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.
