Hello everyone! I wanted to share my recent project integrating Homematic and Hue devices, which has been a fantastic journey. 
The Setup
I’ve always been a fan of Hue lights for their vibrant colors and smooth dimming. However, I wanted the convenience of controlling them via traditional Homematic switches. My goal was to create a system where pressing a light switch would adjust the Hue lights according to a predefined scene.
The Process
Here’s what I did:
- Hardware Installation: I installed Underputz actuators in each light switch box. These are always ‘on’, providing power to the Hue lights.
- Switch Integration: I used Homematic wall switches to send signals to my Raspberry Pi running Deconz.
- Software Magic: I set up a custom CCU add-on to translate the switch signals into commands for Deconz, which then communicates with the Hue lights.
Challenges and Solutions
Initially, I faced some latency issues. To address this, I optimized the signal processing in the add-on. It’s crucial to ensure smooth transitions without any noticeable delay.
Success Story
The result? Seamless integration! Pressing a switch now adjusts the Hue lights exactly as intended. It’s like having the best of both worlds—traditional switches with modern smart lighting.
Tips for Others
- RaspberryMatic + DeconZ: Running both on the same Pi streamlines communication.
- Latency Check: Test your setup to ensure there’s no delay in response.
- Scene Programming: Spend time setting up scenes to match your lifestyle—whether it’s a cozy evening or bright mornings.
Final Thoughts
This project has been incredibly rewarding. It’s amazing how technology can blend the old and new to create something truly functional and beautiful. If anyone has similar projects or questions, I’d love to hear about them! 
Happy smart home tinkering!
