Complete follow script


Copy this basic Python script for your Iotic Things, and save it as a .py file.


It will perform some of the basic functions you may want your Iotic Thing to perform, including receiving data and printing essential details. You can find more information about these functions in the following sections.


Simply run the script from a terminal using python3 and you will begin to receive data from the Things you follow. The data is event-driven, so as soon as it’s published, you’ll receive it.


Illustration of the Iotic folder-file structure


NOTE: This script references a Thing with the Local ID First_Iotic_Thing, and the file Iotic_Agent.ini. You will need to update these to match your own Thing Local ID and the name of your .ini file.

Remember, before you can hook your Thing up to code you also need to:


  1. Create a new Iotic Agent in the Space app, and download an .ini file
  2. Assign Things to an Agent
  3. Organise your file directory
