Smart home technology was developed in 1975, when a company in Scotland developed X10. X10 allows compatible products to talk to each other over the already existing electrical wires of a home. All the appliances and devices are receivers, and the means of controlling the system, such as remote controls or keypads, are transmitters. If you want to turn off a lamp in another room, the transmitter will issue a message in numerical code that includes the following:
•An alert to the system that it's issuing a command,
•An identifying unit number for the device that should receive the command and
•A code that contains the actual command, such as "turn off."
All of this is designed to happen in less than a second, but X10 does have some limitations. Communicating over electrical lines is not always reliable because the lines get "noisy" from powering other devices. An X10 device could interpret electronic interference as a command and react, or it might not receive the command at all. While X10 devices are still around, other technologies have emerged to compete for your home networking dollar.
Instead of going through the power lines, some systems use radio waves to communicate, which is also how WiFi and cell phone signals operate. However, home automation networks don't need all the juice of a WiFi network because automation commands are short messages. The two most prominent radio networks in home automation are ZigBee and Z-Wave. Both of these technologies are mesh networks, meaning there's more than one way for the message to get to its destination.
Z-Wave uses a Source Routing Algorithm to determine the fastest route for messages. Each Z-Wave device is embedded with a code, and when the device is plugged into the system, the network controller recognizes the code, determines its location and adds it to the network. When a command comes through, the controller uses the algorithm to determine how the message should be sent. Because this routing can take up a lot of memory on a network, Z-Wave has developed a hierarchy between devices: Some controllers initiate messages, and some are "slaves," which means they can only carry and respond to messages.
ZigBee's name illustrates the mesh networking concept because messages from the transmitter zigzag like bees, looking for the best path to the receiver. While Z-Wave uses a proprietary technology for operating its system, ZigBee's platform is based on the standard set by the Institute for Electrical and Electronics Engineers (IEEE) for wireless personal networks. This means any company can build a ZigBee-compatible product without paying licensing fees for the technology behind it, which may eventually give ZigBee an advantage in the marketplace. Like Z-Wave, ZigBee has fully functional devices (or those that route the message) and reduced function devices (or those that don't).
Using a wireless network provides more flexibility for placing devices, but like electrical lines, they might have interference. Insteon offers a way for your home network to communicate over both electrical wires and radio waves, making it a dual mesh network. If the message isn't getting through on one platform, it will try the other. Instead of routing the message, an Insteon device will broadcast the message, and all devices pick up the message and broadcast it until the command is performed. The devices act like peers, as opposed to one serving as an instigator and another as a receptor. This means that the more Insteon devices that are installed on a network, the stronger the message will be.
On the next page, we'll take a look at the products you'll need to get your smart home running

Google announces Android@Home framework for home automation
Want more Android in your house? How about Android in your house. Google wants to think of "every appliance in your home" as a potential accessory for your phone. The opportunities are seemingly endless, the sort of thing we've seen in the Zigbee and Z-wave areas, but sadly this implementation doesn't actually seem to be using any of those standards. The team teased ideas like lights turning on and off based on calendar events, applications talking to washing machines, games automatically adjusting for mood lighting, and basically little green dudes taking care of all the menial duties in your house.
One amazing demo was a concept, Android-powered device hub called Tungsten. Using RFID embedded into CD cases the device was able to detect the CD and add it to your library. Another touch and it started automatically. Yeah, the use of CDs is a little quaint, but the potential is there for amazing things in the future. We're not sure exactly when these accessories will be launching, but the first are expected before the end of the year.

ZigBee vs. Z-Wave
When selecting a home control system, should you care if it’s compatible with Z-Wave or ZigBee?
It depends.
Both technologies enable two-way wireless control of various electronic devices including remote controls, dimmers and thermostats.
Both employ mesh networking, which means that the more devices that are on the network, the more powerful the network becomes.
ZigBee has a higher bandwidth, so it can accommodate richer information, such as metadata from your music library.
Z-Wave has the benefit of being a real “standard,” meaning Z-Wave products from one manufacturer are interoperable with those from other vendors (with a few exceptions).
ZigBee is trying to get there, but currently you cannot mix-and-max ZigBee products from multiple vendors.
Proponents from both camps claim they will own the market for “smart meters” and therefore will become the de facto standard. We’ll see.
Price-wise, the common perception is that Z-Wave is cheaper than ZigBee, but that really is not the case. It just so happens that most of the ZigBee implementers in the home-control space (AMX, Crestron, Colorado vNet, for example) serve higher-end markets.
Yet a ZigBee dimmer from Control4 can cost less than a Z-Wave dimmer from Leviton.
Bottom line is this: For do-it-yourselfers, Z-Wave is really the only option. You can’t just go out and buy ZigBee products.
For higher-performance systems, it doesn’t really matter. I wouldn’t use Z-Wave or ZigBee as a litmus test for choosing a home-control system. I’d go with the system that had the best features for my needs.
In any case, it’s tough to make a mistake on this one since a variety of adapter products exist.
Don’t Forget the Other Wireless Guys
If you’re in the market for retrofit solutions, also consider Insteon from SmartLabs. Insteon-compatible products are available for both wireless (RF) and powerline control (powerline products communicate over the home’s existing electrical wiring.) Insteon products are inexpensive and reviews on the technology are generally positive.
Universal Powerline Bus (UPB) from Powerline Control Systems is arguably the best technology for powerline-based automation gear.
And HomePlug, the organization that brought us high-speed powerline networking, has a new automation protocol called Command and Control. Like the Z-Wave and ZigBee advocates, the HomePlug Alliance believes its protocol will be selected by utilities for their smart-energy initiatives.

How Z-Wave Works ?
http://homeautomationgeek.com/signal-relay/z-wave/how-z-wave-works/
How does Z-Wave Work?
As technology evolves, it comes as no surprise that in the near future, we may be using remote controls to accomplish the simplest of tasks around the house. But in fact, the future could be already upon us…
Z-Wave’s advanced wireless system already provides for this increased convenience, interacting with its devices through a fixed electromagnetic field. This easy-to-use system is reliable, safe and secure, and best of all, you can install it without the need for dedicated wiring.
So precisely how does it work? Let’s say you’re in your bedroom, and you remember that you need to close the garage door. You instruct your Z-Wave system to do so; the command shoots from your controller, to the hallway fire alarm, and then bounces to the kitchen light switch, and finally to the garage door. This is the mesh network that Z-Wave utilizes, and it happens all in the blink of an eye.
Mesh network
The main difference between Z-Wave and the radio frequency (RF) component of Insteon is that in the latter, all of the nodes repeat signals each time a signal goes through the system. This is a true mesh network.
Z-Wave nodes do not go through this process; instead the intelligent, on-board software selects a route for the signal, and only devices on that route will repeat. The system is efficient, fast, and reliable – and it’s even self-healing.
Self-healing mesh network
One Z-Wave network can include up to 232 nodes. To avoid collisions, nodes make sure that there is no ongoing messaging traffic within the network before they begin transmitting data. This is one of the main advantages of a self-healing mesh network, like Z-Wave, where no central or master controller is needed.
In a mesh network topology, a command from node A to node C (considering it is outside range) can be communicated through node B. If that is not possible, another route will be automatically attempted in order to reach node C. This will repeat until the signal somehow reaches node C, no matter how roundabout.
To ensure that networks do not interfere with each other, nodes are dedicated to only one network and traffic is encrypted to secure it from outside traffic.
Most battery-operated devices, however, will not function as signal repeaters. Those that do so have to be permanently on the lookout for idling commands, thus shortening their battery lifetime.
The microchip
They say good things come in small packages, and that’s certainly true of Z-Wave. The entire Z-wave protocol is contained in a single microchip that is small enough to fit on your fingertip. Currently used in more than 200 products, the Z-Wave chip is a powerful, highly integrated, mixed-signal platform that enables your devices to be controlled and monitored wirelessly.
It contains six main blocks:
A radio frequency transceiver
A microprocessor
32kb flash memory, containing the protocol and application
Digital and analog system interfaces to connect to devices
An authentication 3DES system, which ensures confidentiality and security of your signals
A Triac dimming controller, which eliminates the need for separate dimmers, as everything is already on the chip
Two-way routing
Routing is an essential element in Z-Wave’s sophisticated wireless system. Through two-way RF routes, commands reach their destination by routing or passing signals from one node to another. This has the effect of extending the operational range to 45 meters (150 feet) indoors, and over 150 meters (500 feet) outdoors.
The robust and reliable wireless protocol provides full home and yard coverage through routing commands that work their way around sources of interference or radio dead spots, like walls, metals, fridges and other obstacles in your home.
Low bandwidth – high powered
Z-Wave uses Frequency-shift keying (FSK) modulation schemes, which is the technology used in cordless phones. It operates around 900 MHz, which is an ideal band for residential control applications.
This bandwidth is more than sufficient to send and receive the few bytes used in small messages, such as those required to switch devices on and off, dim lights and gather data from sensors. Because the amount of data communicated on these waves is small, reaction time is very fast, running at 9600 bits per second.
Network assignment
To use a network of Z-Wave devices, you need one primary controller, and one controllable device set up in its final position. Most users start with a portable controller, like the Intermatic HA07 and the Leviton RZCPG.
By entering a key sequence into the controller and pressing a button on the device, you can add the latter to the network. This standardized serial protocol process will have to be repeated until the controller is eventually paired with all the devices.
After initial installation, these devices keep their addresses within the network and remain connected full-time and operational unless in sleep mode. It is possible to bridge two or more networks, though this is not usually necessary in a small and controlled residential environment.
Z-Wave manufacturers, Zensys, have literally redefined the notion of home automation through their well-knit wireless mesh network, but the system does have its drawbacks. Visit our pros and cons (link: 23_Z-Wave pros and cons) page to learn more about the system.
