Huummm......more or less. I'm confused because I can see some stations in WeatherUnderground with frequently update time (30 seconds +-), but I'm now sure how to do this. My loop interval is set to 5 seconds (which is the time that my C program updates TXT file for FileParer driver) and I would like to update services for 30 or 60 seconds, but I know that WeeWx just update services (and report page) when does Archiving, whih is, by default, 300 seconds. So, my question is: there is any way to update services more often and keep archiving with 300 seconds? My Loop is already set to 5 seconds and my driver can fetch new data every 5 seconds.
