Zigbee vs. Z-Wave Review: What’s the Best Option for You?

Written by | Updated December 14, 2018

In the early days of home automation, systems were hardwired and required technicians for installation and updates. As a response to customer demand for more control, home automation companies developed wireless technologies that communicate via Wi-Fi and Bluetooth instead. Z-Wave and Zigbee are two examples of this technology, and they both allow customers to remotely control multiple home automation devices.

If you’re considering automating your home, you first need to decide what language your hub — the “brain” that controls your devices — will speak. Z-Wave and Zigbee are two of the most popular languages, or wireless technologies, available. While they offer similar products, they differ in their benefits, drawbacks, and consumer bases.


Zigbee is open technology that has become the global wireless standard language of smart device communication. While Zigbee was originally developed for commercial use, it now serves as the sensing and control standard for use in residential, commercial, and industrial areas.

How It Works

Zigbee connects your devices using a “mesh” system where information from one device jumps to others until it reaches the hub. This allows your network of home automation devices to grow in number and signal reach without requiring high-power transmitters.


Zigbee’s open technology is the language for thousands of smart home devices. Many different companies create devices that communicate with Zigbee’s technology, allowing you to seamlessly integrate products from a variety of manufacturers.


Zigbee uses AES-128 encryption — the same level of protection major banks use — and network keys to keep your devices secure. However, because devices using Zigbee technology are manufactured by many different companies, standards vary. Zigbee device makers recently received criticism for their minimal security measures when researchers demonstrated that even a door lock was easily vulnerable to potential hackers.


The Zigbee Alliance consists of nearly 400 member organizations that use, develop, and improve Zigbee’s open-standard wireless connection. Customers can easily mix and match home automation devices from different companies and add new devices as their needs change.

Biggest Pro

Zigbee prides itself on requiring so little power that devices can last up to seven years on one set of batteries. They also have a Green Power option that allows customers to select devices that do not require batteries at all.

Biggest Drawback

Zigbee was developed for use in the utility and retail industries. While it is also popular for home use, it requires that consumers have some technical knowledge for setup and maintenance.

Who It Serves Best

Zigbee is perfect for the DIYer or technology expert who wants a system they can customize with their preferences and install themselves. You can “control your world” with the scalable and compatible Zigbee network.

Z-Wave is one of the original wireless network technologies for home automation. Its proprietary technology was developed specifically for customers to remotely control and monitor their home automation devices. Z-Wave continues to set the standard for automated lighting, heating, security, appliances, and other smart devices.

How It Works

The Z-Wave hub serves as your home network’s controller, allowing up to 232 devices to wirelessly communicate with each other. The more connected devices in your system, the further your signal can reach. Similar to Zigbee’s mesh system, Z-Wave signals “hop” from one device to another so two devices located outside signal range can communicate via devices in between.


The Z-Wave Alliance consists of 375 companies and 1,500 products that are all interoperable with each other. Nine out of ten leading security and communication companies in the U.S. use Z-Wave in their smart home solutions. Z-Wave technology has 325 manufacturers, which means that there are many options for devices that will communicate with each other.


Every Z-Wave network, and the devices within each network, are assigned unique IDs that communicate with your hub. This makes it so another hub can never control your hub’s connected devices. Devices like door locks and alarms require even more security, so Z-Wave also uses AES-128 encryption.


You can update your smart home devices — including Amazon Echo or Apple Watch — as often as you would normally. As long as the devices continue to speak Z-Wave’s language, Z-Wave will be able to act as your smart home’s central hub.

Biggest Pro

Z-Wave is user friendly and provides a simple system that customers can set up themselves. If you prefer, you can also hire a professional to install the system in your home. Once you purchase your Z-Wave hub, you only need to decide which devices you want to connect.

Biggest Drawback

Depending on how many devices you choose, your Z-Wave system may be expensive. Z-Wave products typically range from $40 to $100 each, which can add up quickly if you want to connect many devices.

Who It Serves Best

Z-Wave is ideal for someone with a basic understanding of technology who wants to keep their home automation secure, efficient, simple to use, and easy to maintain. Z-Wave works with the most popular brands and smart home devices, so customers shouldn’t experience limitations.

Although Zigbee and Z-Wave feature similarities with their mesh networks and wide range of devices, they each offer unique advantages for different customers. Compare their features to determine which wireless technology best fits your home automation needs. Get started with Z-Wave by shopping its range of controllers, or launch your Zigbee home automation system by shopping a complete list of its certified products.

    Thank you Sarah for this wonderful article. I just bought an Amazon Echo and had begun looking at the New Echo Plus with the builtin hub and did a quick duckduckgo search for Zigbee vs Z-Wave. This was one of the top searches. You did a wonderful job at getting straight to the point on both topics. I am kind of torn between the both. I love to make small electronics with Arduino and Raspberry Pi so it sounds like Zigbee would be my best option. However, I do love how secure Z-Wave is. This will be a hard decision to make on the route I should go to begin my home automation.

      Keith, thanks for checking out our article. We’d love to hear what you decide to go with and why. Keep us updated!

        So it seems that amazon has decided to go with Zigbee with their new Echo Plus. This could be due to the worldwide use of the 2.4Ghz band. I really want to use Z-Waze in conjunction with Alexa. Z-Wave has better security and more devices (at this current time). So what I have done is bought the 2nd Gen Echo and will integrate it with Samsung SmartThings hub. This hub allows me to use Zigbee AND Z-Wave products. The hub will also allow me to write routines for my devices and Alexa “should” recognize them as scenes. For example I want my porch lights to turn on/off at sunrise/sunset. I have seen people post about doing this using routines on the hub. This will definitely be a work in progress.

    Sarah great article and I am looking forward to more and easily accessible information on home automation. Meanwhile, you may want to mention that a Zigbee network can manage 65,000 devices compared to a good 200 only on a Z-wave network, which is a limitation of Z-wave.
    And, in a Zigbee network, a command can jump an infinite number of “hops” as opposed to Z-wave that allows only for four hops. This can be a serious limitation of Z-Wave in a larger residential project.
    As opposed to what your blog suggests, I don’t think that Zigbee comes with any more security concerns than Z-Wave. Sure, the ecosystem is less controlled, but afterall you can choose yourself the manufacturers that care for security. And at the security protocol level, Zigbee and Z-wave are identical and have both implemented AES128 encryption.
    I think it is exaggerated to say that Zigbee devices are harder to install and configure than Z-wave “because they used to be for professional markets only”. Take, for instance, Philips Hue: a zigbee setup that anyone installs and configures in just minutes.
    Finally, your text suggests that the Apple Watch is a Z-Wave device, but that is incorrect. It uses your WiFi connection to to connect with the Z-Wave or Zigbee hub. Just like your smartphone.
