Dear Community,
I have a USB controlled relay setup. It is responding to hex commands, I’ve tested and is working fine from the shell, I just can not get it work with exec.
Here is my simple rule:
rule “Turn the light on”
when
Item Living_Room received command ON
then
val result=executeCommandLine(“echo -en ‘\xA0\x01\x01\xA2’ > /dev/ttyUSB0”, 1000)
logInfo(“exectest”, “Command line result: {}”, result)
end
I have run it with and without debug logging:

2020-04-28 23:09:25.897 [INFO ] [lipse.smarthome.io.net.exec.ExecUtil] - executed commandLine ‘echo -en ‘\xA0\x01\x01\xA2’ > /dev/ttyUSB0’

Based on the characters before > /dev/ttyUSB0 I suppose it is some kind of syntax error.
Do you have any suggestions for it?
Thank you in advance!
