Do I Need One?

The system processor is the black box that helps coordinate and control all of the sub-systems in a smart home. These might include: lighting control, heating/AC, security and surveillance, home theater, internet communication, multi-room music and more—including apps for special-needs household members.

Most processors are essentially proprietary mini-computers which communicate over wireless and/or wired networks to the sub-systems in the home, through specialized data ports, using specialized control languages.

Some processor brands can communicate only with peripherals (keypads, thermostats, and lighting devices, for example) made by the same manufacturer only. Others are adaptable to a virtually unlimited range of brands and component types.

An essential function of the system processor is monitoring and controlling systems via dedicated in-wall keypads, wireless handheld remotes, or even smartphone apps. This allows the user to manage multiple home integration systems from multiple locations—a function which is central to effortless smart home operation. See Smart Home Control.

Technical aspects of the system processor and peripherals are typically beyond the interest of most consumers. But the practical aspects—how well a given system will meet your specific needs—are of critical importance, and deserve close attention. Here are some questions to think about and discuss with a smart home expert before deciding on a system:

  • What are the specific limitations of the system I’m considering, and how easy—and cost-effective—is expansion of that system?
  • Will I want to add new systems later (such as security cameras, or shade controls), and how easily can the system processor in question accommodate them?
  • What are the programming costs for the system I want? Is the programming for the system “drag and drop” style, or is every project programmed from scratch, requiring a unique source code. If the latter, who owns the completed source code, and do I get a copy of the code?

Choosing the right system processor—and expert—to integrate your home is an important decision, perhaps as important as deciding which sub-systems you want. For more information on smart home integration, see My Needs, and Tailor the Technology to Your Lifestyle.
