    Greetings! I’m slowly working my way through this thread and trying to figure out what’s going on here.

    What works: configurable timeout for the motiondetector seems to work just fine. Turns the screen off. Interestingly, if I’m viewing the mirror via my desktop browser, refreshing the page will turn the monitor on.

    What doesn’t work: turning the screen on. Even after entering sudo modprobe bcm2835-vl2

    Additionally, I’m seeing this in the console with the developer tools enabled:
    getUserMedia() no longer works on insecure origins. To use this feature, you should consider switching your application to a secure origin, such as HTTPS. See https://goo.gl/rStTGz for more details.

      I just tried this module but cpu load made me stop using it. Please tell me, how busy is your Raspberry with and without the motiondetector module? Mine is as follows on a Raspberry Pi 2:

      • With motiondetector enabled, there is always an electron process with ~100% cpu
      • With motiondetector disabled, I observed one or two electron processes with up to 15% cpu

      I used a dedicated motion daemon on my old version of the mirror to switch on the screen on motion and I think I will set it up again. IIRC, it used ~40% cpu on a (single-core) Raspberry Pi 1 B+. What is your opinion?

        @paphko I just looked at my Pi 3 and I’m showing 40% usage with the motion detection module running (and failing). I suspect it’s the constant pic-compare-pic-compare loop that runs. It would be trivial to insert a wait in that loop to lower the CPU usage. Even a delay of 750 ms would probably help quite a bit.

          @bhepler you’re right. putting a delay should help with the CPU usage.

            Thanks, @alexyak. Any idea about how to get around the issue with the new security surrounding webcams?

              Hi, i had some issues with the PIR module where the screen doesn’t switch on anymore. Now with a original PI Camera i tried this module. Same issue, the screen doesn’t switch on but in this case no motion seems to be detected. (the PIR did detect)

              with /opt/vc/bin/tvservice --preferred && sudo chvt 6 && sudo chvt 7 i can switch on the screen manually.
              I followed every tip here in the thread. So i have no idea what is going on :(

              mm-0 (out): monitor has been deactivated
              mm-0 (out): monitor :state 0x12000a [HDMI CEA (16) RGB lim 16:9], 1920x1080 @ 60.00Hz, progressive
              mm-0 (out):
              
              

              That is the only thing i can see in the log.

                Check the console log. I suspect you’ll see a security error preventing the browser from accessing the monitor. Either launch your mirror in dev mode (modify your mm.sh script to read DISPLAY=:0 npm start dev and then restart via pm2 restart 0) or browse to your mirror’s address via a web browser and enter developere mode.

                  i don’t have a mm.sh script. Where should it be located?

                    @DirkS Aha. You probably haven’t set it up yet. No worries. You normally start your mirror by going into ~/MagicMirror and entering npm start, right? Just append the dev switch and you should see both the mirror UI and the browser console on your mirror: npm start dev

                    If you’re starting your mirror via SSH, prepend the command to send the output to the mirror’s display: DISPLAY=:0 npm start dev

                      The mirror is starting at reboot. So maybe there is a script, i installed it a few month ago, i don’t remember :D

                      If i’m testing new settings i use pm2 restart mm for example. npm i’m just using to install new modules.
