Philips Hue vs. Z-Wave: Important considerations when choosing a smart lighting platform

Between ZigBee and Z-Wave, Philips Hue and LIFX, and any number of other platforms, frameworks, and products, it can be tough trying to determine what's right for you. If you find yourself stumped and unsure of which smart bulb, bridge, or hub you should get, this one's for you!

Understanding smart home protocols

Before we dig in to the meat of the comparison, let's take a closer look at the Philips Hue lighting system and the Z-Wave protocol. Firstly, it's important to understand that Philips Hue bulbs communicate using the ZigBee wireless protocol. That means I'll actually be comparing ZigBee and Z-Wave in this guide.

Some smart accessories communicate using more familiar methods like Wi-Fi and Bluetooth. When you open an app and toggle the power on your Bluetooth smart plug, your command is sent over Bluetooth to the plug and it toggles the power. When you open an app and adjust the color of your Philips Hue bulbs, your command is sent over your Wi-Fi router to the Philips Hue Bridge. The Philips Hue Bridge then uses the ZigBee wireless protocol to communicate with your bulbs, telling them to change their color to your specified settings. While Wi-Fi and Bluetooth are well known, relatively ubiquitous technologies, wireless protocols like ZigBee and Z-Wave have their benefits. Let's take a look at how they compare and contrast.

Mesh networking

ZigBee and Z-Wave are both mesh networking technologies. Instead of each individual device having to maintain a connection with your Wi-Fi network or proprietary bridge, the devices can communicate amongst themselves. You can think of it like a web (hence mesh) where each device is connected and communicating with all the other devices in the mesh network.

Most people won't run up against this limit, but it's worth noting that ZigBee supports far more devices on a mesh network than Z-Wave. ZigBee can support more than 64,000 devices on a single network. Z-Wave supports 232. This limit is much more of an issue for commercial properties. I'd like to meet the person who surpasses either of these limits in their home.

Communication and speed

ZigBee and Z-Wave use different frequencies for communicating with your smart devices. ZigBee operates on the 915Mhz band as well as the 2.4GHz band. Z-Wave, on the other hand, operates on the 908.4 MHz and 916 MHz bands. What does that mean in practice? Well, Z-Wave operates on sub-1GHz bands so devices are less likely to run up against interference from Wi-Fi and Bluetooth. Given that ZigBee operates on the 2.4GHz band — that's one of the bands on which your Wi-Fi operates — it is more likely to experience interference.

As for speed, Z-Wave's data rates top out at 100kbps. ZigBee can reach speeds more than two times that amount (~250kbps).

You shouldn't have to worry about this too much given that communication between devices is generally as simple as "turn to this color" and "turn off now." If you were sending huge chunks of data to your smart lighting on a regular basis, the differences would be more apparent.


Thanks to their mesh networking capabilities, range isn't too big an issue. As long as you've got enough individual devices across the network, they should be able to communicate with one another and their node (or bridge) just fine. That said, Z-Wave has ZigBee beat on range. The protocol can communicate with devices up to 100 feet away. ZigBee's reach is about half of that.


The Z-Wave protocol is a private technology licensed by SoC (system-on-a-chip) company Sigma Designs; ZigBee is an open protocol created and maintained by the ZigBee Alliance. Z-Wave says there are more than 2,100 certified products on the market — ZigBee touts about 2,500 certified products. Z-Wave's licensing requirements may be one of the reasons there are more ZigBee certified products on the market.

Here are a few products compatible with ZigBee:

  • Amazon Echo Plus - The $150 Amazon Echo Plus features a built-in ZigBee hub, giving you the power to control ZigBee certified products without having to buy a separate ZigBee bridge or hub.
  • Philips Hue Lighting - The $170 four-bulb starter kit (as well as any other Philips Hue lighting accessories) is controlled by the included Philips Hue Bridge. As I mentioned before, the bridge uses ZigBee to communicate with your Hue lighting.
  • Samsung SmartThings Hub - The $100 Samsung SmartThings hub is actually compatible with both ZigBee and Z-Wave. You can use the Hub to communicate with other Samsung SmartThings products as well as devices that support the ZigBee and Z-Wave protocols.
  • Wink Hub 2 - This $100 hub from Wink does not mess around. With support for Bluetooth LE, Z-Wave, ZigBee, Wi-Fi, Lutron Clear Connect, Thread, and Kidde, you're going to find quite the list of compatible products. The Wink Hub 2 is future-proofed and may be the best option for you if you're looking for a please-just-tell-me-what-to-buy ZigBee and Z-Wave hub.

Here are a few products compatible with Z-Wave:

  • August Smart Lock Pro - The $230 August Smart Lock Pro is a Z-Wave Plus product.
  • GE Smart Switches - GE has a line of smart switches ranging from $35 to $60 that can be controlled using the Z-Wave protocol.
  • Aeotec Multisensor 6 - This $60 multisensor from Aeotec packs in six sensors — motion, humidity, temperature, light, UV, vibration — that give you ultra-accurate, real-time readings of your home environment. Along with some of the more common sensors (motion, humidity, and temperature), this multisensor helps you keep track of potentially dangerous ultraviolet light in your home. This Z-Wave Plus certified device is small, unobtrusive, and perfect for anyone looking to add some automation to their smart home setup.
  • Samsung SmartThings Hub - (see above)
  • Wink Hub 2 - (see above)

Consider your options

There's quite a bit to consider when you start to dig in to the differences between wireless protocols. My advice? In practice, these tiny differences don't matter all that much in a typical consumer's smart home. The mesh networking capabilities of both protocols limit most issues with range. The simple communication between smart devices and their hubs limit most issues with speed. The massive number of smart devices on the market limits most issues with compatibility — if one type of smart bulb doesn't work for you, there are six more that will.
