The home automation system has been a work in progress since 2009. The most noticeable difference during the last years has been the introduction of the raspberry pi as the controller for the system. The raspberry pi is communicating with wireless relays through the 2.4GHz frequency through a USB-transmitter. The range of the system is increased by the addition of an external antenna on the transmitter. The system uses Debian Squeeze, MySQL, PHP, JQuery, Apache, amongst other things.
