vacation ghost script/plugin

[paede]

Hi all
I'm looking for a script or plugin that does something like this:

(this text is from a vera plugin i used to have)
This plugin allows you to let lights be turned on and off automatically/randomly when you are in vacation or absent. It allows you to define in how many times in which phase it should turn on lights and how long they are supposed to be running on which level. Based on variables you define the plugin does all the calculations itself. These ghost a generated newly in every phase, so on each day the times when a light turns on and how long it stays on will vary.

I tried to code it in blockly, but could not do it.

Did someone write such a script?

greets

Hello,
Why not use the blockly "set...=...Rndomwithin...minutes ?
This is how is solved it for holiday / away mode
