There are many automation systems in the marked, but only one exclusively based on Wi-Fi (IEEE 802.11) and oriented for a home environment, it is coming from the hand of CISIUM.

In this article we explain and provide the material for an open source and open hardware Wi-Fi Home automation system; this is our contribution for the community.

The principles of our proposal are:

• Easy to use, targeted for people without technical background.
• Without the necessity of any technician to install the automation system.
• Based on a standard wireless communication: Wi-Fi (IEEE 802.11).
• Taking advantage of already exiting standard IT infrastructures: router, access points, etc.
• With smart phone / tables support and interaction.
• Capable to integrated 3rd party Wi-Fi devices.
• Affordable.

The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It's a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games.
