hi,
i am the author of the old binding in openhab 1.x
i was not able to finish the migration to openhab 2.x as i wanted to us also the new openmuc library.
in the meantime there is a new smartmeter binding for OH2.
I do have issue with that binding as my landis gyr meter E350 is not working with openmuc 2.1.0
have you been able to use the new smart meter binding.
i am currently looking into the issue on the openmuc 2.1.0 not reading my data. in the meantime i am getting data. So updating the fixed openmuc to the smart meter bing may help
