DLMS/COSEM Smart Metering Protocol

Implementing the DLMS/COSEM protocol stack on STM32 for Advanced Metering Infrastructure, including HES, DCU, and MDM integration with STS/CTS prepaid token systems.

Utility metering must be standards-compliant, secure, and scalable from a single meter to a national head-end — a demanding combination of correctness, security, and footprint on constrained hardware.

• A DLMS/COSEM stack on STM32 meter firmware
• STS/CTS prepaid token support
• Integration with DCU, HES, and MDM for end-to-end data flow

Add to confirm: deployment scale and communication media. Direction: security analysis of AMI messaging and tamper-evidence for prepaid metering.
