How to Change MMM-DWD-WarnWeather Module for Switzerland

Squirrel

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’]

@Squirrel result['alarms'][0]['regions'][0]['name_de'] returns Agglo BE you have to access arrays [] with the index (starting with 0) and access objects {} with the property names

@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' 
    }
 ]

@Squirrel you are pushing every single propertie to the array instead of the whole object

if (result['alarms'][regionId]['regions'][0]['name_de'] == region) {
  var warnings = {};
  warnings.start = result['alarms'][regionId]['valid_from'];
  warnings.end = result['alarms'][regionId]['valid_to'];
  warnings.regionName = result['alarms'][regionId]['regions'][0]['name_de'];
  warnings.level = result['alarms'][regionId]['priority']
  warnings.type = result['alarms'][regionId]['code']
  warnings.altitudeStart = undefined;
					
  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";}

  warnings.headline = result['alarms'][regionId]['de']['title'];
  warnings.description = result['alarms'][regionId]['de']['paragraph'];
  warningData.push(warnings);
}

try this instead

Thanks again for fast Answer! Now everything is working. Im so happy! :)

I have just one last Question. I tried to run both modules at the same time. This is giving me problems. The Icons are too much big and i cant see something else…

I changed all the names of the module files and folders and i have no idea where i can find this fault. I think nobody gonna us this two modules at the same time but i want to upload my module for other users and if somebody is using both of them i dont want to destroy @LukeCodewalker s module… ;)

Squirrel

I uploaded my Project MMM-WetteralarmCH now! If somebody can help me with the problem of using both modules (MMM-WetteralarmCH and. MMM-DWD-WarnWeather) at the same time i gonna update my Project again.

Thanks to everybody for helping me!

Sorry for being absent so long. Busy times in the moment :) but I’m glad to see that you’ve got it working. :thumbsup:

Squirrel

@LukeCodewalker thanks! But I still need a Solution to don’t Crash your Module while both modules are running at the same time… Let me know when you have more time to talk about that topic 😉
