Freezer Content -- Home Assistant

This repository contains configuration files and dashboards for managing a freezer ("Gefriertruhe") in Home Assistant.
It includes: - Complete configuration (gefriertruhe.yaml) - A Lovelace dashboard example (dashboard.yaml) - An experimental web barcode scanner (scanner_20.html) as an add-on

---

📦 Installation (Gefriertruhe)

1. Add helpers and scripts

Copy the content of gefriertruhe.yaml into your Home Assistant configuration.yaml, or split it into your existing structure.
This will install: - Helpers (input_number, input_text, input_select) - Script to add freezer entries and increase IDs -

(Optional) Webhook automation for barcode scans

Restart Home Assistant after saving changes.

---

2. Dashboard setup

The supplied dashboard.yaml contains a Lovelace grid layout with: - To-do list for freezer items - Helper controls - Last scanned barcode

⚠️ Note: Lovelace dashboards cannot be defined directly in configuration.yaml.
Import this file via the Dashboard Editor or use YAML mode with a separate file.

🧪 Experimental: Web Barcode Scanner

The file scanner_20.html provides a QR/Barcode scanner that runs in the browser.
It is experimental and meant as an add-on:

• Uses your device (i.e. handy) camera to scan codes
• Can send results directly to Home Assistant via Webhook
• Includes optional product lookup using Open Food Facts
• Beware: only webhook is tested ....
• also browsers may only allow camera usage when using https://

Usage

1. Copy scanner_20.html into your Home Assistant www folder:

   config/www/scanner.html
   

2. Access it from your browser via:

   https://<your-ha-url>:8123/local/scanner.html
   

   or using the buttons already placed in the dashboard (check the link if it's apropriate for you environment).

3. Configure the webhook endpoint inside the UI.
   (By default, it expects the barcode_scan_p webhook from the Gefriertruhe config.)

⚠️ Notes

• The scanner is experimental, some devices/browsers may not support all features (e.g. torch). - tried with Laptop, Moto 50 Handy, Samsung Flip Handy. - is not running on some fires with missing auto focus
• You can extend the food list in input_select.speisen with your own entries.
• The todo.gefriertruhe_2 entity in the config must match your own To-do list integration. https://www.home-assistant.io/integrations/local_todo/
