DSMR tarif plan inverted values


I am reading the statistics from my Smart Electricity Meter (Belgium) via DSMR (DSMR Slimme Meter - Home Assistant).

But I noticed something strange: during normal hours the tarif plan shows low, and during low hours it shows as normal.

Any idea on how this might come? And how I could make those statuses more readable as well?

Found the solution in the Source Code of the integration on Github.
In the Belgian Meters the values for normal and low tarif mode are indeed inverted.

So in your configuration.yaml you have to set the version to 5B instead of 5!

  - platform: dsmr
    port: /dev/ttyUSB0
    dsmr_version: 5B

Thanks for that…
Had to modify this value directly in


as this parameter is not available through the UI
The 5B value worked way better…

It’s set in the configuration.yaml for me.
So in the front end you can set it via the File Editor.
