OK, now I´m a bit further…
I have left the settings all on default, like:
iec6205621meter:meter1.echoHandling=false
iec6205621meter:meter1.baudRateChangeDelay=0
After a restart of OH, I did a cat /dev/ttyUSB0 and saw that some data is comming in (the meter will only sends data when its getting a signal). So this means the binding can sucessfully communicate with the meter. After that, I started OH in debug mode to see whats coming in.It gave me the following:

So now I can be sure its basicly working! But unfourtunatly I dont get any data shown on my OH page. I created the item
Number gesamt “Zählerstand [%d kwh]” (gVerbrauch) { iec6205621meter=“meter1:1-0:1.8.0*255” }
but its not showing anything. Do I have to use an other OBIS code? Any suggestions?
