@strawberry-3-141 thank you for your fast and competent answer.

This is what i did now:

......

request ( {
          url: url,
          method: 'GET'
		  }, 

           function (error, response, body) {

			var result = JSON.parse(body);
			var warningData = [];
			
			for (var regionId in result['alarms']) {

                			if (result['alarms'][regionId]['regions'][0]['name_de'] == region) {
					var warnings = new Object();
					warnings.start = result['alarms'][regionId]['valid_from'];
					warningData.push(warnings.start);
					warnings.end = result['alarms'][regionId]['valid_to'];
					warningData.push(warnings.end);
					warnings.regionName = result['alarms'][regionId]['regions'][0]['name_de'];
					warningData.push(warnings.regionName);
					warnings.level = result['alarms'][regionId]['priority']
					warningData.push(warnings.level);
					warnings.type = result['alarms'][regionId]['code']
					warningData.push(warnings.type);
					warnings.altitudeStart = undefined;
					warningData.push(warnings.altitudeStart);
					
					if (warnings.type == 1){warnings.event = "Frost";}
					else if (warnings.type == 2){warnings.event = "Gewitter";}
					else if (warnings.type == 3){warnings.event = "Grossflächige Glätte";}
					else if (warnings.type == 4){warnings.event = "Kräftiger Regen";}
					else if (warnings.type == 5){warnings.event = "Schnee";}
					else if (warnings.type == 6){warnings.event = "Sturm";}
					else if (warnings.type == 7){warnings.event = "Hochwasser";}

					warningData.push(warnings.event);

					warnings.headline = result['alarms'][regionId]['de']['title'];
					warningData.push(warnings.headline);
					warnings.description = result['alarms'][regionId]['de']['paragraph'];
					warningData.push(warnings.description);
				}
			}
			self.sendSocketNotification('WARNINGS_DATA', {warnings: warningData, region: region});

			console.log(warnings);
			console.log(warningData)

		});

          .......

Now i got the following outputs:

// With console.log(warnings);

{ start: '2017-01-16T21:00:00.000Z',
  end: '2017-01-19T00:00:00.000Z',
  regionName: 'Seeland/Bielersee',
  level: 1,
  type: 6,
  altitudeStart: undefined,
  event: 'Sturm',
  headline: 'Starke Windböen',
  description: 'eisige Bise. 21 Uhr bis Do 00 Uhr' }

// With console.log (warningData)

[ '2017-01-17T00:00:00.000Z',
  '2017-01-18T23:00:00.000Z',
  'Seeland/Bielersee',
  1,
  3,
  undefined,
  'Grossflächige Glätte',
  'Gefahr von grossflächiger Glätte',
  'durch Schneeglätte. Di 00 Uhr bis Mi 23 Uhr',
  '2017-01-16T21:00:00.000Z',
  '2017-01-19T00:00:00.000Z',
  'Seeland/Bielersee',
  1,
  6,
  undefined,
  'Sturm',
  'Starke Windböen',
  'eisige Bise. 21 Uhr bis Do 00 Uhr' ]

My Problem now is that my Output is still looking different than his output. And when i get 2 warnings for the same Region the Output goes into the same Array… By the Way… Why i get only one Warning for the region with console.log(warnings);

Here is the Output example of his module:

[ { start: 1484586000000,
    end: 1484650800000,
    regionName: 'Kreis Harburg',
    .....
    state: 'Niedersachsen' 
  },
  { start: 1484586000000,
    end: 1484650800000,
    regionName: 'Kreis Harburg',
    .......
    state: 'Niedersachsen' 
    }
 ]

Ok i understand. But i have problems to transfer this to my module.

the simplified structure of my json looks like this:

result = {
    "alarms": [ {
         "id":49664,
         ...
         "regions": [
               {
               "id":40,
               "name_de":"Agglo BE",
               "name_fr":"Agglo BE",
               "name_it":"Agglo BE"
                }
          ],
         ...
      },
      
 }

Now i tried as a first test to display some stuff of my JSON.

var regionId = 0; // Later i want to create a for-loop with this

console.log (result['alarms'][regionId]['regions']);

With this i got something like:

"id":40,
 "name_de":"Agglo BE",
 "name_fr":"Agglo BE",
 "name_it":"Agglo BE"

But then i tried

console.log (result['alarms'][regionId]['regions']['name_de']);

AND

console.log (result['alarms'][regionId]['regions'][1]);

But this gives me undefined as answer… I dont understand why…?
Very strange is also that i no more see the regions when i delete the last bracket again… then i get [Object][Object]as Answer!? And when i Start again with only the [‘alarms’] Bracket i can see all the Warnings and then again also the regions with [‘alarms’][regionId][‘regions’]

i got it! When i change with alt + tab to the Terminal i can close the Terminal and that also Quits my mirror! Thanks!

No. Ctrl + q is not working… It works when the mirror is running but with my white screen it is now more possible to quit it with this command…

Yes i work on raspberry directly. Sadly i did mot found a way to test my work on my mac!? Ok thanks! alt + tab is working. But it still s**** a bit when i have to restart my raspberry after ever fault i did…

I still need help. Maybe someone else can help me!? Here is the whole Part:

getWarningData: function (region) {
var self = this;

	var timestamp = Date.now().toString();
	var url = 'http://www.dwd.de/DWD/warnungen/warnapp_landkreise/json/warnings.json?jsonp=loadWarnings' + timestamp;



	request({
		url: url,
		method: 'GET'
	}, function (error, response, body) {

		var result = JSON.parse(body.substr(24).slice(0, -2));
		var warningData = [];
		for (var regionId in result['warnings']) {
			if (result['warnings'][regionId][0]['regionName'] == region) {
				var warnings = [];
				for (var warning in result['warnings'][regionId]) {
					warnings.push(result['warnings'][regionId][warning]);
				}
				if (warnings.length > 0) {
					warningData = warnings;
				}
			}
		}
		self.sendSocketNotification('WARNINGS_DATA', {warnings: warningData, region: region});

Here is the JSON Link from @LukeCodewalker and this is the JSON Link i want to use for my Module.

Dont give me too much help. I need to learn somthing but i stil don understand how is his request working (Line 32)…

Line 32: if (result['warnings'][regionId][0]['regionName'] == region) };

I try to build my own Module. When i start the MagicMirror now i get a blank white screen and i cant Quit the mirror no more. The only way to quit is a restart. but that sucks because i want to read the Terminal. When i Open Terminal then i get a new blank Terminal. How can i Quit the Terminal or how can i see my other Open Windows behind the Mirror?

It looks like this is a lot of work. ;) After watching 100s of videos and reading 1000s of tutorials i can read now the most of your code and i know that its not that easy as i was thinking. I dont give up but there are still some lines i dont understand. It looks like i need more help for the request in node_helper.
Can you tell me what the following Line is exactly doing?

Line 32: if (result['warnings'][regionId][0]['regionName'] == region) };

i dont understand why you use 4x [ ]. What i think to understand is that you search for regionName in your object warnings. I can imaging for what you use regionId (what you buildet in the line before) but i have no idea forwhat the [0] is??

@LukeCodewalker here we ;)

and here is the Output i got from mitmproxy:

curl -H ‘Host:my.wetteralarm.ch’ -H ‘Content-Type:application/json; charset=utf-8’ -H ‘Proxy-Connection:keep-alive’ -H ‘Weal-Device-ID:1015262’ -H ‘Accept:/’ -H ‘User-Agent:WetterAlarm/5.5.0 (iPhone; iOS 10.1.1; Scale/2.00)’ -H ‘Accept-Language:de’ -H ‘Accept-Encoding:gzip’ -H ‘Connection:keep-alive’ ‘http://my.wetteralarm.ch/v6/alarms/meteo/with-regions.json’

Hmm since i changed some things in node_helper.js my MagicMirror is no more working and i get the following ERROR:

This is what i did in config.js:

module: 'MMM-DWD-WarnWeather',
position: 'bottom_right',
header: 'Wetterwarnungen',
config: {
    region: 'Seeland/Bielersee',					// Kreis Lörrach
    changeColor: true,
    interval: 10 * 60 * 1000, // every 10 minutes
    loadingText: 'Warnungen werden geladen...',
    noWarningText: 'Keine Warnungen'
}

},

And here what i did in node_helper.js :

getWarningData: function (region) {
	var self = this;

	var timestamp = Date.now().toString();
	var url = 'http://my.wetter.ch/v6/alarms/meteo/with-regions.json' + timestamp;			// http://www.dwd.de/DWD/warnungen/warnapp_landkreise/json/warnings.json?jsonp=loadWarnings



	request({
		url: url,
		method: 'GET'
	}, function (error, response, body) {

		var result = JSON.parse(body.substr(24).slice(0, -2));
		var warningData = [];
		for (var regionId in result['warnings']) {
			if (result['warnings'][regionId][0]['name_de'] == region) {			// name_de = regionName 
				var warnings = [];
				for (var warning in result['warnings'][regionId]) {
					warnings.push(result['warnings'][regionId][warning]);
				}
				if (warnings.length > 0) {
					warningData = warnings;
				}
			}
		}
		self.sendSocketNotification('WARNINGS_DATA', {warnings: warningData, region: region});

	});

I changed the link and i changed regionName to name_de… Any idea? Hope this is gonna be my last Question ;)
