Home automation is in demand. Whether it's as complicated as a fully automated home theater system with programmed lighting scenes or as simple as a single-room lighting control, homeowners are looking for ways to make their lives at home easier to manage and more convenient. "

According to a recent survey conducted by HAI, ... the most popular home automation applications cited were lighting control, energy management, and temperature controls," says Jay McLellan, president of Home Automation Inc.

Home automation technology is on the brink of change. For the past 25 years or so, systems have been based on X10 powerline carrier technology. Manufacturers say this works well for simple communication operations, but more sophisticated home electronics have placed greater demands on powerline carriers. Many manufacturers have begun looking for the next generation technology that will meet the future needs of more complex and integrated home automation.

"The industry recognizes that we can't continue to build our whole-home automation and lighting control based on a 25-year-old technology," says Mark Walters, director of engineering for Leviton.

Next-gen technology could take one of several possible shapes, but for the present, manufacturers stress the need for education among all building pros. "Sometimes that's a difficult proposition -- to take yourself out of money-making work for a day or two to attend a home automation training session," says Greg Giaque, media specialist for Lite-Touch. But Giaque points out that by learning about home automation systems of all types, can offer their clients something of while making some extra money themselves.

"Remodelers really need to educate themselves," says home automation installer Larry Dashiell, owner of HomeTech Systems Inc. in Santa Rosa, Calif. Dashiell is also an executive board member of the Custom Electronic Design and Installation Association CEDIA offers a wealth of information home automation industry, including lists of CEDIA-certified designer and members, on its Web site at www.cedia.net.

Dashiell recommends that remodelers get in touch with CEDIA-certified members in their area. "Interview these pros, find one you're comfortable with, and partner with that installer to educate yourself, and also to educate your clients, on the possibilities with these systems," Dashiell says.

The Consumer Electronics Association also offers a library of information on home theaters and home networking on its Web site at www.ce.org.
