Hello everyone, I wanted to share my recent DIY CCU project with you. It’s been a fascinating journey, and I hope it can inspire others, especially those new to the world of smart home automation. **
The Core of the Project:
I started with a Raspberry Pi 3, which serves as the foundation of this CCU. It’s a fantastic little device that packs a punch for its size. **
Storage Solution:
For the micro SD card, I opted for the SanDisk Ultra series, which has provided reliable performance. Of course, there are plenty of other options out there, so feel free to explore what works best for you! **
Power Supply:
A high-quality USB power adapter that delivers 2A is essential. I chose one that not only powers the Raspberry Pi but also ensures stability for the entire setup. **
The Wireless Module:
This was the most exciting part of the project. I sourced a Funkmodul from ELV, which, after some soldering, became the backbone of my CCU. If you’re not confident in your soldering skills, don’t worry—many local electronics shops can help you with that. **
Enclosure:
To give my project a polished look, I selected an Orbital Case for the Raspberry Pi. It’s sleek, space-efficient, and best of all, it keeps everything neatly organized. **
Cost Breakdown:
- Raspberry Pi 3: ~€35
- micro SD Card: ~€8
- Power Adapter: ~€13
- Funkmodul: ~€20
- Enclosure: ~€18
Total hardware cost came to around €94, which is surprisingly close to the price of a commercial CCU2. While it doesn’t save you a significant amount of money upfront, the benefits are undeniable. The performance is leaps and bounds ahead of a standard CCU2, especially as you expand your smart home setup with additional devices. **
Software Choices:
I explored several options and settled on YAHM (Yet Another Homematic), which aligns with my preference for a more open and customizable system. However, I would recommend RaspberryMATIC for those new to Linux, as it offers a smoother setup process. **
Future Enhancements:
This is just the beginning! I have a few more components in mind to take this project to the next level. I’m particularly excited about integrating a UPS (Uninterruptible Power Supply) to ensure uninterrupted operation, even during power outages. Stay tuned for more updates as I continue to refine this DIY gem. **
Final Thoughts:
This DIY CCU project has been a rewarding experience, blending creativity with practicality. It’s a testament to how much you can achieve with a bit of research, some tools, and a willingness to learn. I’m thrilled to share this with the community and look forward to hearing about your projects too! Happy tinkering!
