earlier versions of mirr.OS

Tutorials

The information refers to the earlier version of mirr.OS alone, not to mirr.OS one.

The setup and the use of mirr.OS including the modules is actually a piece of cake. If you still have problems, you can check out the tutorials here.

FAQ

… and the most common answers.

How do I access my Smart Mirror via SSH?

ssh pi@your.ip.address
User: pi
Password: glancr!2017

mirr.OS does not find my WiFi

If this still didn’t work, check if you really entered a correct mail address (spaces, mistyping etc.)

If everything has been entered correctly, please connect a keyboard via USB and switch to the console with the key combination Ctrl+Alt+F1.

Log in there (User: pi / PW: glancr!2017)

type in service dnsmasq status

if the status is “active”, with the command

sudo systemctl disable dnsmasq and restart mirr.OS with sudo reboot

I want to change the display orientation

Connect to your Pi via SSH. Via command

sudo nano /boot/config.txt

you can change the line “Display Rotate”. More info. Save and restart. Done.

I would like to change the appearance

From version 0.7.8 it is possible to override the CSS rules in a simple way. It works like this:

1. create a file “custom-styles.css” on your computer and write your rules in it
2. log in on the Pi via FTP (how? see above!)
3. loads the file into the folder /var/www/custom/

Done. Reload the output on the mirror once via the configuration interface.

How do I change the background?

In the folder /var/www/custom/ you can also load your desired background image. Then write the following in the custom-styles.css:

body {
background-image: url("mein-hintergundbild.jpg"); /* Zeile löschen, wenn nur Farbe gewünscht ist */
background-color: #cccccc; /* Farbwerte über Grafikprogramm finden */
}

Sometimes the images are too dominant and you can’t read the font of the modules well. Then you want to reduce the opacity of the image. This can be done with the specification “opacity”. The CSS would look like this:

body::after {
content: "";
background: url(mein-hintergundbild.jpg);
opacity: 0.5; /* hier die Deckkraft einstellen */
top: 0;
left: 0;
bottom: 0;
right: 0;
position: absolute;
z-index: -1;
}

If you don’t want to upload an image, you can also enter a complete URL to an image on the Internet. Remember that the image should have a resolution like your display.

My display shows nothing / I want to change the resolution

mirr.OS is configured to the resolution of 1920 – 1080 px to match the displays from our build instructions. Depending on the switching order, the Pi may not correctly detect the resolution of the connected monitor and then only output 800 – 600px. If your monitor has a different resolution, you can change this as follows.

1. Connect to the Pi via SSH (instructions above)
2. Enter the commandsudo nano /boot/config.txt
   and confirm it
3. In your editor, look for the line that says:framebuffer_widthund framebuffer_height Enter the resolution of your monitor there. Attention: portrait format, i.e. the larger number is the height. Only the pure number, no px behind it.
4. If you don’t know the resolution of your screen, you can also disable both lines by putting a hash (#) at the beginning of the line.v
5. Save with Ctrl+O, then Ctrl+X to exit the editor.
6. Reboot the Pi with the commandsudo reboot
