MediaRC is a remote control program intended for controlling various media devices found in a home theater or with a PVR like MythTV. It is an extendable program for which new drivers can easily be added. MediaRC currently can control IR devices through LIRC, the sound levels through ALSA, and serial devices like a TV.
Minerva is a complete, easy to use home automation suite. It allows you to switch your on lights from anywhere using a mobile phone or PC, email your video, check CCTV footage, control your central heating, and much more. It relies on command line and can therefore be run from virtually any platform (smart phone, PDA, laptop, or remote PC) with identical functionality. The architecture consists of three parts: input, output, and process. Each is completely distinct, meaning you can control any of the house processes from any supported input conduit such as a Web browser, remote control, or SMS. Reports or notifications can be sent to any of the available output conduits.
MoCo is a system that monitors and controls SCADA points, such as temperature, HVAC, power, lighting, sprinkler systems, and more. It has industrial capabilities, but is scalable from very small home systems to enterprise, world-wide ones. It works with inexpensive I/O bridges (including X10, Insteon, and 1-wire) from a number of manufacturers. It has sophisticated history logging and diverse control capabilities, as well as a 117-page implementation manual.
Mobi is general purpose Bluetooth remote control software which exploits the SonyEricsson accessory interface. It searches for phones and, if found, loads a configurable menu into the phone which allows you to perform custom actions on the connected computer, such as requesting status information or playing music.
OWFS (One Wire Filesystem) allows easy control of the 1-Wire bus under Linux. The bus can either be viewed in a Web browser (OWHTTPD) or as files (OWFS). This makes manipulating the 1-wire devices easy with shell scripts, Perl, C, and other programming languages. 1-Wire devices are intriguing chips made by Dallas Semi. They are cheap, uniquely numbered, and take minimal wiring to connect (a data/power line and ground are all that's required. Chip functions include memory, switches, counters, and sensors of temperature and voltage.
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.
