MicroEJ DLMS Software Library for Smart Meters

Bring DLMS/COSEM Connectivity to Smart Meters

Smart meters must communicate securely and reliably with utility systems.
DLMS/COSEM (IEC 62056) is the global standard for smart metering communication.

MicroEJ offers a DLMS/COSEM software library based on the proven implementation from Kalkitech.
It enables manufacturers to integrate DLMS/COSEM quickly on smart meters without building the protocol from scratch.

The software library supports client and server roles and is designed to run on constrained devices as well as more powerful platforms.

 

Why Choose MicroEJ DLMS Software Library for Smart Meters?

With MicroEJ DLMS/COSEM software library, smart metering manufacturers can:

  • Implement DLMS/COSEM (IEC 62056) using a field-proven protocol stack
  • Reduce development risk with a DLMS UA-attested implementation
  • Support client and server applications across the metering chain
  • Accelerate time to market with ready-to-integrate protocol libraries
  • Ensure interoperability with utility head-end systems

Result: reliable DLMS/COSEM communication, faster certification paths, and predictable integration for smart metering platforms.
