Raspberry PI Scan Station for Speisekammer.App

Tested with:

• Raspberry PI 3B
• Raspbian PI OS (Debian Bullseye)

Right now just supports one specific USB scanner, needs more work to be more generic.

Perform the following steps to get it running:

• Create an SD Card with "Raspberry PI Imager", choosing Raspberry PI OS. I chose the lite image without a desktop.
• Connect to your PI using SSH or a monitor and keyboard
• Download this repo to you Raspberry PI: git clone https://github.com/speisekammer/raspi-scan-station
• cd raspi-scan-station
• pip install evdev requests ujson
• Get a Speisekammer.App API key from here: https://app.speisekammer.app/developer
• Create a config file named config.json with your account data:

{
  "token": "your_api_key",
  "communityId": "your_community_id",
  "storageLocationId": "your_storage_location_id"
}

• Print a sheet with the "INSERT" and "REMOVE" barcodes, located in doc/Speisekammer.App Scan Station.pdf
• Run the scanner script: python scanner.py
