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.
The OpenMUC jDLMS library from Fraunhofer is used to implement the protocol. Please note that jDLMS is licensed under the GPLv3.
These devices can be used in combination with the Open Smart Grid Platform.
