Event Basics

Introduction to Events

Events in Twidget are fundamental building blocks that allow you to automate tasks on a schedule. These events trigger at specified times or at recurring intervals, executing a predefined list of commands without the need for any inputs or outputs.

Types of Scheduled Events

1. One-Time Events: These events are scheduled to occur at a specific date and time.

2. Recurring Events: These events trigger at regular intervals, e.g., every hour, day, week, etc.

How Events Work

• Schedule: Define when the event should trigger. This could be a specific date and time or a recurring interval.

• Commands List: Specify the sequence of commands that the event should execute. These commands are run in the order they are listed.

Creating an Event

1. Define the Schedule: Set the exact time or recurring interval for the event.

2. Add Commands: List the commands to be executed by the event.

Characteristics of Events

• No Inputs/Outputs: Events do not require any inputs to trigger and they do not produce outputs. They are based purely on the schedule and execute the commands listed.
