🚀 From a Semester Project to a Real-World IoT Platform: My Journey with Alpha Connect Hub

🛠️ The Beginning: A Surprise Assignment

In my fifth semester—right after summer break, when I had built up my web development stack and started exploring project ideas—our university web programming professor gave us a new assignment.

The task? Build a web app that displays and logs real-time data from IoT devices.

This wasn’t something I was familiar with. I had worked on web apps but had no experience connecting them to hardware or handling real-time data streams from sensors.


🌐 My First Big Question: How do sensors talk to servers?

With some basic understanding of ESP32, Arduino, and gateways, I started thinking:

  • How does sensor data get from the device to a web app?
  • Why don’t we question protocols enough as CS students?

I was used to HTTP/HTTPS. But sensors? That was a whole different story.


🔍 Enter MQTT: The Game Changer

While digging deeper, I discovered MQTT (Message Queuing Telemetry Transport)—a lightweight messaging protocol perfect for IoT.

Once I understood how it works, the next challenge was configuration.

I wrote the code to handle publishing and subscribing to topics, and learned how devices constantly send data in real time.


⚠️ CaaS Challenges and Broker Setup

I initially ran my server using Node.js and deployed it via CaaS (Container as a Service). But that raised questions:

  • What happens if the server goes idle or shuts down due to CaaS policies?
  • How is device authentication handled in MQTT?

Turns out, MQTT brokers need usernames and passwords for each device, which isn’t easy to manage with dynamic web apps running in containers.


☁️ My Solution: EMQX + Virtual Machines

So, I searched for an open-source MQTT broker and chose EMQX.

To avoid CaaS limitations, I hosted it on Ubuntu 22.04 LTS VMs, giving me full control.

This hands-on process also introduced me to tools like:

  • Azure IoT Hub
  • HiveMQ Cloud
  • ThingSpeak

✅ The Result: Alpha Connect Hub

After days of deep work and debugging, I finally saw real-time sensor data from an ESP32 device displayed on a secure, session-managed, dashboard-equipped web app.

That app became Alpha Connect Hub—a flexible, scalable system that now forms the foundation for my ongoing exploration of the IoT world.


💡 What I Gained

  • Real-world exposure to protocols, deployment, and cloud limitations
  • Hands-on understanding of IoT architectures
  • The confidence to build and scale real solutions, not just class projects

🎯 This project didn’t just get me marks—it gave me a mission.


🤝 Let’s Connect

I’d love to connect with others exploring IoT, MQTT, full-stack architecture, or real-time systems.
