1. heyu - 2 way x10 communications for the CM11A heyu' is similar to the package 'x10', differing mainly in the controller supported (this package supports CM11A, 'x10' supports the CP290) X-10 modules are devices that plug into an electrical outlet and allow you to remotely control the power to a lamp or an appliance that is plugged into them. There are also X-10 modules that install in place of wall switches to control lights, fans, and many other appliances. This package supports the CM11A Interface (from Radio Shack), which supports two-way communication. This allows for devices such as motion detectors to trigger scripts on your system, turning lights on, updating web pages, or send you e-mail.
