How to get data from the DSMR smart energy meter to my Home Assistant VM

[JTech (Johannes)]

Hi,

SOLVED:

Using Slimmelezer+ to read data from energy meter Aidon 6534 with communication module 6442SE (swedish branschrekommendation)

Recently setup reading data from the energy meter Aidon 6534 with communication module 6442SE and thought I’d do a write up on the process as it was a bit tricky to solve for this specific meter, that follows the swedish standard HDLC-based “Branschrekommendation 1.2” I bought the hardware Slimmelezer+ But this does not initially support the format of the data from the Aidon meter. So after looking far and wide on the internet I found a forum where a guy, smarter than me, had solved specifica…

The question:
I suspect I already asked you this on the acutual slimmelezer+ site, but this might be a better forum actually.

I got a swedish HAN-port (RJ12) but that apparently uses the DLSM/COSEM (IEC 62056-21). (Also mentions HDLC/COSEM in the meter manual).

I connected the slimmelezer+ to the port and added it to WIFI and Home Assistant, but due to the protocol (I guess) i dont get any data.

Is there anything I can do to be able to use the slimmelezer device to get data, for this protocol, into HA? I’m no developer, rather rookie at this stuff, so if its complicated I will quickly run into issues =) But if there are some fairly straight forward guides/methods that others have used i could hopefully get it to work.
