Attached a file with logs of several identifiers configurations: [Logs with several identifiers.txt](https://github.com/volkszaehler/vzlogger/files/3811403/Logs.with.several.identifiers.txt) I can hopefully support the test.

The only difference to my service definition is the ExecStart command. Try `ExecStart = modbus-proxy -c ./usr/lib/mproxy-conf.yaml` I guess it's only the missing dot before the slash.
