Hello @basvdlei I'd like to use your DSMR parser implementation as part of evcc-io/evcc#3284. According to the BSD license it seems as if this would require your approval. I'd appreciate if it could be given?

One small suggestion to simplify the usage of the code as library would be to provide a

DataObject.FloatValue() (float64, error)

method that should parse the value string and handle units to return derived base unit (i.e. multiply/divide by 1e3).

Is your feature request related to a problem? Please describe.
The DSMR parser currently seems to

• require CRCs
• assumes "kW" only (i.e. ignores "W" units) and
• stumbles over "*255" suffix to the OBIS code

Telegrams like this don't work:

 /ESY5Q3DB1024 V3.04

1-0:0.0.0*255(0272031312565)
1-0:1.8.0*255(00066982.7369255*kWh)
1-0:2.8.0*255(00025261.5976087*kWh)
1-0:21.7.0*255(000210.92*W)
1-0:41.7.0*255(000225.08*W)
1-0:61.7.0*255(000144.75*W)
1-0:1.7.0*255(000580.75*W)
1-0:96.5.5*255(80)
0-0:96.1.255*255(1ESY1313002565)
!

Describe the solution you'd like

• Parse units w/o kilo correctly
• Accept CRC-less telegrams
• Accept "*255" suffix to the OBIS codes

Describe alternatives you've considered
My current workaround is parsing above telegrams and re-assembiling them in evcc-dsmr
The workaround can be found here: https://github.com/Aeroid/dsmr-tools as a python tcp bridge. It also includes a few more dumped telegrams.

Hi, is there any documentation on how to run this or package it in Docker?
