[SOLVED] Turn item on at random time between a certain time

[diado (jando)]

Hello all,

i use openhab3.
Now i have 2 rules, one turns a light on and the other is turning the light off.
Now i would like to change the rule so that the light is turned on between 8:00 and 9:00 but at a random time so that it turns on at different time everyday.
Is this possible?
I am using the GUI.

If this is not possible, is there a other way of doing this?

Did you search the community? Because “trigger random” gave me this:

Trigger actions on random basis between certain time frame

I was looking around in java and there is a possibility to create random numbers. the code below is working and is created for testing purposes. I’ve put it here perhaps it could be interesting for others. It is just triggered every minute and then a random timer is triggered to send a command to a wall switch toggling on off wich is controlled by the boolean onoff. import java.util.Random; var boolean onoff = false rule "TestRandomOn" when Time cron "0 0/1 * 1/1 * ? *" // every…

I have no idea if it works in OH3, though.

Thanks for the reply.

Yes i did, but cant find anything with OH3 with the use of the UI.

Anything that can be done with a rule in OH2 should be doable in OH3 (possibly requiring some tweaks). Just insert the “then” portion of the OH2 rule into your UI rule as a script.

Thanks for the reply.

Then i should get this working.
