Matter, Zigbee, or Wi-Fi? Standards Explained

“Will this work with my Alexa?” is one of the most common questions when buying smart home devices. Behind this lies a bigger question: Which standard is in the device, and what does that mean for expandability later?

Wi-Fi: The Easiest Entry

Most inexpensive entry-level products, including the TP-Link Tapo P110 (4er-Pack), connect directly to your home Wi-Fi – without an additional hub. This makes setup straightforward. Since the devices use the Wi-Fi router directly, a large number of devices can increase the router’s load. However, this is rarely a real problem in practice when starting with a handful of outlets or a camera.

Zigbee: More Devices, a Hub Needed

Zigbee devices don’t communicate directly with the router, but via their own radio bridge (hub), which is in turn connected to the Wi-Fi. The advantage: Dozens of devices hardly burden the home network, and the radio standard is optimized for low power consumption – ideal for battery-powered sensors. The disadvantage: Without a suitable hub (often tied to a specific brand), nothing works.

Matter: An Attempt to Unify Everything

Matter isn’t a radio standard like Zigbee, but a common “language” that is intended to allow devices from different manufacturers to communicate with each other and with Alexa, Google Home, or Apple Home simultaneously – without having to commit to an ecosystem. In practice, implementation is still inconsistent: Some manufacturers provide Matter support retroactively via updates, others don’t.

Our Assessment for Getting Started

If you’re switching a lamp or outlet smart for the first time, you’ll reach your goal fastest with simple Wi-Fi devices and won’t spend money on a hub that you might not even need. Only when you notice that more than about ten devices should be added or the Wi-Fi noticeably slows down, should you consider a Zigbee system with a hub.
