Version 1.8
The example file above matches all water meters and doesn’t care about manufacturer or
version. The translation entry will map both m-bus values with internal keys:
"mbus.dib.volume.0.0.0.0.unmodifiedvalue" and "mbus.dib.0c13.unmodifiedvalue" to the same
OBIS object: 8.0.1.0.0.255. If a new meter is added with a different DIF/VIF combination for the
same value it could simply be supported by adding that new DIF/VIF to the list of “mbusKeys”.
5.3.4 Simplified mapping
Simplified mapping allows all data to be queried over DLMS without mapping meter specific M-
Bus keys (VIF/DIF combinations) to OBIS code.
There are two different ways to use simplified mapping:
1. Retrieving raw M-bus data.
2. Retrieving decoded M-bus data.
Raw M-bus data and decoded M-bus data can be retrieved over DLMS, by using the
corresponding keys in table 10. This is useful when using meters from multiple manufacturers.
