The whole reason for getting a hub like Wink or SmartThings is to be able to use one app for all your devices. If you’ve been around smart home automation for any length of time you’ve seen a few hubs come and go. Part of the downside to these hubs, even SmartThings and Wink is they rely on cloud servers to work. If Wink or SmartThings would go out of business, the app or the hub would no longer work. Z-wave to the rescue. Hub’s support a ton of different smart home technologies and companies, from Z-Wave to ZigBee, even Nest and Phillips Hue. The upside to Z-Wave is the fact that it’s a common standard. Even if Wink and/or SmartThings stop working, if your devices are Z-Wave the chances of you finding another way to control them is huge.
One of the best features of Z-Wave is the fact that all most devices have antenna’s that extend the network. So even if you have switches or other devices far from the hub, they are likely to still work well if you have a multitude of other devices in your house. Having trouble with a device not wanting to work? Chances are that if you put more devices in your home, that one that is further from the hub will work much more reliably.
Z-wave devices take much less energy than ones that need Wifi or other wireless technologies. This means any battery-operated devices like motion detectors or water sensors will have to have batteries changed much less often.
