Hi Benjamin,

The solution you are looking for are scheduled events. These events are executed on set times, without any user interaction required.

You can add a new scheduled event by right clicking on a module name, and choose: “Add other → scheduled event” 

If you want the event to repeat on a regular basis, don't forget to set the repeat radiobox to yes.

Good luck!
