DLMS/COSEM

The open smart grid platform supports DLMS/COSEM (IEC 62056]. DLMS/COSEM is a popular protocol to read smart meters. DLMS/COSEM is the de facto standard in Europe.

The open smart grid platform DLMS/COSEM implementation was initial based on SMR5 and DSMR v4. Other types of meters/profiles can be added to the platform. The open smart grid platform implementation supports HLS3/4/5.

Protocol security

  • Public/private key pair(s)
  • Multiple encryption levels inside protocol (DSMR requires highest encryption level)
  • Full encryption of communication

Used library

The OpenMUC jDLMS library from Fraunhofer is used to implement the protocol. Please note that jDLMS is licensed under the GPLv3.
