You shouldn’t need to run 'npm install' inside the module folder unless the author specifically told you to do that.

[acdacd2]

I did that,

Now it’s solved, I copied the .json in the right folder

[Eunanibus]

Awesome. @KirAsh4 is correct - The README has all the instructions so be sure to take a look.

Please let me know how it works cause you’ll be the first person to use it

[KirAsh4]

As a further explanation, 'npm install' is only required if the module you are installing requires other node modules to also be installed. When you first install MagicMirror you have to run 'npm install' to install all the dependencies for it to work, however generally, modules don’t need that. The exception is if someone writes a module that requires another node module that isn’t already installed. So there was no need to run that, nor to copy any '.json' package files anywhere.

[acdacd2]

is that correct ?

{
		module: 'MMM-HTTPRequestDisplay',
		position: 'bottom_bar',	// This can be any of the regions. Best results in left or right regions.
		header: 'MMM-HTTPRequestDisplay', // This is optional
		config: {
			accessToken: 'http://api.openweathermap.org/data/2.5/weather?q=London,uk&mode=xml',
			// See 'Configuration options' for more information.
		}
	},

Sorry, I made a lot of mistakes on the README it seems.

Instead of

accessToken : "http://etc"

use

httpRequestURL: "http://etc"

apologies

[acdacd2]

no problemo,

with this config, black screen

modules: [
	{
		module: 'MMM-HTTPRequestDisplay',
		position: 'bottom_bar',	// This can be any of the regions. Best results in left or right regions.
		header: 'MMM-HTTPRequestDisplay', // This is optional
		config: {
			httpRequestURL: 'http://192.168.1.248:8889/status.xml',
			// See 'Configuration options' for more information.
		}
	},

Make sure that you’re not just copy and pasting blindly into your config file.

After each

modules: [
{
etc
},

Note the comma , after the module. That comma should only be there if there are more modules.

Likewise, if you’re pasting it last, you need to make sure the module before it has one, to let the script know there are more modules after the previous one.

So the pattern is

modules: [
{
   module: ‘firstModule’,
   config: {
   option : ""
   }
}, <<< COMMA HERE

modules: [
{
   module: ‘middleModule’,
   config: {
   option : ""
   }
}, <<< COMMA HERE

modules: [
{
   module: ‘last module’,
   config: {
   option : ""
   }
} <<<<< NO COMMA

hope that makes sense. hopefully that’s the problem.

Can you Zip up and upload your config file somewhere I can download it and I’ll take a look? Somewhere like pastebin.

[KirAsh4]

Hey @acdacd2, please use proper Markdown when posting code. It really isn’t that hard to do and it makes it so much easier and pleasant for others to read, and possibly find errors quicker. Specifically you need to use back ticks before and after your code:

     ```
     like so. Note that a back tick is not the same as the normal apostrophe, ` versus ' .
     ```

@KirAsh4 can you confirm MM startup with my module with this config file?

The module won’t show any results but MM should boot?

[KirAsh4]

The file ‘status.xml’ doesn’t exist on my system, so it gets a 404 returned, however it does load up, and it does work.

[acdacd2]

I have the same message with my environment.
In a browse it’s ok

[KirAsh4]

Right, I have not tested this on an actual rpi … I’m at the office, so I’m running a serveronly setup. I can do an rpi test later, although I suspect it will still work, as opposed to resulting in a blank screen. It returns the error as expected when it can’t find the file.

[acdacd2]

with a browser on the pi, it’s also ok

[Eunanibus]

@KirAsh4 I’ve isolated the issue as a Cross-Domain Access issue. Do you know of any particular way to make XMLHTTPRequests to external domains?

I wasn’t aware this would be an issue but apparently anybody who wants to use this and map to an external domain will have this issue unless they have a running PHP server that can store the XML results locally (or if they can access a server, they can add the line Access-Control-Allow-Origin: * to their HTML headers.

Any ideas?

[KirAsh4]

XMLHTTPRequest. Look at how the 'currentweather' module does it in the 'updateWeather()' function.
