Neuer ioBroker-Blog online: Monatsrückblick März/April 2026

Node.js : v14.19.0
js-controller 3.3.22
Javascript v5.2.21

Zur Simulation sollten alle 2 Sekunden Werte im Bereich 400 - 450 bzw. 14000 - 16000 geschrieben werden.

Code dazu :

Spoiler

var bool, Intervall, Intervall2;

function mathRandomInt(a, b) {
 if (a > b) {
   // Swap a and b to ensure a is smaller.
   var c = a;
   a = b;
   b = c;
 }
 return Math.floor(Math.random() * (b - a + 1) + a);
}


while (!bool) {
 if (getState("0_userdata.0.Testsystem.Boolean").val) {
   Intervall = setInterval(async function () {
     setState("0_userdata.0.Testsystem.Number"/*Number*/, (mathRandomInt(400, 450)));
     console.log(getState("0_userdata.0.Testsystem.Number").val);
   }, 2000);
 } else {
   Intervall2 = setInterval(async function () {
     setState("0_userdata.0.Testsystem.Number"/*Number*/, (mathRandomInt(14500, 16000)));
     console.log(getState("0_userdata.0.Testsystem.Number").val);
   }, 2000);
 }
}

Das führt aber wiederholbar zu m Absturz der JavaScript Instanz.

Könnte mir bitte jemand sagen wie ich das besser machen kann. Vielen Dank !

Was besser machen …

• Das ‘wiederhole solange’ weg.
• um das ‘falls Wert’ einen Baustein aus dem trigger Bereich legen, trigger auf den gleichen datenpunkt, wurde geändert
• vor dem falls noch ein ‘anhalten intervall’ und ein ‘anhalten intervall2’ und es sollte gut aussehen.

@asgothian

vielen Dank, so läuft das. Per Schleife immer neue Intervalle zu erzeugen bringen das Fass zum überlaufen.

.. glaube ich hab's :-)
