Smart Home Technologies: The Complete Guide to Z-Wave
Table of Content
Many, but by no means all, of them can work together, making the process of building out your smart home infrastructure even more complicated. One of ZigBee’s primary strengths is its security, having been built around the kind of encryption used in banks and other financial institutions. Like Z-Wave, ZigBee utilizes a controller hub that provides for easier configuration and management, and in fact many hubs support both ZigBee and Z-Wave protocols. Z-Wave is great for low-power battery-operated devices like remote controls, motion sensors, smoke detectors, and thermostats.
I previously managed the consumer electronics reviews team, and before that I covered mobile, smart home, and wearable technology for PCMag and Gigaom. We've tested all the top professional-install and DIY home security packages to help you decide which one is right to protect your family and your property. Thirdly, Bluetooth for one-off devices that are connecting to your phone.

The protocol supports data rates of up to 250 kbps and can operate in the 2.4 GHz frequency. It has strong interoperability capabilities with up to 65,000 devices per network. It also supports secure data transmission via AES-128 encryption, making it a great choice for complex smart home systems. With Z-Wave LR, a single smart home network can support up to 4,000 devices. The protocol also leverages a dynamic power control feature to offer up to 10 years of battery life on a coin-cell battery.
Wi-Fi is not great for battery-powered devices such as smart locks, smart sensors that need to remain on for years at a time, or tracking data. Low-bandwidth protocols like ZigBee or Z-Wave have several advantages, especially in power-constrained applications. While offering device interoperability, connection to the internet among these devices requires an additional hub.
What is Zigbee
Most video doorbells use your existing doorbell wiring (two low-voltage wires) and are fairly easy to install, but battery-powered models install in minutes. Some work with other smart devices such as door locks and sirens, plus support IFTTT and Alexa voice commands. Anoutdoor camerais ideal for keeping an eye on what's happening outside of your home. These devices are weatherproof and typically require a nearby ground fault circuit interrupter outlet to supply power, although a handful of battery-powered models are also available.
Having multiple smart home devices spread across different applications in the home quickly becomes a lot to manage. Different control/interface for each application wears out the user and prevents the attainment of the level of sync that should exist among smart home applications to make the home truly smart and autonomous. Devices used in Smart Home applications are usually either plugged-in or battery-powered. With power consumption being a major constraint for most of the protocols, how the device is powered is always a major contributor to the choice of protocol. Developed by the Bluetooth special interest group, BLE , also referred to as Bluetooth Smart, is a modification to the Classic Bluetooth protocol with low power consumption as one of its major focuses. It's a product of the desire to reduce the amount of power consumed by devices, both when transmitting data and when idle, to ensure longer battery life.
How Wi-Fi Works with Your Smart Home Devices

Thread uses a 2.4 GHz frequency, which is the same as Zigbee and Bluetooth. As part of the consulting body that developed Matter, DigiCert has played an integral and foundational role in establishing the security standards built into Matter. And DigiCert was the first CA to be approved by the CSA as a trusted root for issuing DACs.
First, you may be able to install a firmware update to some Zigbee devices that converts them to Matter. The availability of a reference software implementation of Matter should speed up development of Matter based IoT devices by manufacturers. IoT devices that communicate using Matter where scheduled to begin appearing on the market in time for the holiday shopping season. However, the CSA recently announced a delay until the first half of 2022. An easy-to-understand use case for Sidewalk is a dog with a Sidewalk-enabled tracker escapes from its owner’s backyard.
Engineered with proven technologies, Matter helps manufacturers speed time-to-market while delivering best-in-class devices that work with any connector. For both manufacturers and consumers, Matter makes a better product and a better user experience. System supports up to six cameras subject to sufficient WiFi speeds. Without a Vivint services plan, product and system functionality is limited .
Instead, UPB devices only communicate with other devices on the Universal Powerline Bus standard. UPB hardware connects with a home controller and manufally configured links for each networked device. This powerful communication technology is capable of delivering fast, bidirectional, IP-based communication over any wire. It enables consumers to use existing electrical wiring to communicate over existing wires (twisted pair, powerline, phone lines, coax, etc.). Additionally, it includes a convenient bridging functioning that enables it to connect to Ethernet and wireless networks (WiFi, BLE, etc.) with easy.
Matter (originally called Connected Home over IP ) is the newest protocol for IoT wireless communications. It promises to be a unifying standard that will allow all IoT devices to work together. If you think that Matter will just be another competing standard that confuses consumers and complicates smart homes, you are probably wrong. It is a layer that is designed to sit on top of communications protocols and allows IoT devices to talk to each other. So, two devices that implement DotDot will be able to communicate even if one device connects to a hub using Zigbee and the other connects to the hub using Wi-Fi.
I want to thank Johan Pederson, manager, product marketing – smart home & consumer IoT at Silicon Labs for his help with this article. Another common way to implement a Z-Wave smart home system is through your home security system. Many home security systems build Z-Wave functionality into their control panels or base stations. Popular companies like ADT, Vivint, and Ring Alarm all offer Z-Wave integrations.
In many homes, devices are largely disconnected from one another, meaning the experience is not as seamless, and their smart capabilities are not being fully used”. However, the existence of hubs further revealed the interoperability challenges that have plagued smart home systems due to the multiple protocols. Wireless protocols are increasingly common, but wired options remain reliable as well. Zigbee and Z-Wave are among the best-used, with adopters such as Wink and SmartThings. Z-Wave lends the best device compatibility with its guaranteed interoperability, though Zigbee presents secure, reliable, low-energy wireless communication. Unfortunately, with this varied group of smart home protocols comes stratification.
