@strawberry-3.141 Hi thank you.
Sorry for the questions, i´m new in .js.

Where do I insert the nodehelper und the module and and what I need to modify?
I have insert the nodehelper code in the file: MagicMirror/modules/node_modules/node_helper/index.js.
And the module code in /MagicMirror/modules/sensor/sensor.js.

on the mirror is displayed : Sensor module_2_sensor…

there is a general design your module have to look like

you have to create a directory in ~/MagicMirror/modules/YOUR_MODULE_NAME

then create a file YOUR_MODULE_NAME.js

Module.register("YOUR_MODULE_NAME",{
    //here comes the rest of the code for module I posted above
});

then create a file node_helper.js

const NodeHelper = require("node_helper");
const fs= require("fs");

module.exports = NodeHelper.create({
    //here comes the part of the nodehelper after the 3 dots as posted above
});

@strawberry-3.141 Thanks for the fast answer :)

I did it , just as you said it. on the mirror is displayed : NO DATA

Here is the code from the nodehelper:
Is the path specified correctly or I need to change something?

• readData: function(){
  //to read a file to do the following
  fs.readFile(‘/home/pi/MagicMirror/Test-temp.txt’, (err, data) => {
  if (err) throw err;
  this.sendSocketNotification(‘DATA’, data);
  });

i think this should do the job

fs.readFile('Test-temp.txt', (err, data) => {

@strawberry-3.141
hi, now i get " [object ArryBuffer]"
what did i worng?

[strawberry 3.141]

sry wasn’t aware of that a buffer gets returned instead of a string if there is no encoding specified

fs.readFile('Test-temp.txt', 'utf8', (err, data) => {

@strawberry-3.141 said in .txt file include:

fs.readFile(‘Test-temp.txt’, ‘utf8’, (err, data) => {

Hi, sorry.
It didn´t work :/

Here is the node_helper.js code

const NodeHelper = require("node_helper");
const fs= require("fs");

module.exports = NodeHelper.create({
    //here comes the part of the nodehelper after the 3 dots as posted above
	
	socketNotificationReceived: function(notification, payload) {
    if(notification === 'START'){
        this.config = payload;
        this.readData();
        setInterval(() => {
            this.readData();
        }, this.config.updateInterval);
    }
},

readData: function(){
    //to read a file to do the following
   fs.readFile('Test-temp.txt', 'utf8', (err, data) => {
        if (err) throw err;
        this.sendSocketNotification('DATA', data);
    });
}
});



and here is the sensor.js code: 

Module.register("sensor",{
   defaults: {
    updateInterval: 30*60*1000 //reads the file every 30 mins
},

start: function(){
    this.sendSocketNotification('START', this.config);
},

socketNotificationReceived: function(notification, payload) {
    if(notification === 'DATA'){
        this.dataFile = payload;
        this.updateDom();
    }
},

getDom: function(){
    var wrapper = document.createElement('div');
    if(this.dataFile){
        wrapper.innerHTML = this.dataFile;
    } else {
        wrapper.innerHTML = 'No data';
    }
    return wrapper;
}
});

Waht did i wrong? :D
I hope you can help me.

this works for me you had everywhere weird quotes and the updateinterval was also wrong

Module.register("sensor",{
	defaults: {
		updateInterval: 30 * 60 * 1000 //reads the file every 30 mins
	},

	start: function(){
		this.sendSocketNotification("START", this.config);
	},

	socketNotificationReceived: function(notification, payload) {
		if(notification === "DATA"){
			this.dataFile = payload;
			this.updateDom();
		}
	},

	getDom: function(){
		var wrapper = document.createElement("div");
		if(this.dataFile){
			wrapper.innerHTML = this.dataFile;
		} else {
			wrapper.innerHTML = "No data";
		}
		return wrapper;
	}
});

const NodeHelper = require("node_helper");
const fs= require("fs");

module.exports = NodeHelper.create({
//here comes the part of the nodehelper after the 3 dots as posted above

	socketNotificationReceived: function(notification, payload) {
		if(notification === "START"){
			this.config = payload;
			this.readData();
    			setInterval(() => {
        			this.readData();
    			}, this.config.updateInterval);
		}
	},

	readData: function(){
		//to read a file to do the following
		fs.readFile("Test-temp.txt", "utf8", (err, data) => {
			if (err) throw err;
			this.sendSocketNotification("DATA", data);
		});
	}
});
