Hi,

I added 3 files from two smart meters. One smart meter type is even new in your list.

The new one is parsed by libsml quite well, but the model you have already two other files makes problems:

cat ../../../Desktop/EMH_eHZ-HW8E2A5L0EK2P_2.bin | ./sml_server - 129-129:199.130.3255#EMH# 1-0:0.0.9255#06 45 4d 48 01 02 71 58 20 51 # 1-0:1.8.0255#13312484.9#Wh 1-0:1.8.1255#13312484.9#Wh 1-0:1.8.2255#0.0#Wh 1-0:15.7.0255#139.4#W 129-129:199.130.5*255#19 92 1a 52 65 64 ac ba e3 02 6e 61 35 26 75 ec 28 27 66 83 f0 2d bb 32 fa 70 1e 3a 75 3b 34 21 8b 64 66 b1 50 64 df 59 19 f9 f1 3f 84 b5 b2 c9 #

I do not know about the last output 129-129:199.130.5*255 Is this output correct? is the parser working well here? Maybe not.....

Hope my contribution helps a bit to make your great work even better!

Best regards

Wolfgang

i had a look at your problem.

you are right that the output may look weird from a first point of view, but i think it's quite correct - as obis-code 129-129:199.130.5*255 means "public key" of your smart meter, which is a 96 digits number

crazy! Thanks for your investigation! The data stream is 48 Bytes. So 96 nibbles does "digit" mean "nibble" in your answer?

yes
