Electricity Bill Module Development

[SopaMaruchan]

Hi there!
I’m developing a new module for a Magic Mirror to display Electricity Bill data but I’m struggling with something. The thing is that I consume an API which requires Bearer Token as an authentication to retrieve the data. I handle it using a node_helper file, but the thing is that I only get to display the data on the console but not visually on screen:
How can I send that data from node_helper to my MMM-CFE and place it on a meter element?
MMM-CFE:

node_helper:

Thought of socketNotification but I couldn’t figure it out, any ideas?

@SopaMaruchan get data from API

let’s call the object foo

then

this.sendSocketNotification(“fribble”, foo)

then on the module side

  receiveSocketNotification(code, data){
          if(code === 'fribble'){
                 this.savePointer = data
                 this.updateDom()
          }
   }

then

      getDom(){
               //  use  this.savePonter
      }

@sdetweil I named my retreived data as “foo” and then used sendSocketNotification as you previously told me but I got this as output:

I did it this way on my node_helper file (Highlighted the lines I added):

Did I missed anything?

[sdetweil]

@SopaMaruchan ah, so much fun!

you are inside the callback of the request,so ‘this’ I pointing to some request object and not the node_helper instance…

sooooo

before request(…

add
let self = this

and change this. to self.

object oriented programming is tricky

[sdetweil]

@SopaMaruchan and {foo} is unnecessary

you could just use
res.body

it’s the same stuff, why waste memory w a new pointer only being used once

(same w info there too)

[SopaMaruchan]

@sdetweil Hahahaha true that!
Kinda fixed it guided by your recommendations but the thing is that I’m still getting the same output:
Here the code:

[sdetweil]

@SopaMaruchan hm…

sample from one of my modules

self.sendSocketNotification("SLEEP_HIDE")

[SopaMaruchan]

hmm, actually it does help. I’ll be testing around and tell you when I get it to work!
Anyways your help was a huge pilar to keep myself going with this, much thanks brother💝

[SopaMaruchan]

Does it help if I tell you that I got everything on my onstart function of the node_helper file?

[sdetweil]

@SopaMaruchan never done it in start.

I usually wait til the module sends it’s 1st request
