Special Blocks

The Special section provides blocks that allow you to add structure, timing, and event-driven behavior to your scripts. With these blocks, you can:

  • Define how often and how many times your main code should run.

  • Keep track of each execution cycle, allowing you to respond differently as a task progresses.

  • Receive and handle incoming messages from an MQTT broker, as well as send messages and data out, enabling real-time communication and interaction with other devices or services.

By using these Special blocks, you can create dynamic, event-responsive, and time-aware scripts that are well suited for a wide range of IoT scenarios.

task

Defines the primary execution loop for your script.

Parameters

  • Number of Executions (Number): 0 for infinite.

  • Frequency (Number, ms): Delay between executions.

task pass

Returns iteration information about the current task execution.\

Returns

  • Number: -1 if infinite; otherwise a countdown from n-1 to 0.

NOTE: An iterator can not be used outside the task.

is event

Checks if an event with a specified name has been received from the MQTT broker.

Parameters

  • Event Name (String)

Returns

  • Boolean: true if the event is present, false otherwise.

pop event

Retrieves and removes the value associated with a specified event from the MQTT broker.

Parameters

  • Event Name (String)

Returns

  • Any type: The value associated with that event.

push event

Sends an event with a value to the MQTT broker.

Parameters

  • Event Name (String)

  • Value (Number, Boolean)
