Zusammenfassung:	The present subject matter is directed to methodologies, devices and systems for providing enhanced tamper detection in AMR/AMI systems. A consumption sensing meter has associated therewith an endpoint device. The endpoint device is configured to increment a tamper counter upon detection of various events including, such as, metrology and non-metrology programming events. A count of detected tamper events is conveyed to a head end device within the system is compared with a known count representing authorized programming events and an alarm is generated if the reported count and known count do not match.
