      I noticed that after long sleep cycles (mostly overnight), the monitor turns on with detected movement (PIR sensor), but MagicMirror itself is just a black screen with my mouse cursor. I have to restart MagicMirror with alt + f4 to load properly after the long sleep. Has anyone had a problem like this? The mirror detects the motion just fine, but I lose everything on the screen when it awakes. Thanks!

        @Matthew open the developers window ctrl-shift-i and select the console tab and scroll up to see any errors.

        black screen usually means some code running in the browser died

            @sdetweil It says that devTools was disconnected from the page. Once page is reloaded, DevTools will automatically reconnect

                @sdetweil I remember that I have some problem with an npm library with it (before I start to code)
                I don’t remember how I solve it

                After you can try my pir module if you want

                  @Matthew install this module
                  https://github.com/sdetweil/MMM-Logging

                  note that this is a modified version of this module, written by someone else… but I needed to do similar debugging a while back

                  make its module entry in config.js the top of the list, like this

                  modules: [
                          {
                              module: 'MMM-Logging',
                              config: {
                                         echoRemote:false,
                              }
                          },
                  // other modules
                      ]
                  

                  let everything else default

                  this will collect all the browser logging and console logging together with timestamps…

                  then start mm like this

                  cd ~/MagicMirror
                  npm start >somefile 2>&1
                  
                  

                  or use pm2
                  (all the logging info will be saved in the pm2 logs)

                      that happened on the 15th within 2 seconds of starting…

                      is that the right log?

                      that says something is already running … do you normally use pm2 to launch MM?

                      do pm2 status
