Add a line to the sys/file, right after info, that says the following: 'launch' : [ '/usr/bin/python', 'simple_stream.py' ], This way, when you send the payload 'launch' (without quotes) to the topic sys/file, it will execute the desired python script. Please adjust with the path of your python executable (in linux: 'which python' will tell you the path). Hope this helps.
