Z Wave Home Automation

ha_graphicsZ wave protocol is a protocol designed to bring about home automation by controlling applications via a remote control in residential as well as commercial environments. The wireless protocol works through low power RF radios which are either in-built or retro fitted into systems and devices such as entertainment systems, access controls, lighting and other household appliances.

What is Z wave technology?

Z Wave technology operates on a number of sub-GHz frequencies across the world. Some common frequencies include 908.42 MHz in Canada and US and 919.82 MHz in Hong Kong. This technology uses two way RF mesh networking and targets energy management and home control. The technology offers a low latency cost effective and low power solution like other technologies such as Bluetooth and WiFi Direct.

Its mesh network makes use of source routing and has the capacity to support up to 232 nodes on one network. To enhance the reach, you can combine two networks. Z Wave can also co-exist with other common home networks such as WiFi and Bluetooth without causing any interference in each other’s operation.

Origin and evolution:

z-wave-logoThe origin of Z wave can be traced back to the year 1999 when a company called Zensys founded it with an aim to develop wireless solutions for home automation and remote controlled appliance industry. Besides the Z wave wireless mesh network, the company’s transceiver chips have also been integrated into several household appliances.

It was in 2005 that Zensys shaped an organization called the Z Wave Alliance. This was done with an aim to administer and promote the Z Wave standard in the markets. This alliance has been regarded as the sole reason behind the success of Z Wave protocol in the consumer markets. Once the company and the alliance listed and implemented the integration of all definitions and specifications in Z Wave products, it became possible to inter-operate Z Wave devices manufactured by different manufacturers. As of date, the Z wave protocol has been integrated with more than 1000 consumer electronic products.

 

What can you do with Z Wave?

Z Wave basically allows devices and objects enabled with sensors to communicate and respond to each other at a price which everybody can afford. You may argue that such a feat can be accomplished by using other protocols such as 802.11 WiFi and Zigbee also. However, the fact remains that since Z Wave operates in 900 MHz band instead of 2.4 GHz like 802.11 WiFi, it provides superior performance due to reduced interference. Also the fact that it has larger wavelength and can thus penetrate walls and objects more easily than other protocols cannot be ignored.

Let us now see what you can do with this 900 MHz Z Wave power at your disposal. If this was to be answered in one word, it would be “Plenty”. With Z Wave technology working for you, you can control fans, lights, shades, irrigation systems, security systems, drapes, door locks, electrical outlets and much more remotely. You can control your entire home from a wireless key while lying on the couch, through a wall mounted keypad in your bedroom or through a smart phone or tablet connected to the internet from anywhere across the globe.

However, Z Wave scores much over these systems because it accomplishes these feats at barely a fraction of the price. With an ever increasing army of interface modules compatible with Z Wave, tons and tons of additional control systems are being offered to the users.

Benefits of Meshing Around:

In a conventional RF network, the resources of the network get sucked in by every extra device that is added to the network. Extra devices can either cause the system to slow down or produce such levels of interference that the system crashes.

It shall surprise you to know that with Z Wave, the case is exactly opposite. All Z Wave enabled devices create a mesh between them which gets stronger with every extra device that you add to it. This is because when new members are added to the group, the new member creates the most favourable pathway to send and receive data and every device acts as a repeater for the other. In the case of a single device failure, the mesh undertakes self healing by routing the signals through a new transmission pathway. A wise analogy can be made by comparing Z Wave to a colony of active ants where every obstruction in the way is overcome by pressing on and finding a new way to the colony.

What do you need to have?

To make use of Z Wave, you must have at least two Z Wave enabled devices such as a remote control and a dimmer. You can begin your automation journey by procuring these two devices at cheap prices from a number of online stores.

Since a lot of users want to operate the system through the internet, they require a Z Wave gateway also called a Central Control Device. This device is responsible for connecting to the modem/router as well as acting as the Z Wave hub controller and portal to the “world wide web”.

Another benefit of the Z Wave is that you only need batteries to send control signals. Since Z Wave transmits at a much lower power, batteries generally last up to 3 to 5 years. Z Wave makes a perfect solution for homes that want to embark on an automation journey. You can subsequently add new technologically advanced devices to the house and upgrade the system to fulfil all your automation whims.

It shall not be an overstatement to say that Z Wave has completely transformed the idea of home automation. It becomes important to procure your Z Wave enabled devices from reputed online stores such as Fibarozwaveshop.com to ensure that you get genuine products as well as seamless after sale service.

If you are also tired of living in a dumb house where appliances respond only when you reach them and twist their ears, it’s time to become smart and ride the wave: The Z Wave.
