Loop interval is off

[Ron Walker]

Hi All,

I running WeeWX 3.9.1 on A Raspberry Pi 3 B+.  I have set a loop interval in the weewx.conf of 10 seconds, but looking at the incoming loop records the interval appears to be 28-30 seconds.  Is there a setting somewhere else that would affect this?

weewx.conf setting:

[FileParse]

    poll_interval = 10

    path = /var/tmp/data.csv

    driver = user.fileparse

    loop_interval = 10

loop data:

The only thing I can think of is that your system is taking an unusually long time to open the file being parsed. Try this version of fileparse.py. It will log the time the file is opened and closed, giving us a clue.

Even before loading the new version, I looked at the data file.  It was at 57mb.  I renamed the file to sart a new data input file and the loop interval returned to normal.  Thank you.

I have a forum etiquette question.  I have two more questions unrelated to this one.  Should I open a new thread for each one?

Thanks again!

[Thomas Keffer]

I can imagine it would take a little time to open a 57 MB file!

Open a new thread. It makes it easier for people in the future who might be searching for a similar topic.
