Arduino and IR Receiver Integration with Vera: A Smooth Experience

Hey everyone, I wanted to share my recent project integrating an Arduino Uno with an IR receiver to control my Vera system. It’s been a fascinating journey, and I thought I’d walk through my experience in case anyone else is looking to do something similar.

So, the goal here was to overcome a limitation I was facing with my Harmony remote. It could only control single lights, not entire scenes on Vera. After some research, I stumbled upon a guide that suggested using an Arduino Uno and an IR receiver to capture IR commands from the Harmony and send them to Vera via Ethernet. Intrigued, I decided to give it a shot.

Hardware Setup
I started by gathering all the necessary components: an Arduino Uno, an Ethernet shield, an IR receiver, a power supply, and some jumper wires. The setup was pretty straightforward. I attached the Uno to the Ethernet shield, wired up the IR receiver, and powered everything up. The hardware portion was done in no time—just a matter of plugging in the components.

Software Configuration
Next came the software part. I installed the Arduino IDE and started working on the code. The code was designed to capture IR commands from the Harmony, convert them into HTTP requests, and send them to Vera to trigger specific scenes. I used an HK AVR114 for the IR commands since it was readily available.

One thing I found particularly interesting was the versatility of the setup. I could assign different IR codes to various scenes. For example, the ‘Up’ button on my Harmony was set to trigger scene 14, while the ‘Down’ button triggered scene 4. This allowed me to control multiple lights or devices with a single press, which was exactly what I needed.

Testing and Tweaking
After uploading the code to the Arduino, I tested it by sending IR commands from my Harmony remote. It worked like a charm! The Vera system responded promptly, and the scenes were triggered without any hiccups. I even added some delay commands to ensure smooth operation.

One minor downside I noticed was that the system required an activity page to be running for it to work. However, since I’m usually watching TV with my remote anyway, this wasn’t a big issue for me.

Tips and Tricks
For anyone looking to replicate this setup, here are a few tips:

  • Code Customization: Make sure to update the Vera IP address and scene numbers in the code to match your setup.
  • IR Codes: If you’re using a different remote, you’ll need to find the corresponding IR codes. There are plenty of resources online that can help with this.
  • Power Management: Since everything is hardwired, I didn’t have to worry about Wi-Fi connectivity issues, which was a plus.

Conclusion
Overall, this project has been a huge success. It not only solved my problem with scene control but also opened up a whole new realm of possibilities for integrating different devices. The satisfaction of seeing everything work seamlessly was immense. If you’re into DIY projects and love tinkering with smart home setups, I highly recommend giving this a try!

Happy tinkering everyone! :rocket:
