Note since it is an important comment, but I am using a converted laptop LCD driven by this controller board which requires 12V DC with 3+ A.

@costascontis said in weird problem with mm and motion(noob inside):

i changed the motion ‘Stream_port’ to 8181 but its still coming out on mm

edit: but motion’s webcontrol port was at 8080 so i changed it and now its ok .Thnx for the idea mate .

I am just chiming in to confirm that I had the same issue and to provide a clear resolution for future reference.

The problem was that Motion was creating a webcontrol element on the same port as Magic Mirror. This resulted in a black screen (the motion HTML file) showing the camera top of my monitor display instead of Magic Mirror.

To fix this, edit /etc/motion/motion.conf and change the 8080 port entry to something else, like 8181.

I’m in the UK so a 240V country. For most compact mirror builds, we won’t be able to house an entire AC power strip in the mirror.

As I understand it, in order to power an LCD monitor (12V, 3-4A) and a Raspberry Pi 4, our two options are:

• Option 1: Two separate AC to DC power supplies

• Option 2: Single 240V to 12V power supply then buck convertor from 12V DC to 5V DC

Which option is preferable?
