@rico24 and here is an updated node_helper, that rejects connecting clients if they don’t send the right kind of identifier (ends with a digit)

var NodeHelper = require('node_helper');
var request = require('request');
module.exports = NodeHelper.create({
		initial_counter:10000,

        start: function() {
			this.countDown = {} 				
	},
	isDigit: function(x){
			return (x>='0' && x< ='9')  // watch out for spaces after < , forum hides it all
	},
        socketNotificationReceived: function(notification, payload) {
                console.log("Payload: =" + JSON.stringify(payload));
                switch(notification){
                        case "DO_YOUR_JOB":
				if(this.isDigit(payload.identifier.slice(-1))){
					if(!this.countDown.hasOwnProperty(payload.identifier+this.ourpage)){
				           this.countDown[payload.identifier]=this.initial_counter;
					}
				let return_payload={identifier: payload.identifier, value:(this.countDown[payload.identifier] - payload.value)}									 
                            this.sendSocketNotification("I_DID",return_payload )
			        console.log("Payload 2: = " + JSON.stringify(return_payload));
			}
			else
				this.sendSocketNotification("I_DID_REJECTED_INVALID_IDENTIFIER",payload )
                                break
                }
        },
});

@bolish I do not know… as I said, none of my TVs support ANY commands to turn off/on…

in my MMM-SleepWake module, I use module.hide() to hide everything, leaving a blank screen… for those devices that do not provide external control…

@mri_ice

from the doc
https://docs.magicmirror.builders/getting-started/installation.html#client-only

because the system is running wayland
you need to set the variable if not set

"WAYLAND_DISPLAY="${WAYLAND_DISPLAY:=wayland-1}" node clientonly … rest of parms

copied from package.json

this is what that would look like… as u want pages insulated from each other as well as module instances

module

/* Magic Mirror
 * Module: name of module
 * 
 */

//Register module
Module.register("MMM-DutchGarbageCalendar", {
  defaults: {
        foo: "I'm alive!"
  },
	ourpage: Math.ceil(Math.random() * 100),	
	count:{},
  
  //Start function
  start: function (){
  this.count[this.ourpage] = 0
},
  
  
 //getDom Function
  getDom: function() {
  var element = document.createElement("div")
  element.className = "myContent"
  element.innerHTML = "Hello, World! " + this.config.foo
  var subElement = document.createElement("p")
  subElement.id = "COUNT"
  element.appendChild(subElement)
  return element
},


//NotificationReceived 
notificationReceived: function(notification, payload, sender) {
        switch(notification) {
                case "DOM_OBJECTS_CREATED":
                        var timer = setInterval(()=>{
		        Log.log("send socket notificationR: DO_YOUR_JOB:"+this.count[this.ourpage])
			this.sendSocketNotification("DO_YOUR_JOB", {identifier: this.identifier+this.ourpage, value:this.count[this.ourpage]})
                                this.count[this.ourpage]++;
                        }, 5000)
                        break
        }
},
 
 //socketNotificationReceived
socketNotificationReceived: function(notification, payload) {
        switch(notification) {
                case "I_DID":
			if(payload.identifier== this.identifier+this.ourpage){
				var elem = document.getElementById("COUNT")
				elem.innerHTML = "Count:" + payload.value
				Log.log("socketReceived:" + JSON.stringify(payload))
			}
			else
		        	Log.log("notification not for us");
                        break
        }
},
})

helper

var NodeHelper = require('node_helper');
var request = require('request');
module.exports = NodeHelper.create({
		initial_counter:10000,

        start: function() {
					this.countDown = {} 				
				},

        socketNotificationReceived: function(notification, payload) {
                console.log("Payload: =" + JSON.stringify(payload));
                switch(notification){
                        case "DO_YOUR_JOB":
                  		if(!this.countDown.hasOwnProperty(payload.identifier+this.ourpage)){
					this.countDown[payload.identifier]=this.initial_counter;
				}
				let return_payload={identifier: payload.identifier, value:(this.countDown[payload.identifier] - payload.value)}
                                this.sendSocketNotification("I_DID",return_payload )
                                console.log("Payload 2: = " + JSON.stringify(return_payload));
                                break
                }
        },
});

@sanaa1369 the instructions say to copy the sample to config.js

looks like electron (browser) is confused about the os running

@laurafox08 sure, u install once, and can run full, server only or client only

client only really is browser to server.

so u can do what u want easily

the default install config assumes everything locally…

so, just change the config.js to allow any system on your network to connect

address:"0.0.0.0",

and initially disable any security filtering

ipWhitelist:[],

for pi0, my install script sets up chromium over server, as electron isn’t available pre built for armv6.

if u used my script see the run-start.sh script for the chromium command syntax
address:“0.0.0.0”,

@chandra move one to a different GPIO pin and change the config as required for that

@mri_ice if you look at package.json you can see the npm commands we defined in the scripts section

i copied the wayland stuff from there.

@fufu1408 said in Tv Fire Stick second Display Sound Bluetooth:

Can i connect Bluetooth speakers to the controller board of the TV fire stick

seems so

https://thehometheaterdiy.com/use-bluetooth-speakers-with-amazon-fire-tv-stick/

@bhepler aws also provides generated keypairs.

I just created a server the other day to host an app. I have both ssh and scp’ed to that server from windows and my mirror and my Linux machine

@FrostByte as long as the change doesn’t affect a node_helper, which are only loaded at start time

the config.js os loaded as part of the web page
there is no notification it changed to the client browser

@macg said in fix for black screen in 2.16 and later:

The “strange” referred to the fact that I have no problems with MMM-DWD-WarnWeather, but others have to install the module “request”.

did u npm install request in the mm folder, or in a module folder where there was no package.json, the latter ends up putting it in the mm/node_modules, the same as the former

@veejae addess: “localhost”, means listen ONLY inside (from myself)…

change to address: “0.0.0.0” (listen from anywhere)

@ember1205 I had to make my browser page bigger…
you could zoom out ctrl-minus (on the keypad) or the -/+ on the US keyboard to the left of the backspace key)

blocked,

zoomed out 1 click (ctrl-minus)

@oberfragger yes, if you use the bullseye adjusted url (note the word master is replaced by bullseye i the url)

bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/bullseye/raspberry.sh)"

I don’t want to break the current version while we test this out…

I just updated the instructions with this link

@qu1que ok, even more manual…

my script does all that plus pm2. and screen saver turn off…
any os… mac, ubuntu, pi stretch, buster, pi0 thru pi 4, odroid, jetson nano, sure others…

@monark yes, the complexities are increasing. in number and difficulty.

the add on capability from MagicMirror means anyone of any skill can do just about anything.

I support the install/update and backup/restore scripts for MagicMirror, mostly to help with some of these difficulties… nodejs for example…

the general view is that this MagicMirror environment is a learning experience, and we shouldn’t gloss over it… but I want to help users make progress and be successful.

but its hard with all the technical churn OS, runtimes, libraries, …

access to camera and OpenCV, python, are outside MM, we don’t know about any of it.
causal (maybe first/only time) developers speak what they know…

but I feel your pain.

@nneuland you didn’t do the npm install in the module folder

@blackeaglece if u would like to try sequential,

download my repo and copy the compliments.js file to your instance

# get new code
cd ~/MagicMirror/modules
git clone https://github.com/sdetweil/MagicMirror.git  temp_mirror
#
cd ~/MagicMirror/modules/default/compliments
mv compliments.js compliments.js.save

cd temp_mirror/modules/default/compliments
git checkout fixcompliments
cp compliments.js ~/magicMirror/modules/default/compliments

edit the config.js and in the compliments module config section, add
make sure its in the config block

config: {
     random: false,
}

then restart you mirror
