How to include a Python (pip) modules in OpenWRT image?

#1

Hi,
I am building customized image for the RaspberryPi 3, but I have no idea how to include e.g. the Python module paho-mqtt (https://pypi.org/project/paho-mqtt/) thats not listed in menuconfig.
Exists any further description or can somebody give some hints?

Thanks,
Nic
