gnhast is a collection of daemons that work together to build an event-based home automation system. Any event (such as a light being turned on) can be handled by an external script or program. These programs can be written in any language, and the central daemon handles all the intercommunication. It is designed to be easily extensible for new device types and protocols.
PAUS is a system for controlling stuff with simple event-based Perl scripts. It can be used for controlling your house, creating an alert system, or making a remote controlled mp3 player. It is a flexible project that "merges" other I/O projects together, such as lirc (remote control), lcdproc (LCD output), mpg123 (mp3 player), and various I/O boards (such as the K8000). It's modular, extensible, multi-threaded, and has networking support.
Device::ParallelPort is a Perl API that allows low level access to the parallel port of most computers. It does this by using a number of drivers, which can be customized and added to, including Linux (direct and parport), Win32, Script, Dummy, and more. It also contains a number of direct access devices including an example printer and a relay controller card.
jHomenet is a home automation application. jHomenet uses both X-10 and Dallas Semiconductor 1-Wire network sensors and devices to collect sensor data and control devices. jHomenet can be programmed to respond to events, including particular sensor data values or time-of-day events.
domus.Link is a Web-based frontend for Heyu. Its design focuses on separating configuration from actual controls, thus giving the user a simple and user-friendly GUI. The primary concern is that anyone with little or no knowledge of home automation systems can easily manage and administer the system.
Cerberus-Prox is backend software for an inexpensive, easy-to-build hardware system that implements a functional door access control system. It supports HID clock-and-data prox card readers. A MySQL database (or theoretically any JDBC) is used for data storage. RXTX is used for serial port communication.
