Hi Dirk,

This is how I do it:

items:

Group Lights_Random

rules:

var Timer tRandomLights = null

rule "Randomly turn on & off lights between 07.00-23.00 if before or after sunset and if alarm is activated"
	when
		Time cron "0 */10 7-23 * * ?"
	then
		if ((AlarmMode.state == 2) && (now.isBefore((Sunrise_Time.state as DateTimeType).calendar.timeInMillis) || now.isAfter((Sunset_Time.state as DateTimeType).calendar.timeInMillis))) {

			// Only turn a light on/off ocasionally
		 	if ((new java.util.Random).nextInt(2) == 1) { 
		 	
		 		// Create a timer with a random value
				var int randomTime = (new java.util.Random).nextInt(300)
				logInfo("org.openhab","Setting random lights timer to " + randomTime + " seconds.")
				tRandomLights = createTimer(now.plusSeconds(randomTime)) [|
					var randLightIndex = (new java.util.Random).nextInt(Lights_Random.members.size)
			 		var randLightStateCurrent = Lights_Random.members.get(randLightIndex).state
			 		var randLightStateNew = if (randLightStateCurrent == ON) OFF else ON
			 		logInfo("org.openhab","Switching light " + Lights_Random.members.get(randLightIndex).name + " from " + randLightStateCurrent + " to " + randLightStateNew)
			 		sendCommand(Lights_Random.members.get(randLightIndex), randLightStateNew)
		        ]
			}
		}
end

rule "Turn all lights off at 23.10 if alarm is activated"
	when
		Time cron "0 10 23 * * ?"
	then
		if (AlarmMode.state == 2) {
		 	logInfo("org.openhab","Turning all the random lights off.")
		 	sendCommand(Lights_Random, OFF)
		}
end

Hope it helps :smile: Let me know if you have any questions.
