    Hi Sam,

    I take a look at that code. I can read it. ;) But can’t find the answer.

    This are my thougts. From start() I send

    this.sendSocketNotification('CONFIG', this.config);
    

    The this.config payload is needed at the node_helper.js at two places. One to figure out the csv file and do the MQTT stuff.

    CSVToJSON({ ignoreEmpty: true, trim: true })
    		.fromFile(CSVfile)
    		.then((jsonObj) => {
    			//console.log(jsonObj);
    			this.subscriptions = (jsonObj); //JSON.parse
    			this.setconfig(payload);
    		})
    

    I forward the this.config to the MQTT function. The array subscriptions is available there. At the MQTT function:

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

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

    I am not a programmer as you can see…just using reverse engineering and read a lot of configurations. I am almost there, I think.

    Regards,
    Bert

      @bdeelman you would save the config value in a variable usable by all routines in the source file.

      u do not need to save in the modulename.js, as it is provided as this.config

        @sdetweil can you be more precise? I did not understand you.

        The subscriptions is the generate json array with all kind of information to build an element / divs etc. That array is build at node_helper.js and globally needed within modulename.js.

        As I understand the way of working well…?

        Regards,
        Bert

          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…
