What Is a Smart Home Hub?
A smart home hub is a central device that communicates with your smart home accessories and coordinates them. It acts as a translator between different wireless protocols (like Zigbee or Z-Wave) and your home network (Wi-Fi).
Whether you need a hub depends entirely on which devices and protocols you want to use.
When You Don't Need a Hub
Wi-Fi and Matter devices connect directly to your router. No hub required.
- Wi-Fi smart plugs (e.g. TP-Link Kasa, Shelly)
- Wi-Fi smart bulbs (e.g. LIFX, some Nanoleaf)
- Matter over Wi-Fi devices (e.g. newer Eve, Aqara M3 hub not required)
These devices connect like any other gadget on your network. The trade-off: Wi-Fi devices consume more power (fine for plugs, less ideal for sensors) and can congest your Wi-Fi network if you have many of them.
When You Do Need a Hub
Zigbee, Z-Wave, and Thread devices use their own radio frequencies and cannot connect directly to your Wi-Fi router. They need a coordinator or controller:
| Protocol | Hub / Coordinator needed |
|---|---|
| Zigbee | Zigbee coordinator (e.g. USB stick + Zigbee2MQTT, Hue Bridge, Echo 4th gen) |
| Z-Wave | Z-Wave controller (e.g. Aeotec Z-Stick, Hubitat, SmartThings) |
| Thread | Thread border router (e.g. HomePod mini, Apple TV 4K, Nest Hub 2nd gen) |
Which Hub Should I Get?
If you're starting fresh and want the widest compatibility: → A USB Zigbee dongle (e.g. Sonoff Zigbee 3.0 Dongle Plus) + Home Assistant. This gives you access to nearly every Zigbee device on the market.
If you want plug-and-play without a local server: → Amazon Echo 4th gen (has built-in Zigbee) for Zigbee devices, or go all-in on Matter/Wi-Fi devices.
If you're in the Apple ecosystem: → A HomePod mini serves as both a HomeKit hub and a Thread border router.
If you're invested in Z-Wave: → A Zooz Z-Box or Aeotec Z-Stick 7 with Home Assistant.
The Honest Answer
For a small setup with a handful of Wi-Fi or Matter devices: no hub needed.
For a larger setup with Zigbee sensors, battery-powered devices, and complex automations: yes, a hub (or Home Assistant) will make your life much easier, and give you far more control over your devices.
