Setup for Raspberry Pi

WiFi

Please make sure you are connected to the 5 GHz frequency, and not 2.4 GHz. Also make sure the resolution is 1920x1080, since that impacts the speed of WiFi.

Plug in

Always plug in at HDMI 1

Access via SSH

Change hostname in: /etc/hosts and /etc/hostname

IP Address and password in 1Password

Use x11 instead of wayland

Use the raspi-config to update the window manager:

Troubleshooting

If only, there is no menu

You can simply restart the Raspberry Pi. Unplug it from the TV and back in or ssh pi@FIND-IP-IN-1PASSWORD sudo shutdown -r now

If the Raspberry Pi do not start

Unplug it from the TV and plug it in via HDMI 1 to another monitor. You can also plug in a keyboard and optional a mouse. When the Pi is started, you can exit the full screen with right click and click "exit full screen". After that, you can start the terminal.

Change your URL

You can change your URL and the scaling factor in .config/lxsession/LXDE-pi/autostart by changing this line

@chromium-browser --kiosk <YOUR-URL> -force-device-scale-factor=<SCALING-FACTOR>

Entrance Monitor

Runs Chomium in a restart loop. Reloads it every 5min.

# /home/pi/.config/lxsession/LXDE-pi/autostart
#!/bin/sh

Changing code

The raspberry pi is in read only mode thanks to overlayFs. If you want to make changes to anything(settings, scripts, etc.) you will need to disable overlayFS. You can do this after you SSH into the raspberry.

First you will need to open the config gui with:

sudo raspi-config

There you will go to the performance tab and disable the Overlay File system. Reboot the raspi with

sudo reboot

Afterwards you can SSH into it again and make your changes. Don't forget to enable overlayFs again after you made you changes as shutting down the raspi incorrectly would lead to data corruption otherwise.

Songs

The songs which are played when pressing the button are stored on Google drive

If you name a song lunch.mp3 it will be played at lunch time. Otherwise they will be played on random. The song script is saved in the home/pi folder. it is called script.py if you want to make changes.

Adding a new song to the folder will not make it available immediatly. The raspberry will only fetch the songs when it gets turned on. So if you want to make the songs available immediatly, reboot the device.

Changes to the fetching allgorithm can be made in the etc/systemd/system/fetch-songs.service
