DSMR slimme meter intergration with new Sagemcom XT211 problem

[jacoch]

The problem

Hi,

My previous device was a Sagemcom T211 and was working fine for a long time. It has been replaced by the new XT211. Since then, I'm unable to configure the integration. If I use the same 5B version, it just times out when adding it. The only version that is working is 5S that seems to do less validations on setup. But a lot of data is missing. I've included the log that shows some errors and telegrams while trying to add that device.

Is there any chance to make that version be readable by DSMR slimme meter? Or is there another way to setup that device? Thanks

I've been in touch with my electricity provider and he confirmed that Sagemcom made a mistake in the current firmware. They will fix this in a futur update at end of the year. In the meantime, what do you recommend to fix this? Is there a way I can reformat the data between the counter and HA? Here is a table with the errors (the second column is the sent code and the last one it's the expected code):

By looking at HA log, I notice that another entry has a problem. I indeed see that this line is sent:

0-0:98.1.0(2)

It seems incomplete. I tried to modify parsers.py to fix that error and accept the wrong entries, but it wasn't successful. It seems something else is causing an issue.

After comparing more in detail the data received and the expected data, I've notice that another line is wrong. It's that one:

0-0:0.0.0(123456789012)

I replaced my real id. It should indeed be

0-0:96.1.1(123456789012)

After modifying the parser to read equipment id from that value and ignore the line 0-0:98.1.1 that is incomplete, I've been able to setup DSMR slimme meter again. It's a temporary fix that need to be applied on each reboot of my NAS, but at least it works in the meantime. I've returned this information to our electricity provider so that it can ask Sagemcom to fix this in a future update.
