Continuing the discussion from [Python Scripts for Additional Instruments](https://3dpaws.discourse.group/t/python-scripts-for-additional-instruments/46):

I’ve attempted to run the “rain.py 10” and one of the wind sensor files but I continue to get a “helper\_functions is undefined” NameError. Is there a missing function or is there some othere error in the code? I’ll double-check the installation procedure to make sure I’ve followed all the instructions for installation on my Raspberry Pi 4 model B.
