Hey! I got the same issue, i solved it by using this:

{
	module: 'newsfeed',
	position: 'bottom_center',
	config: {
		feeds: [
			   {
			   title: "Expressen",
			   url: "http://expressen.se/rss/nyheter",
			   encoding: "ISO-8859-1",
			   },
		        ],
			showSourceTitle: true,
			showPublishDate: true,
			showDescription: true,
			reloadInterval: 200000,
			updateInterval: 15000,
			animationSpeed: 3500
                  }
}, 

When i was trying with Aftonbladet, DN and my local paper, they all worked without encoding, so there must be something in Expressens feed.

@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 :)

Couple of things…

Wind icons.
Ive tried copy weather-icons-wind.css to the vendor folder and change vendor.js with no luck.
I also tried to change getStyles: in the MMM-WunderGround.js file to use the ...-wind.cssfile located in the module folder.

Since its just the wind icons do i need to do anything special to use them?

How can i remove Sunrise/Sunset and mm (rain amount)
Im also wondering how to change the unit km/tim (km/h Swedish translate) to m/s?

As soon as i try to change anything to remove anything involved “Sunset” or “mm” everything breaks. I cant even remove /astronomy from getParams:. (Wich i believe is the wrong way to do it, But its better to try your way ahead then to hide in the corner.)

I want it to look more like this ->

I had no problems changing the default weather modules this way, but since im a newbie i cant figure this one out. :P

This happens to me to.
Using rPi 2 with latest Jessie, trying to make an fresh install of MM2 after i went total berserk and changed to much in config files and tried 3 party modules.
First try i followed instructions on Git, but it didnt help. Then i tried @KirAsh4 's Setup guide, got to npm start step, and was seeing an error message. Thought i was to hasty and missed something, so i did it again. I read and re-read all the steps before re-installing calmly and safe :) Then at npm start same thing happend.

EDIT:
Totally forgot that i was SSH:ing :/
DISPLAY=:0 nohup npm start & Worked like a charm!

Would be nice to edit the Setup guide with that ;)

Thank you Strawberry with everything.
I think i have to give this idea up tho. I have now been sitting for two days trying. But i just cant wrap my head around it. :/
Nothing makes sense for me with JavaScript. Not a single row of code have i been able to write.
Changing ‘fontColor’ is about my level of knowledge :P

I dont have any code. All this time i have been trying to understand what i am trying to do. If we look at The code from PIR-sensor, i dont know wich line are doing what. I have no clue on how and where to start. I cant see to understand The “building” of a module. All The “this. File” and what not dont make Any sense to me.
I need a How-to guide for toddlers :P

The python-button part is something i tried before, its the other language i have great difficulties with. (The one that MagicMirror is coded in.) since i dont understand The language, i cant read it and change/re-write what is needed for my idea to work. Ive been trying for 4h now.

Yeah… I have no idea what the heck i am doing^^,
This is way over my league.
Is there any good beginner guides for me? :p
I have been looking thru the PIR-Sensor module (and other) whilst reading the “Module Dev. Docu.” trying to understand.

Thank you Strawberry!
I will give it a go :)

Sorry if i put this post in the wrong category.

I have just started to fine-polish the last pieces in the config on my MagicMirror when my better half comes screaming " I want an whiteboard!"
Then the idea came to me that instead of making a mirror, i just use a ordinary glas and use it as an whiteboard. But i dont want it to have a white background all the time…

So my question is, is it doable by an physical button/switch to “invert” the colors on the hole layot ?

So that the handwritted “Whiteboard-text” is almost hidden when in “MagicMirror-Mode” (Original layot) and with the press of a button or switch the hole layout is inverting, making the background white and text black.

I have NO prior knowledge of programming, but i am not afraid to try. But i might need a push in the right direction first :P

My first idea involved a script like this:

´Push button´
Making it activate a script that replaces ´/css/main.css´ with ´/css/main2.css´ and thereafter sends a ´refresh´command.
Sort of…
( This is my programing abilities ;) )

Am i reaching for the stars here or is it something that is doable? Maybe there is another solution?
