DSMR 5, double gas meter not working

[MariekevdAkker]

The problem

Hello, My active gas meter is connected to mbus2, however I do not get it to work. When I set my DSMR version to 5 I see a constant value of 0,11m3, which corresponds to the first mbus value. When I set my DSMR version to 5B it creates 2 gas meter entities: mbus1 and mbus2. However both show unknown. Do I understand it correctly that multiple mbussus is only supported for DSMR version 5B?

See below for a telegram, the second value of 06990.193*m3 is my actual gasmeter.

Only for 5B indeed. I'll try to merge and release dsmr_parser with the following PR (https://github.com/ndokter/dsmr_parser/pull/142) included the coming days and then prepare a PR for HA in the next coming weeks!

Same issue here. @dupondje do you have an update?

@dupondje Be mindfull of this issue, this code 0-2:96.1.0(xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx) 0-2:24.2.1(231023204000S)(06990.193*m3) is not always a double gas meter.

in my situation 0-2:24.2.1 is in fact a Water meter instead of a second gas meter.

the DSMR integration should give you the option to choose if sensor 0 is elec, sensor 1 is Gas or Water, sensor 2 is Gas or Water, ....

in case of double gas meter and water meter, there will even be a 0-3:24.2.1 ....
