Conky Weather Forecast Python Script

[kaivalagi]

Now i am having an issue with the wind direction arrows (see screenshot).

${execi 3600 python conky/conkyForecast.py --location=BEXX0008 --datatype=WD}

needs to become

${execi 3600 python conky/conkyForecast.py --location=BEXX0008 --datatype=BF}

wind direction will return in the form SSW or NE etc, so is not suitable for use with a custom font. You'll end up with multiple characters and square boxes here and there. BF converts wind direction toa single character mapped to the arrows font.

The details of the BF datatype were mentioned in dev history, and in the previous thread posts when the dev was done, but were missing from the usage help, I've updated the first post to include a small mention...

You should be home and dry now

Please post your final screenshot and conkyrc when you're happy, it should help others in need of a good example!

Cheers

ok thanks, that should do it.

I will for sure post a screenshot along with the codes when it is finished.

In the mean time, i still have a few questions:
-the weather.com 10-day forecast is probably not included in the feed?
-What exactly is "night output" (--night)
-Is it compatible with the other weather fonts that are available on the net?

Thanks!

Hi Matt

1. No, for the forecast there is only 5 days, today and the next four, so you can use: startday=0 - for today up to startday=4 for the 5th day.

2. You can have a "double" output for each day, if you use --night it will switch output to night data, if omitted day output will be output. weather.com switches to the night time data output around 6pm. I don't bother, I sleep at night.

3. Maybe, but I don't think so. As the script calls the font by "location" if another font has the same type of symbols in the same location yes, but chances of that happening are probably not good.

For example: lets say the font here has the sunny symbol a "B" but another font has it at "S" and you use the other font, the script will call for "B" and that might be: Thunderstorm.

Hope this helps.

ok, thanks, and what exactly is meant by "night output"? What will be different then? Sorry but i dont have a clue of what to expect from it.

thanks!

Hi again...

To be absolutely honest I'm not sure. For me a forecast covers the 24 hours. Like I said I don't use the -night command and my conky shows the forecast fine.

Guess I'll do a test weather conky with two identical sets of lines except the second set will have a -night option in it and see what's what.

I'll be back.

PS: Anyone else care to explain what's what here I'm listening too!

The night option displays data in the night section of the forecast data from the xoap weather feed, the only way to really explain this is to show you the data returned from the site. You can see below the 2 sections of forecast xml, <part p="d"> starts the day time data, <part p="n"> starts the night time data. As you can see the temperature doesn't fit into the day or night section and is general data for the whole 24hr period.

    <day d="1" t="Tuesday" dt="Jul 29">
      <hi>24</hi>
      <low>14</low>
      <sunr>5:10 AM</sunr>
      <suns>8:52 PM</suns>
      <part p="d">
        <icon>30</icon>
        <t>Partly Cloudy</t>
        <wind>
          <s>24</s>
          <gust>N/A</gust>
          <d>192</d>
          <t>SSW</t>
        </wind>
        <bt>P Cloudy</bt>
        <ppcp>20</ppcp>
        <hmid>65</hmid>
      </part>
      <part p="n">
        <icon>29</icon>
        <t>Partly Cloudy</t>
        <wind>
          <s>24</s>
          <gust>N/A</gust>
          <d>195</d>
          <t>SSW</t>
        </wind>
        <bt>P Cloudy</bt>
        <ppcp>20</ppcp>
        <hmid>76</hmid>
      </part>
    </day>

So I think the datatypes that can differ between night and day are:

• WF
• CC
• CT
• PC
• WD
• WS
• WG
• HM

Thanks for all the good questions, makes for a better solution. I'll be updating the help details to suit when you've got all the answers you need

thanks, i think i will try it once, to fully understand and maybe make use of it.

Well if you want more questions:
-can the wind speed be displayed in beaufort?
-can de sunrise/set time be in 24H format?

Thanks once again. It is nice to have a contribtution with such a level of support!

Never come across "beaufont", tell us the conversion formula to get to it from m/s or mph etc and I'll add a --beaufort option which will convert speed output

For the 24hr time would it be a good idea to base time on the system locale setting for time format? I've already figured that stuff out for my google calendar script. It would mean it is displayed based on any one system's setup, rather than directly through script arguments.

We are all happy to help here, enough people have helped us over the course of time...

beaufort ... OH that will be fun: Beaufort scale

24 hours format!!! What a genius. Why didn't I think of that.
{alter ego; you just answered that dummy: genius}

Formula in the above link, have fun. Not a sea going type here but will be nice to see.

OK, I'm waiting for the 24 hours stuff now too! (Thanks Matt!)

CHIMO!

[kaivalagi]

can the wind speed be displayed in beaufort?

beaufort ... OH that will be fun: Beaufort scale

Should have known to go to wikipedia!

Here goes...

V = 0.836 x B^(3/2) m/s
V = 0.836 x B^(3/2) x 3.6 kph
B = (1.196172249 x (V x 0.278)) ^(2/3)

That would make 20kph = 3.53 => 4 B ... sounds about right?

I suppose it needs to be rounded up to the nearest whole number? Worse case on the scale then...

Edit: In python that would be:

beaufont=str(int(math.ceil(math.pow(float(windspeedkph)*0.332270069, 2.0/3.0))))
