Alexa Shopping List mit Bring synchronisieren

no6mis

@heimweh, danke für das Script, endlich kann man die Einkaufsliste in Alexa wieder benutzen.

previousList = currentList;

sollte allerdings außerhalb des if-Zweigs gesetzt werden, ansonsten gibt es ein Problem, wenn man die Liste in der Alexa-App leert. Dann wird beim nächsten Aufruf die previousList mehr Inhalte haben als die currentList und die folgenden Einträge bis zum Neustart des Scripts oder bis die aktuelle Liste wieder einen Eintrag mehr hat als die vorherige Liste nicht mehr hinzugefügt.

Damit das hinterlegt Script Stand 11/2025 wieder funktioniert, muss hier die Alexa Object-ID geändert werden
von

/*---------- OBJECT-ID CONSTANTS ------------------------------------------------------------------------------------------------*/
const objectID_alexa_shoppingList_folder = 'alexa2.0.Lists.SHOPPING_LIST';
const objectID_alexa_shoppingList_addItem = 'alexa2.0.Lists.SHOPPING_LIST.#New';

auf

/*---------- OBJECT-ID CONSTANTS ------------------------------------------------------------------------------------------------*/
const objectID_alexa_shoppingList_folder = 'alexa2.0.Lists.SHOP'; 
const objectID_alexa_shoppingList_addItem = 'alexa2.0.Lists.SHOP.#New';

Andernfalls erhält man die 2 Fehler

script.js.Bring-Alexa-Sync: Cannot read properties of undefined (reading 'val') und script.js.Bring-Alexa-Sync: TypeError: Cannot read properties of undefined (reading 'stopScriptAsync')

Kannst du bitte auf das originale Script verlinken? Ich finde es hier leider nicht.
Danke für die Anpassung.

Danke an alle für diese tolle Lösung. Ich hatte nur das Problem, dass das sync script alle 2 Minuten Änderungen erkannt hatte, obwohl sich nur das Update Date geändert hatte. Ich habe keine Sachen in Bring oder Alexa hinzugefügt/gelöscht. Daher wollte ich unnötige updates der Listen vermeiden und habe das Skript für mich wie folgt angepasst.

Danke, hatte auch die regelmäßigen Aktualisierungen.
Hab mal auf deine geänderte Version umgestellt. Bisher schaut alles gut aus!

Danke dafür!

@Oreider Super das freut mich, bei mir läuft es auch stabil und meine Frau hat auch noch nicht gemeckert. :)

Hi Martin,

Der Link funktioniert leider nicht (zumindest bei mir). Ich habe das Script von @sil4s genommen.

Okay, komisch, hier nochmal der gesamte Code inkl. der aktuellen Änderung:

/***********************************************************************************************************************************************************************************
 * GENERIC INFO:
 *      Created by Daniel Drießen @ DDProductions
 * 
 *      Date of creation:   17.07.2024
 *      Version:            0.1.0.0    
 * 
 * DESCRIPTION:
 *      This script synchronizes the shopping lists of 'Alexa' and 'Bring'.
 *      It monitors changes in both shopping lists and ensures that they stay updated with each other.
 *      The script uses events to detect changes in the shopping lists of both 'Alexa' and 'Bring'.
 *      When changes are detected, it initiates a synchronization to reconcile any discrepancies between the lists.
 *      The synchronization process involves comparing the items on both lists and updating each list to reflect the combined items from both sources.
 * 
 * DEPENDENCIES:
 *      - Alexa2 adapter
 *      - Bring adapter
 *
 * LIMITATIONS:
 *      Due to the nature of the 'Bring' adapter (which does not store an 'added' or 'updated' timestamp for items on the shopping list), a 'real' synchronization is not possible
 *      because there is no way to detect the order of changes to the shopping lists of 'Alexa' and 'Bring'.
 * 
 * TODO & FUTURE GOALS:
 *      - Add better error handling.
 *      - Move functions 'getItemsOnAlexaShoppingList' & 'getItemsOnBringShoppingList' into classes 'AlexaShoppingList' & 'BringShoppingList'.
 *      - Move functions 'addItemToShoppingList', 'removeItemFromShoppingList' into classes 'AlexaShoppingList' & 'BringShoppingList'.
 *      - Enhance the synchronization logic to minimize potential syncing errors and improve reliability given the above limitations.
 *      - Maybe add a sync schedule for periodic syncing.
 * 
 * CHANGELOG:
 *      18.07.2024 - Initial version completed.
 *
