      Sound a little bit long to me, for me it works faster. But it took a while until they are startet. Do you use default settings?

        My logs file is also a bit weird:

        This is a 3min part of the logs and the 1st time I was in front of the mirror and recognized by the module this evening.

        My settings are:

        		{
			module: 'MMM-CECControl',
    				config: {
      					  // Comport of your Raspberry Pi
      					  comport: 'RPI',
      					  // Turn the TV off if the Mirror start
       					 offOnStartup: true
    					}
		},
		{
    			module: 'MMM-MotionControl',
   				 config: {
     					   // Delay to turn the TV off
       						 delay: 60000,
       					 // Interval to check modules
 					       interval: 5000,
 				       // Use the module MMM-Facial-Recognition-OCV3
  				      useFacialRecognitionOCV3: false,
   				     // Use the module MMM-Face-Reco-DNN
   				     useMMMFaceRecoDNN: true,
   				     // Array where tv should be on
				        ontime: []
					    }
		},
		{
			module: 'MMM-Face-Reco-DNN',
    				config: {
      					// Logout 15 seconds after user was not detecte anymore, if they will be detected between this 15 Seconds, they delay will start again
      					logoutDelay: 30000,
      					// How many time the recognition starts, with a RasPi 3+ it would be good every 2 seconds
      					checkInterval: 2000,
      					// Module set used for strangers and if no user is detected
      					defaultClass: 'default',
      					// Set of modules which should be shown for every user
      					everyoneClass: 'everyone',
      					// XML to recognize with haarcascae
      					cascade: 'modules/MMM-Face-Reco-DNN/tools/haarcascade_frontalface_default.xml',
      					// Pre encoded pickle with the faces
      					encodings: 'modules/MMM-Face-Reco-DNN/tools/encodings.pickle',
      					// You wanna use pi camera or usb / builtin (1 = raspi camera, 0 = other camera)
      					usePiCamera: 1,
      					// Method of face detection (dnn = deep neural network, haar = haarcascade)
      					method: 'dnn',
      					// Which face detection model to use. "hog" is less accurate but faster on CPUs. "cnn" is a more accurate deep-learning model which is GPU/CUDA accelerated (if available).
      					detectionMethod: 'hog',
      					// How fast in ms should the modules hide and show (face effect)
      					animationSpeed: 0,
      					// Path to Python to run the face recognition (null / '' means default path)
      					pythonPath: null,
      					// Should shown welcome message over alert module from MagicMirror
      					welcomeMessage: true
    					}
		},

            Depends on how you define working fine…The face recognition is working quite good, setting it up is easy with the advice you get in this thread. For me it’s just the “slow” reaction to activate the display which is an issue. But I’m optimistic that there is a way to solve it and I have a special environment with a display which hasn’t CEC control.

                I am turning on the monitor using a PIR sensor and it is instant. Keep in mind that it also depends on your monitor, some are slower to respond - this is my second monitor, the first one was very slow to respond to any HDMI related commands.

                  I have a new strange error and I think it’s just if I restart mm with “pm2 restart mm”. If I reboot my pi, everything is fine.

                    I get this too, when my PI can’t connect to the camera. I know that, because if i use
                    Raspistill -o s.jpg
                    I will get an error there too. A reboot seems to fix it though. I don’t know what makes it happen, but i suspect the cable.

                      @Blauenfeldt the python code returns an error, but the module does not expect it, and fails.

                        Will this work if the camera is rotated? If not, can you tell me where I need to change the code?
