ESPHome components for USB Keybord/ USB Barcode Scanner and a Paprika2App Component

This repository contains external components for ESPHome

USB Barcode Scanner or Keyboard Component

This component enables keyboard or barcode scanner connected via USB OTG port of ESP32 S2/S3 family of micro-controllers. Additionally the component can resolve the pure barcode into a food product name.

Paprika3App Component

This component allows to add items to the Paprika3App grocery list.

Memory, PSRAM

The Paprika3App component requires a lot of memory to gzip requests (Sadly needed by the weird API). Thus, the ESP32-S2/S3 device has to have PSRAM connected and enabled, e.g.:

psram:
  mode: octal
  speed: 80MHz

ESP-IDF framework mode

Arduino framework is not supported. And flash mode must be corrected for esp-idf ESP32 S2/S3.

esphome:
  platformio_options:
    board_build.flash_mode: dio  # default mode is wrong

esp32:
  board: esp32-s3-devkitc-1
  framework:
    type: esp-idf

Import external components

The following yaml can be used to import components into your ESPHome configuration:

external_components:
  - source: github://danielBreitlauch/esphome_components

Enable barcode scanner

text_sensor:
  - platform: usb_barcode_scanner
    name: barcode
    type: food                # optional 'barcode' will show the barcode or 'food' (default) will show the product name
    openfoodfacts_region: de # optional specify the region for lookup queries to OpenFoodFacts. Default: world

Enable Paprika3App

paprika-app-list:
  email: "xxx"      # login email of the apps account
  password: "xxx"   # login password of the apps account
  listID: "xxx-xxx-xxx-xxxx-xxxxxxx-xxxx-xxxxxxxxxxxxx" # listId of the grocery list lmk if it needs to be simpler to find this

Action to add something

text_sensor:
  - ...
    on_value:
      then:
        - paprika-app-list.add
            format: "lala: %s"    # Optional: formats the incoming text
