When you directly compare Wi-Fi plugs with Z-wave Plugs, Wi-Fi Bulbs with ZigBee Bulbs, and Wi-Fi light switches with Z-Wave light switches, you see a noticeable difference in price. In keeping with the low barrier of entry, Wi-Fi devices often cost less than their Z-Wave and ZigBee counterparts. Wi-Fi Devices Are Typically Less Expensive TP-Link That familiarity gives them a leg up in learning to interact with your smarthome. It’s more likely your family and friends have encountered the Google Assistant or Alexa app than a more esoteric smart hub app. When you do need something more complicated, IFTTT and Yonomi work well with Alexa (but not Google, unfortunately). While Google Assistant and Alexa routines aren’t as powerful as some smart hubs, they’re good enough for the average smarthome. You can pair them with Alexa or Google Assistant, which are designed to be as user-friendly as possible. But that’s not necessarily the case with Wi-Fi devices. Unfortunately, that’s unavoidable because they’re incredibly powerful and capable of advanced automation.

Smart hubs can be a challenge to learn how to use. Wi-Fi Devices Have a Lower Barrier of Entry If that fails, either because the company quits or it just breaks, your whole smarthome goes with it. ZigBee and Z-Wave, though, have a giant and singular point of failure: the hub you use to control them. With Wi-Fi, anything in your smarthome can break which, in turn, can lead to everything in your smarthome breaking. Insignia branded plugs, lightbulbs, and even a smart freezer all lost their smarthome capabilities. We saw this recently when Best Buy chose to leave the smarthome business. This means if either side calls it quits, your device does, too. But unlike a smarthome hub, Alexa and Google Assistant don’t control Wi-Fi devices directly-the various clouds talk to each other. And if you control your smarthome with Alexa or Google, their cloud is involved, too. The manufacturer of the gadget provides a cloud and a dedicated app. Wi-Fi devices, on the other hand, depend on multiple clouds. Your hub does all the work, so if the company that manufactures your Z-Wave lightbulbs or ZigBee smart locks quits, your devices will keep working. Z-Wave and ZigBee Are Single Points of Failure Alexander Kirch/ShutterstockĮven when you use a cloud-dependent hub, like Wink or SmartThings, Z-Wave and ZigBee products benefit from company clouds involved in the process. Z-Wave avoids this problem entirely as it only has to contend with itself, even if you add more and more Z-wave devices. It’s easy for the 2.4 GHz spectrum to get crowded and suffer issues. That’s because Z-Wave runs on a different radio frequency-908.42 MHz-while both ZigBee and most Wi-Fi smarthome devices communicate over 2.4 GHz. are less prone to interference issues than either Wi-Fi or ZigBee. You’ll notice a dramatic difference between the time you send a command and it happens, like turning on the lights. And when you control your smarthome locally, it also works faster. This means that even when the internet is down, you can still control your smarthome. You need dedicated apps, and the closest you can get to a centralized experience is syncing your devices with Alexa or Google.īut with the right hub, like Hubitat, Homeseer, or OpenHab, you can create a smarthome that doesn’t rely on the cloud. All Wi-Fi smarthome gadgets depend on the cloud to work. When you build a smarthome, you have to ask yourself how much you want the cloud involved.

But not all things are equal between the protocols. Now, for every Z-Wave Lock on the market, there’s a Wi-Fi alternative, often from the same manufacturer. It seemed that every smarthome manufacturer touted Google and Alexa integration, and focused on Wi-Fi radios instead of Z-Wave or ZigBee. Wi-Fi devices didn’t have much support or centralized hubs to tie all the gadgets together.īut that changed this year-a fact that was evident at CES. And most smart hubs support both, so, when necessary, you could use both in your home. You picked a protocol and tried to stick with it. Until recently, if you wanted a smarthome, either Z-wave or ZigBee was your best bet. We even warned that Google and Amazon were trying to kill the smarthome hub and covered the difficulties you might encounter with dozens of Wi-Fi devices. But in the past, Wi-Fi as a total smarthome solution wasn’t a serious consideration. We’ve written a great deal about Z-Wave and Zigbee, what each protocol does, and why you would pick one over the other.
