The core idea of the Internet of Things is to have small computing devices which provide a specific, targeted interface to some thing or event or device. The small computing device collects measurements of various kinds and/or it is used to modify the state of the thing or event or device.
A specific example is an automated weather station in which a small computing device has various sensors attached and the computing device samples the sensors and collects the various measurements reported by the sensors and then provides those measurements to some other device.
Another would be an automated digital camera that is set up so that when wildlife passes by the camera takes photographs and then sends the photographs to some of device for processing or review.
What you have done is no different than what could be done and often is done with a standard workstation. It is not really an Internet of Things application as something similar is available on my Windows 10 desktop computer for instance.
I will tell you what I am doing with my Raspberry Pi.
My first application was something exactly like what you describe, PiClock is the actual application and the source code is available on the internet. It display an analogue clock along with weather forecast and driving conditions.
The next thing I did was to purchase an Osoyoo Raspberry Pi Starter Kit from Amazon. This kit contains a variety of components, sensors, a servo motor, etc. and the manufacturer has projects that start off simple on their web site. I am using this to learn the basics of electronics for IoT devices.
I have started a GitHub repository so that I can keep my notes and source code in a safe place. https://github.com/RichardChambers/raspberrypi/
Once I have gained some degree of knowledge concerning the electronics of IoT I am going to take a look at some of the projects that others have done and give one a shot.
Here is a list of resources on IoT projects for Raspberry Pi:
