1. Software Introduction

MagicMirror² is an open-source modular smart mirror system (Raspberry Pi Smart Mirror) that allows you to build your smart mirror, becoming the brain of your mirror, intelligently displaying time, calendar, weather, news, voice interaction, and more. It focuses on a modular plugin system and uses Electron as the application wrapper, so there is no need to install a web server or browser.

2. Project Address

https://magicmirror.builders/

3. Features

Open source
Modules: The core of MagicMirror² includes a powerful API that allows third-party developers to build additional modules, using existing modules or developing other modules themselves
Wide community

4. Installation

Thanks to @MichMich’s excellent open-source code, installing MagicMirror is so convenient and simple.

Step 1

After setting up the Raspberry Pi, upgrading the system, and rebooting, open the terminal and enter:

bash -c “$(curl -sL https://raw.githubusercontent.com/MichMich/MagicMirror/master/installers/raspberry.sh)”

Then you will see the interface below and start the installation.

Step 2

For MagicMirror, some additional settings are required. First, set the screen to display vertically. You need to edit a boot file (Note: Vertical display is not mandatory; if you want wide display or as a landscape display, it is unnecessary) entersudo nano /boot/config.txt, add the following content, and where to add it doesn’t matter:

# Rotate display vertically
display_rotate=1

After writing, pressCTRL-X, YES to confirm save.

Step 3

Disable screensaver and lock screen. Settings need to be made in two places, first in the auto boot file:sudo nano /etc/xdg/lxsession/LXDE-pi/autostart Add the following at the end of the file, and save:

@xset s noblank
@xset s off
@xset -dpms

Then, enter in the terminalsudo nano /etc/lightdm/lightdm.conf Scroll down to find[SeatDefaults] section, findxserver-command, modify it toxserver-command=X -s 0 -dpms After writing, pressCTRL-X, YES to confirm save.(Tip: If your system is ubuntu-mate, the above settings are incorrect. You need to set both operations and display to Never in the control center – Power Preferences)

Step 4

The Raspberry Pi system will disable inactive modules by default, including the WIFI module, which may occasionally cause MagicMirror to not receive updates such as news or weather. We can disable power-saving mode in the interface file:sudo nano /etc/network/interfaces Findwlan0, add belowwireless-power off, after adding save and reboot the systemsudo reboot.After rebooting, open the terminal, enteriwconfig, you will find that power-saving mode has been disabled.(Tip: The above settings are not applicable to ubuntu-mate system. The specific solution is shown in the figure below.)

At this point, you have completed the basic setup of MagicMirror.

Next, create a usable configuration file for testing. Inside the MagicMirrorconfig folder:

pi@magicpi:~ $ cd MagicMirror/config
pi@magicpi:~/MagicMirror/config $ cp config.js.sample config.js

Try to start MagicMirror:

pi@magicpi:~/MagicMirror/config $ cd $HOME/MagicMirror
pi@magicpi:~/MagicMirror $ npm start

If all goes well, your display will show the MagicMirror interface. The weather module may prompt you that there is no valid APPID, but after simple setup it will look like the picture below:Finally, complete your smart mirror according to the above steps, as shown in the picture below.Perfect! Your Raspberry Pi smart mirror has been successfully created! Congratulations~
