Time Delay , Generic Power Switch script

#1

Hi ,
Is it possible to add time delay when I turn ON or OFF a generic power switch ? For example I want to press ON the switch and the connected Relay will be ON and after a few seconds OFF.
Can I have an example of the script please ?

Thanks !

You can use a Timer for that.

ThingEvent {
  thingId: "..." // Some button
  eventName: "pressed"
  onTriggered: timer.start()
}

Timer {
  id: timer
  interval: 5000
  onTriggered: light.value = true
}

ThingState {
  id: light
  thingId: "..." // some light
  stateName: "power"
}

Here are the docs for the timer: Timer QML Type | Qt QML 5.15.8

actually, if you just want to add a auto-off to a light you might also just do something like this:

ThingState {
  id: light
  thingId: "..." // some light
  stateName: "power"
}

Timer {
  interval: 5000
  running: light.value === true
  onTriggered: light.value = false
}

This would now auto-start the time every time the light goes on and turn it off again after 5 seconds, regardless of how the light was turned on (either via app, or some other rule, or anything else).
