UPDATE 31.10.: Amazon Alexa - ioBroker Skill läuft aus ?

[Heimweh]

@martin_olw Ich hab es jetzt doch getestet und noch was geändert:

Hier die Beschreibung:

Der Skript überwacht den Datenpunkt alexa2.0.Lists.SHOP.json.

Sobald Alexa z. B. sagt:

„Alexa, setze vier Äpfel auf die Einkaufsliste“
wird das als neuer Eintrag in dieser Liste erkannt.

Zahlwort-Umwandlung:

Aus „vier Äpfel“ wird „4 Äpfel“.

Auch zusammengesetzte Zahlen wie „fünfzehn“ oder „dreiundzwanzig“ werden korrekt erkannt.

Das erste Wort nach der Zahl wird großgeschrieben: z. B. „4 Äpfel“ statt „4 äpfel“.

Todoist-Eintrag:

Der bereinigte und umgewandelte Eintrag wird direkt über die REST-API an Todoist gesendet und dort im definierten Projekt als Aufgabe eingetragen.

Automatisches Entfernen in Alexa:

Nach 60 Sekunden wird der passende Alexa-Listeneintrag automatisch als „abgehakt“ markiert.

Es muss nur die ListID und der Token eingesetzt werden.

const axios = require('axios');

// Todoist API-Konfiguration
const todoistProjectId = 'XXXXXXXX'; // Deine Projekt-ID
const todoistToken = 'XXXXXXXXXXXXXXXXXXXXXXX'; // Dein Token

let previousList = [];

// 1. Alexa-Änderungen überwachen
on({ id: 'alexa2.0.Lists.SHOP.json', change: 'any' }, function (obj) {
    try {
        const currentList = JSON.parse(obj.state.val);

        if (currentList && currentList.length > 0) {
            if (previousList.length < currentList.length) {
                const newItem = currentList.find(item =>
                    !previousList.some(prevItem => prevItem.id === item.id)
                );

                if (newItem) {
                    const umgewandelt = wordsToNumbersSmart(newItem.value);
                    const aufgabe = capitalizeFirst(umgewandelt);
                    addTaskToTodoist(aufgabe);

                    // Nach 60 Sekunden Alexa-Eintrag auf "completed" setzen
                    setTimeout(() => {
                        const alexaList = JSON.parse(getState('alexa2.0.Lists.SHOP.json').val);

                        const matchingItem = alexaList.find(item => {
                            const itemText = wordsToNumbersSmart(item.value).trim().toLowerCase();
                            return itemText === aufgabe.trim().toLowerCase();
                        });

                        if (matchingItem) {
                            const completeState = `alexa2.0.Lists.SHOP.items.${matchingItem.id}.completed`;

@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.

[elron]

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.

[Sil4s]

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,

@elron
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.
 *
