A couple of days ago, I discovered Perceptive Automation's excellent Indigo home automation software for the Mac. I installed the evaluation version on my Mac Mini server and disappointingly discovered there was no built-in support for the Lutron RadioRA (what Lutron now calls "RadioRA Classic") lighting system that I have in my home.
I briefly looked at the various Insteon products that Indigo supports, but it appears that a fair number of people have experienced failure of its hardware components. I have had absolutely no problems with my RadioRA system in the 4 years its been installed so abandoning it was not an option.
Fortunately, Indigo introduced a server plugin API in its latest version (version 5 as of this writing). This allows a developer to use a combination of XML and Python to integrate unsupported hardware. Given that a RadioRA system can be controlled via RS-232 using a Lutron RA-RS232 controller, it seemed like a straightforward task.
I quickly got to work using some of the example plugins provided with the Indigo SDK to create a RadioRA plugin. I had no prior experience writing Python code but it all came together fairly quickly. Since it only took a day to create, I decided to make it open source so others could benefit from and hopefully contribute to it.
This plugin has the following requirements:
