Thanks very much for your reply with the streamlined version!
To be honest, I now had to settle for calling the actions like this
var command="echo 'b8:27:eb:b7:29:4a mixer volume -2' | nc -q0 192.168.1.2 9090" mcApi.osCommandExecuter().executeLinuxCommand(command);Meaning, the command get's "netcat'ed" to the server - is there just by chance a comparable API call as well?
Thanks again very much for your work,
Joost
