Let’s get started!
What Is Z-Wave?
To make your life easier and your home smarter, Zensys brought to life Z-Wave in 1999. Since then, it has received tremendous popularity and has surpassed its competitor, Zigbee.
Now it’s the technology that allows devices at your home to communicate with each other. This one employs radio wavelengths to connect all the devices.
How Does Z Wave Work?
Z-Wave uses a radio wavelength of 800-900MHz to connect the smart devices at your home. Together they all contribute to making a mesh network, which allows you to avoid interference.
Well, simply put, Z-Wave is something similar to Bluetooth but has a bigger range. And it is more energy-efficient than Wi-Fi. And as Z-Wave is a mesh technology allowing a variety of devices to connect and communicate wirelessly with each other, therefore, it has a strong network.
What Is Z-Wave Plus?
Well, everything has become more efficient due to improvements in technology, television, laptops, phones all have become thinner, smarter, and simpler to use.
Similarly, since its conception in 1999, Z-Wave has gone through several transformations, and its latest development is known as Z-Wave Plus (Series 500 Chipset).
It offers an enhanced battery life (by 50%), increased range by 67% and bandwidth by 250%, better ability to self-heal, updated Over the Air (OTA), and much more.

What are the Benefits and Drawbacks of Z-Wave?
The formulation of Z-Wave technology provides its users with a plethora of advantages.
Any smart devices can connect with Z-Wave and immediately start communicating with each other, so it easily adapts with each and every smart device.
Z-Wave is a wireless technology, and so there is no need for you to actually attach one device with another with a bunch of additional wires. You can do the installation by yourself as there is no need for any construction. All the devices need for communication amongst themselves is to be within 50-100 feet of each other.
- Installation Is Easy as Pie
You do not need to have any building or technological knowledge to be able to install Z-Wave devices to make your home smarter. It also allows you to install devices at your own pace.
For example, you do not need to install lighting, heat, or motion sensors all at once; you can install them whenever you want without worrying about paying contractors to install it for you.
Z-Wave is not only smart for your home; it is smart technology in itself because of its interoperability. It allows you the freedom to choose from a variety of products from hundreds out there, made by different manufacturers, and yet Z-Wave allows them to work altogether.
Z-Wave devices such as a thermostat, heating control, motion and temperature sensors are all battery operated, but saving energy is an utmost concern. Hence, devices have been designed with batteries to last one year or more in order to optimize the energy efficiency of devices.
Furthermore, ZWave devices emit significantly lower electronic smog (discharge of wireless signal) that is harmful to human health. For example, devices such as light dimmers, sensors, socket modules, etc. emit almost 4000 times less electronic smog than a cell phone.
- Signal Range
Devices typically operate from 868.42-908.42MHz. So, there is no fear that it would interfere with your other wireless technologies such as WiFi, microwave, phones, etc.
You must be worried about security as technology can be used to disarm other technology. With this in mind, Z-Wave employs AES-128 to provide a secure network to its users.

As technology has improved significantly since the appearance of Z-Wave in 2000, the range of these products has increased, as well. The usual range of signals of these thermostats is 100 meters outside and 50 meters inside the home.
And what’s more interesting is that you can increase the range as well as a network of Z-Wave simply by adding more of their products because this is a mesh technology (all Z-Wave devices can communicate and send information amongst themselves).
Despite its many advantages, Z-Wave has some disadvantages, as well.
- Limited Transmission of Signal
All your devices connected to Z-Wave must be situated within 300sqft. If devices are beyond that, devices may not be able to receive commands from the main hub due to loss of signal. Hence, you will need to install more devices, and this will increase your costs exponentially.
- Technological Know-How
Although you do not need to know how to install Z-Wave devices as it is quite simple to install. However, you do need to know to keep the devices connected to Z-Wave safe from hackers as it works on radio frequency, and its wireless nature makes it accessible to everyone.
- Limited Speed of Communication
The speed of communication goes up to 100kbps, which is quite less than Zigbee, and also due to a slower speed, devices communicate based on small data, which means greater monitoring and controlling is necessary.
- Tree Topology
If you are not familiar with this concept, you need to become acquainted with it as Z-Wave only supports tree topology structure.
Alternatives of Z-Wave Protocol
There are several alternatives to Z-Wave out there. If you are not satisfied with Z-Wave, there is ZigBee, INSTEON, Universal Powerline Bus (UPB), Wi-Fi, Bluetooth to choose from.
It is similar to Z-Wave in that they are both wireless and use mesh technology. And it has more devices that are compatible, around 2,500 devices from 400 members in ZigBee Alliance.
ZigBee has a slight edge as more popular and renowned smart home brands are associated with ZigBee. ZigBee uses very little power, and the ZigBee products are powered by a battery that lasts for years as they consume very little power.
If you have decided to go for all the best smart home brands and want a faster connection, then ZigBee, maybe your best choice.
While ZigBee and Z-Wave both are wireless and boast mesh technology, INSTEON differentiated itself from the pack by having dual mesh technology. So, not only the device can communicate using INSTEON’s unique radio frequency, but also the electrical wiring.
In case the radio frequency ever gets interrupted, devices will automatically transmit data through the electrical wiring. INSTEON devices are forwards and backward compatible, and so even old INSTEON devices can work perfectly fine once it is connected to the central hub.
Every time an INSTEON product is installed to its central hub, each and every device transforms into a repeater and thus enhances the signal.
INSTEON also makes its own products, unlike Z-Wave or ZigBee, and offers around 200 products. If you want to use all of your old devices, dual-mesh, and reliability, INSTEON is ideal for you.
- Universal Powerline Bus (UPB)
UPB, as the name states, uses electrical wirings to transmit data to devices and so does not need a host or a central hub as it allows peer communication. UPB uses pulse-position modulation to communicate with other UPB devices.
The advantage of UPB is that no extra wiring is necessary as it uses existing electrical wiring. Also, it is less expensive and is reliable and allows two- way communication amongst peers.
You can also make use of the Wi-Fi you have at your home. So you can avoid any extra cost of installing wires or a central hub. You can simply connect devices with your Wi-Fi password.
The problem with this sort of connection is that more devices that you have connected with your Wi-Fi, the slower will be the response of the smart home devices. Also, it requires a lot of power and so might drain the battery of other networked devices faster than other systems.
Another wireless technology is Bluetooth that is already used by some manufacturers in light bulbs and smart door locks. Unfortunately, Bluetooth can only be used for short-distance communication, but it is a technology-based on secured encryption. Its wireless feature, combined with the simplicity of use, indicates that more smart home products will have Bluetooth in the future.
To sum up, technology has advanced to a point where you can save yourself from menial tasks such as switching on lights or manually closing garage doors.
While you still can’t get the house shown on The Jetsons or Back to the Future II, multitudes of smart home devices of Z-Wave will simplify and secure your home life significantly.
