rain rate graph

[Russell Harris]

A few weeks ago, we had rain which my Davis Vantage Pro2 reported falling at over seven inches per hour, but after a five or ten minutes the rate subsided to a much lower rate.

Regrettably, the Vantage Pro2 does not record rain rates, but merely reports the instantaneous value.  It would be nice for weewx to report rain rate in the same manner (graphical) as wind speed or temperature is reported.

It's all there. Simply configure your WeeWX installation to do so. How? That depends very much on your particular installation.

I am afraid that the project is beyond my programming ability.   Perhaps I could pay someone to do the work.

My installation has no modification; it is a Davis Vantage Pro2 with the old LCD console and USB-interface data logger.

You can solve this without programming anything, simply by configuration. And of course you modified your installation, at least by entering values during the installation, when prompted.

The customization you would like to do requires manual actions, editing a Section of the "Seasons" skin. 

A first read: https://weewx.com/docs/5.1/custom/custom-reports/

For your needs it boils down to adding and enabling a plot for rainRate for day/week/month/year, which is not predefined in skin.conf of "Seasons".

I thank you for the encouragement and reference, Michael.  I shall give it a try.  (Perhaps my motivation is vanity, so that I can boast, "It rained harder at my place than it did at yours.")

I am pretty confident that someone here is having a rainRate plot generated, using the "Season" skin and can provide a configuration snippet. If not, I can do this some time later this week. Until then, reading the referenced docs should enable you placing the snippet into the right position.

I shall be watching!  

This month I replaced all the Davis electronics (except the console), after hours of troubleshooting with Davis Support failed to isolate the problem.  The refurbished Davis system has been running for a week now, and I cannot help but be a bit paranoid.  However, the recent outage is the only one in six or seven years of service.  In addition to the ISS, the system has a Sensor Transmitter for the wind station (at 33 foot elevation) and a Repeater.  

Meanwhile,  my weather website has been idle, and I changed hosting service.  So I decided this was a good time to upgrade from weewx 4 to weewx 5. 

Again, thanks.

To add a plot for the rain rate, in your weewx.conf, add to the existing "StdReport/SeasonsReport" (The grey colored parts should already exist, add the black bold parts)

[StdReport]
   
    [[SeasonsReport]]
        # The SeasonsReport uses the 'Seasons' skin, which contains the
        # images, templates and plots for the report.
        skin = Seasons
        enable = true
        HTML_ROOT = /var/www/html/weewx5/seasons
        
        [[[DisplayOptions]]]
            plot_groups = barometer, tempdew, tempfeel, hum, wind, winddir, windvec, rain, rainRate, ET, UV, radiation, lightning, tempin, humin, tempext, humext, tempext2, humext2, templeaf, wetleaf, tempsoil, moistsoil, pm

        [[[ImageGenerator]]]
            [[[[day_images]]]]
                    [[[[[[rainRate]]]]]]

            [[[[week_images]]]]

                [[[[[weekrainRate]]]]]

                    [[[[[[rainRate]]]]]]

            [[[[month_images]]]]

                [[[[[monthrainRate]]]]]

                    [[[[[[rainRate]]]]]]

                   

            [[[[year_images]]]]

                [[[[[yearrainRate]]]]]

                    [[[[[[rainRate]]]]]]

Michael, Problems!

In weewx.conf for weewx 5.1.0, under [[SeasonsReport]] there is no line:

HTML_ROOT = /var/www/html/weewx5/seasons

But, earlier, under [StdReport] there is the line:

HTML_ROOT = /var/www/html/weewx

And from the status file, what is an exit of status=3 ?

That'S OK, don't care too much about the grey parts, they are only to illustrate, where to put the other stuff.

Status = 3 means you have a config error. I take from the error message that you've put the config snippet into a wrong location. The brackets [ ] represent the nesting depth of your configuration items. Dir you really put only the bold, black parts from above below [[SeasonsReport]]?

[Russell Harris]

Yes, except for a comment an the beginning and at the end; attached is
a section of weewx.conf .

Should I break up the plot_groups line?

Michael,

Here is your list of plot_groups:

plot_groups = barometer, tempdew, tempfeel, hum, wind, winddir,
windvec, rain, rainRate, ET, UV, radiation, lightning, tempin, humin,
tempext, humext, tempext2, humext2, templeaf, wetleaf, tempsoil,
moistsoil, pm

But my installation of weewx shows only the following graphs:

barometer, tempdew, tempfeel, hum, wind, winddir, windvec, rain, ET,
tempin, humin

Is that what is causing the error?

My previous Post got deleted, sometimes Google Groups acts weird. Retry:

I made a mistake although I tested the config locally, above, I pasted the config with a missing line. It shouuld looks like this:

# BEGIN Rain Rate

        [[[DisplayOptions]]]
            plot_groups = barometer, tempdew, tempfeel, hum, wind, winddir, windvec, rain, rainRate, ET, UV, radiation, lightning, tempin, humin, tempext, humext, tempext2, humext2, templeaf, wetleaf, tempsoil, moistsoil, pm

        [[[ImageGenerator]]]
            [[[[day_images]]]]

                [[[[[dayrainRate]]]]]

                    [[[[[[rainRate]]]]]]

            [[[[week_images]]]]
                [[[[[weekrainRate]]]]]
                    [[[[[[rainRate]]]]]]

            [[[[month_images]]]]
                [[[[[monthrainRate]]]]]
                    [[[[[[rainRate]]]]]]
                   
            [[[[year_images]]]]
                [[[[[yearrainRate]]]]]
                    [[[[[[rainRate]]]]]]

# END Rain Rate

[Russell Harris]

And it works! Many thanks! And may the Lord bless you.
