Archive interval confusion - is there a way to force archive interval?

[Robin Wilson]

Hi,

I've got weewx connected to a FineOffsetUSB sensor, a WS2080.

I've set the archive_interval in the config file to 300 seconds (5 minutes). However, looking at the graphs in the generated HTML pages, I only see entries every half an hour (see image at the bottom - I'm using the weewx-wdc skin). The config file warns that if the sensor can do data logging itself then that interval will override the archive_interval set here, so I wonder if that's what happening here.

I've run `sudo weectl device --set-interval=5` to set the interval for the device itself to 5 minutes, and when I run the command again it says the current interval is 5 minutes - but I don't know whether that has actually taken effect properly.

Is there a way to determine what archive interval is actually being used? Or is there another setting to configure the data points used for the display graphs?

Thanks,

Robin

If you run weewxd from the command line, it will print out the LOOP packets and archive records. You can see the timestamps and exactly what's in them. The records are marked with "REC".

Hi Robin,

It's look like your are using the weewx-wdc skin.  

By default, the wdc skin is using an aggregation interval of 30 minutes for the  "day" graphs.  You will have to change the settings in the skin.conf file :

[DisplayOptions]

...

... 

[[diagrams]]

...

...

...# Set which diagrams you want to see on the day, week month, etc pages.
        # Note for alltime: if aggregate_interval is not set,
        # it will be calculated automatically based on the number of days/records.
        [[[day]]]
            aggregate_interval = 1800 # 30 minutes

            ...

...

...

Try to change to 

             aggregate_interval = 300 # 5 minutes
