Introduction
Some of the most interesting technology projects are the ones that combine imagination with engineering.
The Model TARDIS project started as a fun idea: take a physical model and bring it to life using modern automation technology.
By combining Raspberry Pi, Node-RED, MQTT and Home Assistant, the goal was to transform a static display into an interactive smart device.
The Idea
The aim was to create a model that could:
- React to events
- Control lighting
- Play sounds
- Run scheduled sequences
- Integrate with the wider smart home
Rather than being a simple display, the TARDIS becomes another connected device within Realm Labs.
The Hardware
The project uses a Raspberry Pi as the controller.
The Pi provides:
- Network connectivity
- Automation control
- Communication with other services
- Hardware interfaces
This makes it an ideal platform for custom projects.
Connecting the Software
The project combines several technologies already used throughout Realm Labs.
Home Assistant
Provides the central automation platform.
Node-RED
Handles more complex sequences and logic.
MQTT
Provides communication between systems.
This creates a flexible architecture where each part has a specific role.
Automation Sequences
The fun part of the project is creating behaviours.
Examples include:
- Scheduled activation
- Lighting effects
- Sound effects
- Event-based triggers
- Interactive controls
A simple automation can become a complete sequence:
Trigger Event

Node-RED Logic

MQTT Message

Why Projects Like This Matter
Not every project needs to solve a business problem.
Creative projects are often where the best learning happens.
This project combines:
- Programming
- Networking
- Electronics
- Automation
- User experience design
It demonstrates how different areas of technology can come together.
Lessons Learned
Building physical automation projects introduces challenges that don’t always appear in software-only projects.
Things to consider include:
- Reliable hardware control
- Timing accuracy
- Power management
- Communication reliability
- Physical installation
The process is just as valuable as the final result.
Future Improvements
Future ideas include:
- More lighting effects
- Additional sensors
- Voice control
- AI integration
- More advanced automation sequences
Conclusion
The Model TARDIS project represents what Realm Labs is all about.
It combines technology and creativity to create something unique.
A home lab is not only about servers and networking — it is also a place to experiment, build and have fun.
