    @yo-less Thanks!

    The mirror is from a dutch webshop… At night, when there’s no other illumination you do see the backlight of the screen shining through… In the daytime it looks like the picture.
    I’ve been pondering altering the backlight/brightness of the screen according to ambiant lightlevels… unfortunately this is only controllable by navigating the screens menu as opposed to discrete buttons…

    Oh, and yes… there is: https://github.com/RedNax67/DailyXKCD

    It’s forked from the original author… Ive added the random comic on non comic days…

      @RedNax Alright, is that the case with all types of glasses? I guess it would be?

        @yo-less It think all mirrors suffer from this… You need enough brightness to show things in the day… Which will be overkill at night…

          @RedNax Apparently some monitors seem to allow for external commands to change the light levels:

          They seem to have to support DDC/CI and if there is a tool for Windows PCs there should be some way to get the same thing done on a Pi?

            @yo-less said in PIR sensor behind glass?:

            Can a PIR sensor be covered by anything at all or does any kind of material automatically block motion detection?

            You really can’t cover a PIR it just won’t work… BUT you can remove the ‘dome’ and incorporate into the frame a little better OR you can just put it into the frame with the ‘dome’ on it and make it decorative…

              @yo-less changing the brightness would be really nice… having it automatic would be better… you know at a certain time of night it dims automatically… but there is this…

                @cowboysdude Thanks for the link. Does f.lux have access to the monitor’s brightness settings? As this has nothing to do with my original question I will start a new topic concerning the brightness issue at night.

                  @cowboysdude We might just drill a tiny hole into the frame of the mirror and put the PIR behind it without its Fresnel cover. Will experiment with that idea some more.

                    That’s the approach I was thinking of. Which PIR will you use?

                      @yawns I’ve got the HC-SR501 / D-SUN RCW-0506 and it’s working as it should.
                      I paid €8 for two sensors and shipping to Germany. The one in use even survived my failed attempts at connecting it to the correct pins :).
