A Python library for DLMS/COSEM

Project description

dlms-cosem

A Python library for DLMS/COSEM.

We are developing this library as an ongoing project to support DLMS/COSEM in our AMR (Automatic Meter Reading) system Utilitarian.

As of now we support:

  • Receiving DataNotification via UDP.

Future Work:

  • GET, SET, ACTION over pre-established associations.
  • Interface classes implementation.
  • DLMS Client to handle communication.
  • GBT, ACCESS.
  • Establish Connections.
  • More Security options.

Tested with Italian Gas meters that are using a companion standard to DLMS. If you notice an error using the library please raise an issue.
