The characteristics of home automation are essentially three. Its architecture, broadcast and communication protocols. Not to be a fairly long post, this topic will be divided into two parts. In this post will be addressed first the Architecture and Communication Protocols.
Architecture
- Centralized Architecture
It has a central element, through which pass all the information. This type of architecture is usually more economical because it removes the ability of processing from the various devices, and centralizes all in one device. Type of architecture typical of proprietary systems. (cardio, mordomus, empower, etc.).
- Decentralized Architecture
Don`t have any central element. This form is more flexible and fault tolerant because the failure of an element does not compromise the functioning of all others. This type of architecture is used by leading home automation protocols, including the X10, Z-Wave, ZigBee and KNX.

Communication Protocols
Communication between two devices needs not only a mean of communication, it is also necessary that both use the same communication protocol. The protocol indicates the message format and language common to all devices so that they understand each other.
There are several different protocols may be:
- Standard Protocols
Are characterized by being open to any technology company, ensuring the future of technology and the existence of a huge variety of products from different manufacturers, which communicate and interact.
- Protocols owners
They are developed by a single company and only that company, or other licensed by, can manufacture products that can communicate with each other. The investment in this solution involves a huge risk because if the company decides to stop betting on this technology, the customer is no guaranteed support and is not possible to expand the system.
