A method includes storing, at a head-end system, an indication of initial configuration parameters of a configurable resource meter. The method also includes requesting, by the head-end system, a report indicating updated configuration parameters from the configurable resource meter and receiving, at the head-end system, the report indicating the updated configuration parameters of the configurable resource meter. Additionally, the method includes comparing an indication of the updated configuration parameters to the indication of the initial configuration parameters. Further, the method includes determining a potential compromise of the configurable resource meter when the indication of the updated configuration parameters is different from the indication of the initial configuration parameters.

Automated tamper detection of meter configuration parameters

Certain aspects and features include a system and method for validating fundamental-only power measurements. A meter testing application calculates an expected registration for a meter under test by comparing a fundamental demand indicating an amount of power expected to be delivered by the fundamental component to a known load with a wideband demand indicating an amount of power expected to be delivered by the wideband voltage to the known load. The application further measures, from the meter under test, a measured registration by applying the wideband voltage component and the known load to the meter under test, which is configured to measure power consumption from the fundamental component only. The application calculates based on the expected registration and the measured registration, an error for the meter. When the error is outside a tolerance, the application identifies the meter under test as non-compliant.
