FR: Support for IR port Kamstrup meter(s) with simple authentication #389

Closed bipsendk closed 1 year ago

bipsendk commented 1 year ago

Is your feature request related to a problem? Please describe. Apparently no support for DLMS/COSEM meter with simple authentication via serial/IR Port

Describe the solution you'd like Support for meters with IR port (through serial port), where simple authentication is being used - e.g. Kamstrup 382Lx7

Describe alternatives you've considered Using Gurux software on Raspberry Pi, but this will require quite an amount of programming to feed data into HA via MQTT

Additional context Protocol description attached - IR port specs/auth/client/server addresses is listed at page 14 55121424_D1_GB.pdf DLMS generation M N1.pdf

Duplication, see this thread: https://github.com/gskjold/AmsToMqttBridge/issues/126 Requires Kamstrup-proprietary protocol, only seen partially documented on various personal implementations.

Duplication, see this thread: #126

Are we sure this is the same? When I look at the document document, this is standard IEC62056-7-5, but with two-way communication.

I see now that this document is also referenced in the other thread. I think I may have seen this document before, but it's hard to keep track these days.

Sorry - my mistake. I meant this thread: https://github.com/gskjold/AmsToMqttBridge/issues/373

My opinion is that reading "IR eye" / optical port is outside the scope of this firmware, as I consider those meters to be obsolete. They will surely be replaced by AMS meters at some point of time.
