HomeAssistant Setup for Google Music

1. Place the files under homeassistant_files in the config directory of your Homeassistant machine.
2. You will need to create custom_components/switch directory in your config directory and place gmusic.py in there.
3. Follow this forum post to install gmusicapi, find your device id, and set up the component.

Links to items needed:

• 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 I have Home Assistant running in a Virtual Machine on another computer. If you want to run Home Assistant and the music cards on the same machine I'd recommend a Raspberry Pi 3 as opposed to the Raspberry Pi Zero
