SleepWake twisted....need help

[justonemore]

I am trying to use MMM-SleepWake module from sdetweil (real good by the way) to communicate with my own module but can’t figure out what is wrong…everytime MMM-SleepWake wakes, it runs a python program through a function I created in the MMM-SleepWake node_helper file…It runs fine when I uncomment the console.log and comment the sendNotification lines so I know it is working. What I don’t get is how to send the data to my own module…I tried self.sendNotification, this.sendNotification and sendNotification but all of them return an error the function is not defined…how to I send “data” to my MMM-Facez module ?

Python function included in node_helper from MMM-SleepWake.

start_python: function() {
    let self = this;
    var py_recog = spawn('python3', ['-u', '/home/pi/MagicMirror/modules/MMM-Facez/recognize.py']);

    py_recog.stdout.on('data', function (data) {
//      console.log(data.toString());
      sendNotification("ATUALIZA_FACEZ", data);
    });

    py_recog.stderr.on('data', function(data) {
      console.log('Python returned Error: ', data.toString()); });

    py_recog.on('exit', function (code, signal) {
      console.log('Python exited with ' +
              `code ${code} and signal ${signal}`); });

    },		

Error I get :

      var elem = document.getElementById("TITULO")
      this.nomepessoa = payload
      elem.innerHTML = this.nomepessoa
      break

      this.nomepessoa = payload

@justonemore node_helper cannot communicate with any module except its own

via sendSocketNotification()

the MODULEname.js can then talk to other modules

via sendNotification()

here is a diagram of the design

SO, the helper sends the notification up to its module which then forwards it on

this.sendSocketNotification('send this to others', {notification:ID_of_message_to_other_modules, content: actual_message_content})

MODULEname.js does

 socketNotificationReceived(notice, payload){
     if(notice === 'send this to others')
         this.sendNotification(payload.notification, payload.content)
}

@sdetweil Thank you…
