Weatherunderground - currently - hourly - daily - configurable

Your api-url would be this:

http://api.wunderground.com/api//conditions/forecast10day/astronomy/alerts/lang:NL/q/pws:IBATTLE3.json

pws stands for personal weather station.

Did you set your locale correctly in config.js? The sunset time for the wunderground module comes from the weatherunderground api so reflects the time at the weatherstation location.

The loctype thing is a bit of a mystery. I copied it of a wunderground generated url. Not entirely sure what it’s for. You could just leave it out i think.

@Snoevit When you remove /astronomy you just modify the api call. The script still tries to place the (now absent) information on the screen. Leave the api call in tact and modify the refresh_dom function in the script. Also further down there’s a windspeedconversion which you could try to modify.

@RedNax
Thx for your reply! I forgot to update my post to tell you that i found how to remove the ‘rain-part’ :P But thanx for the note on the windspeedconversion!
Oh, a also figured out my problems with the icons. i replaced the files in the vendors folder, exept for weather-icons.css. I thought those two files were the same, until i saw them side-by-side :)

@RedNax , sorry for the delay, I’ve had company and then had to wait for an alert message. My config doesn’t have the alerttruncatestring even in it. I’ve copied both the results of the Wunderground alert and the text from the NWS. I wonder if it’s dying at the /u00A , which appears to line up perfectly with a CR/LF from the NWS text. It’s also the first item in the message, which could explain why I don’t see any text other than the description.

@Shockwave Well, it would seem WU is rather ‘loose’ with it’s API implementation…

In your payload the full warning is in the message property. The Wunderground module expects is in the description property (only based on my observation of a single payload by my local station :S ). Ties in with your observation, which is always nice :)

Watch this space for a fix…

UPDATE: fix implemented… The module examines description and message lengths and uses the longest one… Have a go! :)

@RedNax It works! Thanks for fixing that so fast. Now I need to politely bug MichMich about the size of the alert box since our weather service is so verbose. :)

@RedNax

That’s a handy test - Many thanks.
When I request:
http://api.wunderground.com/api/[my key]/conditions/forecast10day/astronomy/alerts/lang:EN/q/pws:IBATTLE3.json

I get a full set of data back.
The module is still getting stuck on ‘Loading’ on the mirror though.
My config is:

{
    module: 'MMM-WunderGround',
    position: 'top_right',
    config:  {
            apikey: '[my key]',
            pws: 'IBATTLE3;loctype:1',
            lang: 'EN',
            fctext: '1',
            fcdaycount: "5",
            fcdaystart: "0",
            hourly: '1',
            hourlyinterval: "3",
            hourlycount: "2",
            alerttime: 10000,
            alerttruncatestring: "english:"
    }
},

Can you see anything wrong there please?

Thank you.

@RedNax

This may explain the issue to you hopefully. I thought I’d given you this info before, but it seems not.

In the console I get an error:
MMM-WunderGround.js:407 Uncaught TypeError: Cannot read property 'length' of undefined

The relevant code is:

	processWeather: function(data) {
		this.alerttext = "";
		this.alertmsg = "";
		for (var i = 0, count = data.alerts.length; i < count; i++) {

Any idea why the array would be undefined?

Many thanks.

@Pauliolio The issue is with the config. try the following change:

pws: 'pws:IBATTLE3',

Hi @RedNax,
thanks for the excellent module! I seem to have some difficulty having night time icons displayed. I’m not sure what I’m doing wrong as this is what my module looks like at 1 am in the morning:

Using the API in my browser window I get the following two lines:

“icon”:“clear”,
“icon_url”:“http://icons.wxug.com/i/c/k/nt_clear.gif”

It seems to me that I’m getting the daytime “clear” condition icon, maybe due to the ambiguous icon declaration, anything I can do to change icons like this one to nighttime icons?
