarket refrigerator case or walk-in freezer. Systems includes a number of monitored sites, each in data communication with a separate data analysis facility, each facility in turn with its own data storage. All data analysis facilities are in communication with an interface server, which provides site owners/operators access to data and analyses on the various monitored sites. In some examples, data analysis facilities carry out analysis only, with data storage being consolidated into a single data storage facility that is in communication with the interface server.
