Application settings

The web interface under Settings contains:

• Interface language
• Home Assistant URL, token, and shopping-list synchronization
• Visibility of products with zero stock
• Backup actions
• Software update status and manual update check
• Optional user accounts, roles, NFC cards, and scanner sign-in policy

User accounts and the stricter scanner policy are both disabled by default. See User accounts and NFC.

See Updates before enabling Docker-based installation.
