ESPHome DSMR Slimmelezer sends strange data

That last bit about the component taking too long is a mere warning. That wouldn’t stop the device from sending data.

Looking at the config you posted earlier, I don’t see any sensors that makes use of dsmr.

There’s also no need to use the external component. There are no features in dev that aren’t in the stable release. Better drop that part therefore.

Hi,
yes, I did forget to add sensors.
Now some sensor values are found, some are not supported.
I’m a lot happier than two days ago :slight_smile:
I also closed related #2891 with a comment about the fix.

Do you think a feature is possible to refer to OBIS codes alternatively like

sensor:
  - platform: dsmr
    obis_01:
      code: '1-0:32.7.0'
      name: 'Voltage Phase 1'

Sensor could be obis_01 … obis_50 to support region specific data and next DSMR standards.

I am currently working on a refactor of the DSMR component, and the main target is to implement a DSMR parser for ESPHome, to get rid of the dependency on the Arduino parser. With that parser in place, it will be a lot easier to implement missing OBIS codes, since it will then be a one step implementation that can directly be tested.

Implementing a custom OBIS code would require more configuration than you proposed here. Not all lines are formatted in the same way for example, and units need to be specified. But it’s a nice idea to be able to specify missing OBIS codes like this. Ideally though, I’d like to see these codes implemented so all users can benefit from them.

I’m looking forward to the update. Until then I’ll build your D1 mini based P1 logger just for fun, because parts are on the way already :slight_smile:

Thanks again Jos and Maurice for your help, I’ll close this topic now and start to make beautiful power graphs.

If somebody finds this: partial solution for Hungarian DSMR with long text message can be found in issue #2891.

Hi,

I have a similar issue when trying to read the smart meter. I have created a topic here: DSMR topic

Do you have any tips to solve this?
