Keyerror: 'time' about opc-n3_python

[JarvisSan22]

Hi Marco
Sorry I have not tested the rpi3 interface with an OPCN3 as I no longer have access to an OPCN3
and the server code was designed for the my SDS011 directory and I just copied it other to the OPCN3 with some changes in the code, thinking it should work fine.

So I am thankful that you are trying to use, so we can actually get it working.
I have two ideas of what it could be.
1)Can you check your data files, that they have the "time" column if it's not spelt as "Time".
2)It could also be an issue with line 36 in interface.py
dataloop = pd.read_csv(file, header=4, error_bad_lines=False, engine='python',index_col=False)
The header may not be number 4, so its could be cutting data header column.

Kind regards
Daniel Jarvis
