Integrating HTD with OpenHAB: A Smooth Experience

As a homeowner who loves experimenting with smart home tech, I’ve always been on the lookout for ways to integrate my entertainment system seamlessly with my smart home setup. Recently, I decided to dive into integrating my Home Theater Direct (HTD) whole-house audio system with OpenHAB, and I must say, the journey was both challenging and rewarding. Here’s how I made it work!

First off, I wanted to control my HTD system using Google Home, which meant creating a bridge between HTD and OpenHAB. The key was setting up a TCP connection. I installed the TCP binding in OpenHAB and made sure to configure the charset in tcp.cfg to Latin1. This was crucial for ensuring smooth communication between the systems.

Next, I created some string and switch items in my items file to represent the different zones and sources in my HTD system. For example, I set up switches for ‘kitchen_audio_chromecast_audio’ and ‘kitchen_audio_home_automation’, which allowed me to assign different audio sources to specific zones. A dimmer item was added for volume control, enabling me to adjust the kitchen zone’s volume via voice commands.

The real magic happened with the Jython rules. I wrote a script that listens for state changes on these items and sends the appropriate commands to the HTD gateway. This meant I could say, ‘Hey Google, switch on kitchen music,’ and the system would automatically assign the music source to the kitchen zone. Similarly, adjusting the volume was as simple as saying, ‘Set kitchen volume to 50%.’

One thing I learned was the importance of having a ‘silent’ source mapped to a zone. This ensures that when I turn off a source, the system doesn’t leave the zone in an awkward state. It’s all about those little details that make the integration feel seamless!

While the setup required some trial and error, especially with getting the TCP connection right, the end result was worth it. Now, controlling my home theater system feels just as intuitive as adjusting my smart lights. If you’re looking to integrate your HTD system with OpenHAB, I’d highly recommend giving this method a try. It’s a fantastic way to bring your entertainment system into the smart home fold!

I’d love to hear if anyone else has tackled a similar project or has tips for improving this setup. Happy tinkering!
