Maybe you have ever read the term Z-wave but, do you know what it is or what it consists of? We explain everything you need to know about this new wireless network.

While we still do not live in smart homes like those in science fiction movies, we have more and more appliances, sensors and devices connected to our home to automate and control endless tasks.

The Internet of Things already has some route: in 2015 there were already 5,000 billion IoT devices, according to data from the Gartner consultancy. To cover this growing community of devices, without overloading traditional wireless networks, it was necessary to find another connection channel with features designed exclusively for your needs.

Following this new need arose Z-wave, the international standard for the wireless interconnection of home control systems. It is a wireless network similar to Wi-Fi and Bluetooth, but whose specifications have made it the perfect choice for the devices that form the so-called smart homes or the IoT universe.

From lamps to thermostats, speakers, coffee makers, alarms and blinds, today we can find in the market a wide variety of connected products or home automation, using Z-wave technology, designed by the Danish company Zen-Systems.

Why has this network become the communication protocol that manufacturers have been waiting for for years? What characteristics does it have?

Like Wi-Fi, this technology is wireless, reaches a similar distance from one point to another and is based on advanced security techniques to ensure that no cybercriminal can sneak in during the transmission of information. In addition, both technologies allow to create a mesh or mesh network communicating among themselves a multitude of devices, something that Bluetooth technology can not do.

But here are the main differences: while Wi-Fi allows you to send and receive large amounts of data so that we can watch movies or play video games online, devices that use Z-wave send much smaller codes, such as “turn on the light “,” lowers the temperature “or” closes the door “. What does this mean? It allows operating at lower frequencies and with less power, avoiding the most common frequencies such as 2.4 or 5 Ghz and which are now more saturated.

The Z-wave network has two sets of nodes: the controllers and the slave devices. The main controller creates the entire network of our hogat. Connecting it to the Internet we can direct our home even if we are miles away.

For example, if you want to raise the blinds or connect the heating but you are away from home, from your mobile you can tell the controller these actions and he will be responsible for activating the necessary sensors in the home automation network.

It is true that there are many other technologies that also serve this purpose, but Z-wave is currently one of the most robust and also has the support of the Z-wave Alliance, a group of more than 700 companies, manufacturers of IoT technology who are responsible for certifying all devices compatible with Z-wave market.
