MMM-Facial-Recognition cannot sendSocketNotification()

  • Hi,

    I’m trying to get the troubleshoot the MMM-Facial-Recognition module, and I have narrowed it down to the node_helper not being able to sendSocketNotification().

    I added a line to socketNotifcationRecieved() within the node_helper.js file to test this.

      // Subclass socketNotificationReceived received.
      socketNotificationReceived: function(notification, payload) {
        if(notification === 'CONFIG') {
          this.config = payload
          if(!pythonStarted) {
            pythonStarted = true;
            this.sendSocketNotification("Test", "sendSocketNotification to module");

    and then I also added a console.log to the MMM-Facial-Recognition.js to print out any received socket Notifications.

    	socketNotificationReceived: function(notification, payload) {
    		//For testing purposes

    However, nothing prints out in the console.

    I am troubleshooting this, because even though the module recognizes my face and logs me in, no alert comes up on the mirror and none of the modules update.

    Note: The module itself is able to sendSocketNotification to the node_helper because the python_shell does start and the recognition python script runs with the correct configuration.

    Thank you in advance for your help.

  • UPDATE: This, like some other issues I was running into was actually caused by the application freezing when it could not load ‘css/custom.css’.

    This is because the .gitignore does not track custom.css and I, like many others, edit my code on my desktop and then push the changes via git to my RPi.
