    @bdeelman said in Use of array within all module files:

    These payloads arrived within the function at the module file. But I can not use the payload outside of that specific function.

    so in the receiving function, store the payload value somewhere that other functions can use it

    this.subscriptions=payload

    similar for the config info in the node_helper

      @sdetweil Thanks for your reply. Much appreciated!

      I think I need another approach to get the result that I need. The subscriptions array is (must be) part of the this.config. So I add subscriptions: [];to the defaults: at the modulename.js

      The thing now is add the generated JSON (csvtojson) to the this.config. :grinning_face_with_big_eyes: and I can use this.config as a payload.

      The array is something like this:

      subscriptions = [{
          topic: 'homey/light/keuken/dimmer-fibaro-1/onoff', // MQTT Topic name
          label: 'Licht keuken',
          type: 'device',
          display: { left: 50, top: 50  },
        },
      {
          topic: 'homey/sensor/washok/temp-hum-xiaomi-1/measure-temperature',
          label: 'Washok Temp',
          type: 'label',
          display: { left: 265, top: 0, prefix: "", suffix: "°C", decimals: 0 },
      }

        @bdeelman sorry I do not understand what you want

        u can send anything with sendSocketNotification and you can store it anywhere, not just in this.config

          @sdetweil I am sorry and lost. ;)

          The sendSocketNotification from node_helper.js

          self.sendSocketNotification('MQTT_PAYLOAD', {
          				topic: topic,
          				value: value,
          				subs: self.subscriptions
          				)};
          

          So if I understand correctly…I should add this.subscriptions = payload; at the receiving function socketNotificationReceived at modulename.js

          socketNotificationReceived: function(notification, payload) {
          	this.subscriptions = payload;
            if (notification === 'MQTT_PAYLOAD') {
          // 
          //
            }
          },
          

          I did that but it is not working. The array is not available at other functions within modulename.js.

          At the node_helper part it is working. this.subscriptions = (jsonObj);and I can use the array at other functions. with

          var self = this;
          var l = self.subscriptions.length; // as an example.

            @bdeelman so, I would open the developers window., ctrl-shift-i on the pi MM window
            select the sources tab, navigate the left nav modules/your module name, select the source file name modulename.js

            scroll to the line for the socketNotificationReceived().
            this.

            and click the number at the left edge of that line, should turn blue

            then hit f5 to refresh the page, and MM will reload and you should stop at the line…

            move your mouse over the word ‘this’, and it should expand a box describing what this points to , which should be THIS modules instance data…

            if not, then THAT is the problem…
