As smart homes get smarter, innovators continue to look for ways to improve connectivity. No one wants to buy a device that doesn't work because of router distance. More innovators prefer to use a mesh network where each device transmits data to the next device in the system before accessing the hub and vice versa.


Z-Wave is a wireless protocol used for smart home automation systems and to transferring data between different devices. It uses low energy radio waves to transmit information. It can be used to control everything from security systems, opening and closing doors to thermostats. You can use a Z-Wave gateway, a Z-Wave controller such as a smartphone or a dongle.




The Danish company Zensys developed Z-Wave in 2001 as a system that only controls lighting. Z-Wave Plus was launched in 2013 and offers longer range, more memory and improved battery life. The Z-Wave Alliance was founded in 2005 to promote Z-Wave technology. Z-Wave networks can support more than 200 devices more than 30 meters away. Obstacles like walls shorten the distance. Z-Wave devices operate at a frequency of 908.42 MHz, which is far from the frequency used by your home Wi-Fi network.


What Z-Wave devices do you have? All smart devices supported by Z-wave, regardless of brand, must be compatible with each other and must be certified by the Z-Wave Alliance. These smart devices include locks, switches, thermostats and more.


Why are Z-Wave devices important for home automation?


Z-Wave is important for home automation for several reasons:


1.    Easy to install


Many people learn how to install electronics and usually pay a technician to do the installation. Z-Wave SmartStart is a feature that simplifies device setup. SmartStart means all devices are pre-configured before they are sent to the store. Installing a new device is as simple as turning it on. The network gateway automatically recognizes and connects to the device.


Scan your device's QR code to see if you've added a new device to the gateway, recognize your device, and connect to it. If not, instructions are provided for connecting the device.



2. Interplay


By design, Z-wave devices are compatible regardless of brand, type, version or manufacturer. The list of Z-wave certified products has grown from 1,700 in 2017 to 2,600 in 2019. This interoperability eliminates compatibility issues when using multiple devices. Once a Z-Wave device is certified, it works with other Z-Wave devices.




3. Low energy consumption


Some smart home devices use power and others use batteries. These devices are mainly sensors that do not work continuously throughout the day, such as window sensors. The main purpose of a smart device is to provide convenience, which is often inconvenient due to a dead battery. Low energy consumption is important for this.


The future role of the Z-Wave Alliance


According to Silicon Labs, the Z-Wave Alliance is the organization responsible for the Z-Wave specification standards. The Alliance is responsible for administering the Z-wave certification program to ensure compatibility of Z-wave devices.


By mid-2020, the Z-wave specification will also include ITU. The G9959 PHY/MAC radio specification is required to build a Z-Wave chip, host device communication protocol, network and application layers. This allows other silicon manufacturers to create Z-Wave chips and bypass Silicon Labs as the sole source of Z-Wave components for end-product manufacturers.


The benefits of using Z-Wave products


Benefits of using Z-Wave products include:


Saving energy


Z-Wave technology helps save electricity by, for example, turning appliances and lights on and off at set times. Z-wave technology helps you automate your home, easily access it remotely, expand your connections and save energy. Availability and compatibility


There are currently over 1,000 compatible Z-Wave products. All Z-Wave products are easy to use and compatible with each other. wireless technology


Z-wave makes common household appliances and products like thermostats, locks and lights smart. When connected via Z-wave, these products can communicate wirelessly and be controlled from a computer, tablet or mobile phone.


Buying guide

Here are some things to consider before buying a Z-wave device:

Z-Wave Alliance certified


Z-Wave certification allows you to verify that your device is compatible with other Z-Wave devices from different brands. It is a compatibility and interoperability feature and smart devices from different manufacturers can communicate easily. the country of the device




Check the availability of smart device packages.

Smart device bundles and bundles containing these smart devices are sometimes available. Instead of buying the tools individually, you can buy them in sets or bundles. In the long run, it's cheaper.


Plan what to buy


List everything you want to automate. Make a list of things you need to replace and buy. Includes the cost of replacing and removing current manual devices.




If you want to automate your home, you need to think carefully about what to replace and consider the cost. The Z-Wave Alliance has made it particularly easy with many compatible devices on the market. If a device uses Z-wave, it can communicate with other devices using the same protocol.
