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
Hi Daniel, thanks for your hints, I’m away for some days, as soon as I can reach the Rpi I try to che the code again and I’ll let you! Thanks a lot Marco

Do you have any idea why is not working...I guess is locale setting... Thanks Marco
