    @Beh Thx for sharing! One question : what are the physical settings to apply to the sensor itself pls? (Jumper & the 2 knobs)

      Example configurations for wiring are shown here:

      and here:

      https://www.raspberrypi.org/learning/parent-detector/worksheet/

      I can’t really tell you the jumper and knob configurations, because I’m using a simple sensor like this:

      Maybe you look in the PIR HOWTO thread or ask a question there:

        @Beh i see thx! maybe it’s better to use your one to somehow bypass these settings which are a bit frustrating. i did’t really get the systemd option (i am new) but as i understood it’s like a crontab, correct?

          @bibi No, it’s more like having it added to the autostart (like on windows). Then it’s running as a service in the background, which can be controlled via systemd’s systemctl command.

                @beh hi! i was wondering if there was an easy way to add a fading effect when the mirror goes to sleep and wake up? would be interesting in this as well? thx

                  Hi @bibi, I hope, I understand that right.

                  I don’t think that this is very easy. Because the script just turns the HDMI port of the RaspberryPi to on and off. So a fading effect wouldn’t be quite easy I think
