@msteigenberger: Thanks for your answer. I use a Easymeter Q3D from Volkszähler. It won’t works with and without pull sequence. But today, after ~10 more tries it works, i got the reading in OH2 
. Don’t know exactly what my mistake was, maybe old entrys in the vzlogger.log. Does the binding reads this file? Today i delete this file and restart the meter script.
Thanks for this great binding!
