DSMR Slimme Meter integration to deal with decryption for Luxembourgish meters (and maybe other countries such as Austria)

alexboss · June 28, 2022, 3:22pm

Some Smart Meters require decryption (Luxembourg, I’ve heard Austria as well, maybe Sweden too?).

Unfortunately, DSMR integration does not offer to provide the decryption key to read the metrics.

Even though the version 5L is available, it’s somehow useless since the stream to read is encrypted.

It has been requested here: DSMR Slimme Meter integration v5L for Luxembourgish meters seems to not work · Issue #66802 · home-assistant/core · GitHub

And also expressed by Marcel Zuidwijk for the P1 readers (ethernet) - see P1 reader ethernet – Marcel Zuidwijk

Thank you and best regards.

Hi, I second this request as it’s pretty frustrating to buy the hardware after checking the DSMR integration page that make you thing that this has been tested on Luxembourgish meters to finally discover that it is not compatible.

That would be really great - tried for hours to get a solution - nothing until yet

DSMR ESPHome component does provide a decryption option.
