Until now I have executed Python scripts using an exec node in this way:
python -u /home/pi/....../script.py
and everything works great.
I have a situation now where I need to execute a Python2 script with a payload. In terminal I execute it in this way and it works fine: python2 ./sendsigfox1.py 123abc
The script send the message 123abc on sigfox uplink.
How can I do that with a nodered exec node passing the payload (123abc ) as an argument to the script?
I would appreciate some help. Being an hobbyist,..... at time is difficult.
