Case Study Interview

"The company has an astounding 100 million US installed base of home automation systems. This includes both modules, such as plug-in lamp or appliance modules that turn off the lights, and controllers, which turn something on via remote control, timer, telephone, computer, etc. Dave Rye estimates that about 5 million homes have X-10 modules."

CHAC & Homation

"HomAtion cleverly allows anything to trigger anything else. You can have events trigger scenes, scenes create events, events cause events, etc. You can create variables to pass data from one scene to another. You create a scene the same way you add a device, except you attach events to it."

International HA

"Even though progress on international standards is relatively slow, participation is important for the exchange of ideas among home automation developers world-wide. The specification of application models may promote product interoperability. This may be more worthwhile than the current focus on protocols, which is encouraging protocol competition."

Marantz RC2000 MKII

http://www.marantzamerica.com/rc-2000.htm "Beyond the obvious multitude of buttons allowing control of every device you own, there are 4 macro buttons situated beside the LCD display. These can be programmed with up to 20 steps each. For example, you can program one button to turn on the TV, turn on the VCR, Change to channel 6, Set the amp to surround sound and take out the dog."

Primer on CEBus's Common Application Language (CAL)

"Now that you have this home network defined, take a moment to realize that your iron, security system, garage-door opener, front porch light, ceiling fan, television and master bedroom alarm clock radio can now freely pass information back and forth amongst themselves. Part of our challenge is to identify what (if anything) one of these devices might want to 'say' to the others and why the others would care to 'listen'."

Sweet Automated Dreams

"Another remote control in the bedroom is built into a custom console mounted on the under side of the headboard. The entire console is illuminated with glowing LEDs for use in the dark. In addition to the X-10 control, there is a clock, security control panel, and an indoor/outdoor thermometer."

Too Many Remotes

"When you are entertaining or just watching a movie by yourself on a Saturday night, you don't want to be fiddling around will all of these remotes. If you do not do something about this, your couch will have a wonderful display of large, and usually complex remotes for which you need an engineering degree from MIT to use. Don't worry, there are some solutions. "

Troubleshooting Three-Way and Four-Way Switch Circuits

(DVD) Digital Versatile Disc

"In the future, DVD will offer the viewer multiple camera shots so you can view a scene from different angles and levels. DVD's will be recordable, rewritable, and reusable ... a big plus for the computer industry"

Cardio

"I haven't had much luck convincing my better half that home automation systems are easy to use but when I asked her to look at the touchscreen operation of the Cardio, she was enthusiastic and understood immediately what was required to operate the system. That fact alone is enough to convince many that the system is worth the effort."

HOME AUTOMATION OUTSIDE NORTH AMERICA

"A major announcement affecting the building and home automation markets in Europe was made in June 1997. The Executive Director of EHSA announced that the EHS, EIB, and BatiBUS communications protocols would be merged into one protocol."

How it all started

"The idea of using the existing AC wiring to transmit signals to control lights and appliances was conceived (like so many Pico/X-10 ideas) over several drinks in a bar one night. If we had known then how long it would take us to get to where we are now, we would probably have moved on to project X-11 :-)"

Interoperable Control Systems

"The LonPoint System includes a family of interface modules that provide various combinations of digital or analog inputs and outputs along with numerous software function blocks, allowing seamless connectivity to legacy field devices and to LonMark devices."

Powerline Communication Security Issues

"When installing an automation or control system in your home that utilizes the powerline for communication, you should begin by educating yourself on what potential security risks there are and use sound judgment in determining how realistic the security breech scenarios are."
