ECMA 2021 script - Motion Sensor On/Off delay switch lights OFF

Setup, Configuration and Use Scripts & Rules
1

Working ECMA 2021 script.

  • Define ItemNames for variable ItemToSwitch and MotionSensor.
  • Trigger should be when you motion sensor change its state.

//var ScriptExecution = Java.type("org.openhab.core.model.script.actions.ScriptExecution");

// Timer delay value minutes
var TimerMinutes = 3;
// Init timer if not already active
this.timer = (this.timer === undefined) ? null : this.timer;

// Item name in registry to switch
var ItemToSwitch = 'Steckdose_F_schalter';
// Motion Sensor name in registry that detects motion
var MotionSensor = 'IKEABewegungmelder1_Bewegung'

// Will be called when timer reached the timer delay value of TimerMinutes
