Requires

software:

• python evdev. To install:

wget http://dl.piwall.co.uk/python-evdev_0.4.1-1_armhf.deb

dpkg -i python-evdev_0.4.1-1_armhf.deb

• python mpd-2. To install

pip install python-mpd2

hardware:

• Raspberry Pi Zero (Don't forget micro sd card and power supply)
• USB OTG Hub
• RFID 125Khz Reader
• 125Khz Cards
• RFID Card Inkjet Tray to print in your printer (Note this is the model needed for my Canon MX922 Printer)

Please note that Raspberry Pi Zero is insufficient to run both the Home Assistant and Music Cards concurrently. I recommend you use a Raspberry Pi 3 if you intend to run both at the same time.

Steps to Configure and/or Run once if you dont want Music Cards to AutoStart

1. Run python config.py to select the reader from the inputs
2. Run python add_card.py to scan cards and enter your Google Play Music Playlist Name
3. Run python box.py to start the application and verify that it is reading your cards and csv list properly

Install Service to AutoStart

• Change directory to music-cards/

cd music-cards/

• Copy the musiccards.service file to systemd

sudo cp musiccards.service /etc/systemd/system/musiccards.service

• Reload the Daemon

sudo systemctl daemon-reload

• Start the musiccards.service

sudo systemctl start musiccards.service

• Check if musiccards.service is running

sudo systemctl status musiccards.service

HomeAssistant Setup for Google Music

1. Place the files under homeassistant_files in the config directory of your Homeassistant machine.
