    Hi, I’m a total noob to all this, but have recently started a project to build a magic mirror. I’ve got MagicMirror setup, and have the modules I want working. Now I’d like to use the motiondetector module, but although it appears to run without any error, the monitor itself is not turning off.

    I’ve tested the camera module and that is working, and I can see an image / record video etc. I’ve also tested running the tvservice commands directly and both of these work as expected:

    /opt/vc/bin/tvservice -o
    /opt/vc/bin/tvservice --preferred && sudo chvt 6 && sudo chvt 7

    Only change I have made is to the timeout (30000 so I’m not waiting for too long before the screen should turn off).

    My config.js has the following entry for motiondetector:

    	]
    };
    
    /*************** DO NOT EDIT THE LINE BELOW ***************/
    if (typeof module !== "undefined") {module.exports = config;}
    

    Weird thing is, if I try to have a config section in the config.js with the timeout, and restart MagicMirror, I get an error that the config.js is corrupt. But if I remove the config part, MagicMirror loads without error. MM log below:

    Any ideas on what could be the problem?

    Thanks…

      @strawberry-3.141
      Thanks for your help. Unfortunately I don’t find any information about media access or how to activate it in the Midori browser…

      @mongo116
      I cant’ help you why the motiondetector does not turn off your screen (it also does not work in my case). However, how does the config.js with the additional time-out section that results in an error look like? At least in my case a section like

      {
                         module: 'motiondetector',
                         config: {
                                 timeout: 5*60*1000
                         }
                 },
      

      gave no complaints about errors in the config file (for a complete config-file see my post above).

        @Hawking Thank you, that works. Monitor is still not turning off, but that’s one issue off the list :)

          Just to add to this, I have checked that the camera is working and motion is detected by testing with https://github.com/pageauc/motion-track. All appears to be working as expected. No motion is detected unless I move in front of the camera.

            @mongo116 maybe the value that gets returned is different than the value set in the module, so he always tries to activate the monitor?

            Please create a github issue if you need help, so I can keep track

              I’ve got the motion detection now working - had to add bcm2835-v4l2 to \etc\modules - restarted and screen now turns off after defined period and on when motion is detected. This is really great, and I’m nearly there - but… Now when the motiondetector is running, the RPi3 temp just goes up and up and up, until it eventually crashes/freezes and I have to pull the power as RPi is completely unresponsive. If I remove motiondetector from MagicMirror, temperature stays stable and no crashing. Is there something I can change in the config to sort out this performance issue?

                @mongo116 it looks like https://github.com/alexyak/motiondetector/blob/master/diff-cam-engine.js#L37 it creates 10 images per second and compares it to the previous which is probably the intensive part

                  @strawberry-3.141 Thanks for that. I’ve amended this slightly so will keep an eye on it. Might also have a look at putting on some heatsinks to see if that helps.

                  One (hopefully!) final question. When the monitor is turned off, is there a way to ‘freeze’ the other modules, so they stop running for the duration that the monitor is off? This would hopefully help with performance, in that the other modules are no longer running.

                    @mongo116 every module has a suspend and resume function, but nearly none module that I’m aware of has implemented stopping intervals and fetching data in there. so calling those functions wouldn’t make a difference then just hiding it on the display.

                    Furthermore I doubt that it would really make a difference if you’re not using another cpu intensive task like voice recognition …
