json teilen

wendy2702

ein wenig Datenschutz muss sein

Magst du uns kurz erklären was das beantworten dieser Fragen mit Datenschutz zu tun hat?


Wie sieht das JSON aus?
Wie soll es dargestellt werden ?
welches widget hast du genommen ?
wie soll es dann aussehen ?

wolfgangkt

@wendy2702 das bezog sich auf die json Tabelle die ich nachträglich gekürzt habe

wendy2702

@wolfgangkt Und was steht da drin das dem Datenschutz unterliegt?

Mit unvollständigen Informationen/Angaben kann man nur schwer bis garnicht helfen.

@wolfgangkt Ich weiss ja nicht was für eine Logikmaschine du benutzt, aber wenn das ein Array von Objekten ist - dann greifst Du einfach über den Index zu.

var obj = JSON.parse('[{"Device":"Wassermelder Geschirrspüler","Adapter":"Zigbee","Battery":"100%","Signal strength":"100%","Last contact":"18:53 Uhr","Status":"Online"},{"Device":"Wassermelder Spüle","Adapter":"Zigbee","Battery":"100%","Signal strength":"100%","Last contact":"18:30 Uhr","Status":"Online"}]');

var teil1 = obj[0];
var teil2 = obj[1];
console.log(obj);

console.log(teil1);
console.log(teil2);

Sprich der Index Deines Objektes bestimmte die Zeilen und welche im Objekt. Sprich Du musst halt einen Pointer machen, der immer x Zeilen ausgibt.

Wenn Du halt 5 oder 6 Objekte in einem Array brauchst - dann läufst Du halt in einer Schleife da durch oder Du nutzt JSONATA und machst kleinere Arrays.

@mickym Danke. Ich poste nochmals den json-Datenpunkt. Und die ersten 30 Datensätze sollen in einen json-Datenpunkt geschrieben werden. Die Datensätze 31- xxx sollen dann in einen 2. json-Datenpunkt geschrieben werden. Und wie schon geschrieben mit meinen java Kenntnisse ist es nicht weit her.

@wolfgangkt sagte: die ersten 30 Datensätze sollen in einen json-Datenpunkt geschrieben werden.

Versuche mal:

const idJson = '...'; // Original
const idJson1 = '...'; // Teil 1
const idJson2 = '...'; // Teil 2

on(idJson, function(dp) {
    let arr = dp.state.val;
    const arr2 = [];
    for(let i = 30; i < arr.length; i++) {
        arr2.push(arr[i]);
    }
    arr.length = 30;
    setState(idJson1, JSON.stringify(arr), true);
    setState(idJson2, JSON.stringify(arr2), true);
});

EDIT: Zeilen 6 und 8 angepasst.

mickym

Ok dann bin ich raus. der Meister schreibt.

@paul53 Erstmal vielen Dank. Das Script läuft fehlerfrei durch aber es wird nichts geschrieben.

const idJson = 'device-watcher.0.zigbee.listAll'; // Original
const idJson1 = '0_userdata.0.Meine_Datenpunkte.Teil1'; // Teil 1
const idJson2 = '0_userdata.0.Meine_Datenpunkte.Teil2'; // Teil 2
 
on(idJson, function(dp) {
    let arr = JSON.parse(dp.state.val);
    const arr2 = [];
    for(let i = 30; i < arr.length - 30; i++) {
        arr2.push(arr[i]);
    }
    arr.length = 30;
    setState(idJson1, JSON.stringify(arr), true);
    setState(idJson2, JSON.stringify(arr2), true);
});

paul53

@wolfgangkt sagte: es wird nichts geschrieben.

Es wird nur bei Änderung im Original-JSON getriggert.

@wolfgangkt sagte: Unexpected token o in JSON at position 1

Das Original-JSON lässt sich nicht parsen, da es offenbar fehlerhaft ist.

wolfgangkt

@paul53 schade. Ich danke Dir trotzdem für deine Hilfe.

paul53

@wolfgangkt
Das JSON, das Du gepostet hast, lässt sich parsen. Teil 2 beginnt mit "Küchenfenster geschlossen".

wolfgangkt

@paul53 in dem Datenpunkt steht eigentlich immer das gleiche.
liegt es vielleicht an dem Datenpunkt selbst ?

{
  "type": "state",
  "common": {
    "name": {
      "en": "List of all devices",
      "de": "Liste aller Geräte",

      "nl": "List van alle apparaten",
      "fr": "Liste de tous les dispositifs",
      "it": "Elenco di tutti i dispositivi",
      "es": "Lista de todos los dispositivos",
      "pl": "Lista wszystkich urządzeń",
      "zh-cn": "所有装置清单"
    },

  }
}

paul53

@wolfgangkt
Der Datenpunkt ist vom Typ "array", kann also nicht geparst werden. Ändere Zeile 6 in

    let arr = dp.state.val;

wolfgangkt

@paul53 jetzt funktioniert es. Vielen Dank für die Hilfe

wolfgangkt

@paul53 zu früh gefreut. In den 2. Datenpunkt werden nur 3 Datensätze geschrieben.

paul53

@wolfgangkt sagte: In den 2. Datenpunkt werden nur 3 Datensätze geschrieben.

Ändere Zeile 8:

    for(let i = 30; i < arr.length; i++) {

wolfgangkt

@paul53 jetzt funktionierts. Besten Dank Dank nochmal.

haus-automatisierung

@wolfgangkt Hier noch eine etwas kürzere Alternative:

const idJson = '0_userdata.0.testjson'; // Original
const idJson1 = '0_userdata.0.json1'; // Teil 1
const idJson2 = '0_userdata.0.json2'; // Teil 2
  
on({ id: idJson, change: 'ne' }, (obj) => {
    const arr = JSON.parse(obj.state.val);

    setState(idJson1, JSON.stringify(arr.slice(0, 30)), true);
    setState(idJson2, JSON.stringify(arr.slice(30)), true);
 });
