Weewx-rain24h addon

[kufuu]

I installed the weewx-rain24h add on and was wondering how to get he 24hr rain totals to display on the season skin desktop ?

You might have to help us out here, what or where is the 'weewx-rain24h add on'. My quick google failed to find such an extension.

No need for an addon.  Just use

$span($day_delta=1).rain.sum

to return the last 24h rainfall total.

You can see it on my weather site at weather.cusick.org.uk

Seems a bit of a roundabout way to provide data that’s already easily available - presumably retrieving the 24h rain sum from the database, then injecting it back into the loop packets.  I’m obviously missing something.

Thanks geoff, I like that, just where do I put the  "$span($day_delta=1).rain.sum" , sorry but Ive only been messing with weewx for only about 6months.

I wrote this extension; although, I no longer use it because I have generalized the functionality to work on any observation and for any time length in my weewx-loopdata extension.

What you are missing is that the plug-in operates at the loop packet level.  Other than loading from the database at start up, with archive interval precision, it does not read the database.  Rather, it keeps track of any rain recorded in loop packets such that they can be decremented from rain 24 hours later.  For example, if .01 rain occurs 87s into an archive interval; and another .01 rain occurs 20s later; the 24 hour rain will decrement (i.e., the rain24 value injected into the loop packets) when each .01 occurrence falls out of the 24 hour window; not when the archive record in the database is older than 24 hours.

Of course, this is all meaningless if you are just going to use it in reports that are only generated on the archive interval; but the for insane (I resemble that remark) who want to see 24 hour rain decrement at loop interval precision on their weather sites that update on every loop packet, it is useful.

In the skins folder (something like /etc/weewx/skins), you’ll find a number of files called <xxxx>.html.tmpl. These are template files for the html pages that weewx generates.   Edit the file for the page where you want to place the 24h rain figure.  You’ll need to understand its structure to decide where you need to add some lines.  My site uses the Bootstrap skin, which uses a file gauges.html.tmpl to create a page containing some gauges and some text, including a table of values where I’ve put the 24h rain figure.  The relevant section of the file looks like this:

<!-- Station info -->

          <div class="row">

            <table class="table table-hover">

              <tbody>

                      <tr>

                        <td>$Labels.Generic.rainRate</td>

                        <td>$current.rainRate</td>

                      </tr>

                      <tr>

                        <td>24h Max Rate </td>

                        <td>$span($day_delta=1).rainRate.max</td>

                      </tr>

                      <tr>

                        <td>$Labels.Generic.dayrain</td>

                        <td>$span($day_delta=1).rain.sum</td>

                      </tr>

                      <tr>

                        <td>$Labels.Generic.windchill</td>

                        <td>$current.windchill</td>

                      </tr>

            </tbody>

            </table>  

          </div>

Take a look at weather.cusick.org.uk to see how it looks in practice.

So you’re maintaining a circular buffer of (24h/loop packet interval) rainfall samples.  Is that right?

I installed this extension not knowing when I should have just came here and asked, oh well !!  Thanks u guys for all your help

[John Kline]

There is no need to use all that space when most loop packets will have zero rain.

I just record the rainfall (non-zero rain in a loop packet) as a list of debits.  On each loop packet, I look at the top of the list to see if any have matured (24 hours later).  If so, I decrement rainfall by the amount in the entry and delete that entry.

Im using the default " Season Skin", not finding a html.tmpl file with that structure.

[Geoff Cusick]

Sorry, I’m not familiar with the Seasons skin, but a quick look shows a set of .html.tmpl files under /etc/weewx/skins/Seasons.  The ‘home’ page is index.html.tmpl, and there’s a ‘footnote’ section that contains text.  As a quick try-on, you could insert the 24h rain total there.

Have fun

Now I have the rain 24hr totals where I want it, had to put it in the Current.inc folder at the end.
