Hi,

I convert a CSV file to a JSON array at the node_helper.js file. This array (subscriptions) is needed at several functions at the mmm-sample.js file.

The array is available at other functions within the node_helper.js I use this.subscriptions = (jsonObj); within the CSVtoJSON function and declare var subscriptions = []; at the top of nodehelper.js and also at the mmm-sample.js.

How can I achieve this? Do I need the sendSocketNotification functionality to send data back and forth between the files?

Any help is much appreciated.

Regards,

@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.

@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. 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 },
}

@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…?

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.
