Unrecognized VIF extension: 0x01

[maherma-adg]

Using a Engelmann SensoStar 2C we get a Unrecognized VIF extension: 0x01 from measures corresponding to energy in MWh
Tracing VIFE decoding routine, I think there is an error in this function because don't cover al cases defined on 8.4.4 section of MBus spec.

Hi maherma-adg,

thank you for notice. libmbus can handle the Engelmann SensoStar 2C with the M-Bus decoding from mbus-protocol-aux (normalized). Unfortunately the example binaries in the bin directory still using the old decoding function. I plan to fix this in future.

In the case you only need decoding of the hex file, please look in the test directory. The program mbus_parse_hex supports the improved M-Bus decoding:

mbus_parse_hex -n test-frames/sensostar2c.hex

Hi lategoodbye,
Units isn't problem because our application is monitoring values and didn't use units.
Thank you, Manuel.
