Spotify Now Playing

A React app meant for a Raspberry Pi Zero 2 W with a Hyperpixel 4.0 Square display.

Example screenshot

Architecture

The React app can be hosted either directly on the Pi, or somewhere else.

When not playing a clock is shown, and when enabled a request will be made to the local Pi to turn the screen on and off.

Occupancy detection can also be enabled, where a Home Assistant entity state will be queried. When the entity is off, the screen will be turned off.

Unfortunately due to cross-origin request issues TLS will most likely need to be enabled on everything.

Setup

Session autostart

Place contents of autostart in .config/lxsession/LXDE-pi/autostart, which will call autostart-spotify-playing.sh. This will hide the cursor, disable the screensaver and power management, and start Chromium in kiosk mode after a delay to so the URL actually loads.

Screen handling

screen.php will need to be hosted on the Pi, and the URL added to your .env.production. It calls screen.sh, which the www-data user needs to call with sudo so the script has access to your user's .Xauthority file.

Create /etc/sudoers.d/screen containing

www-data ALL=(ALL) NOPASSWD: /root/screen.sh on, /root/screen.sh off

Occupancy

Add a Home Assistant boolean entity to your .env.production. For example, I have a helper entity that I toggle with a "when people are home" automation in HomeKit which is named input_boolean.homekit_occupied.

You will have to enable CORS in your Home Assistant configuration for the domain the React app is running on.

  cors_allowed_origins:
    - http://localhost:5173
    - https://spotify-playing

Helpers

It may be helpful to use xdotool to reload Chromium without needing to VNC into the Pi. An example is the reload-chromium.sh script.
