About bridges
What are smart home hubs?
Hubs and bridges are the radios that talk to non-Wi-Fi devices and translate them onto your home network. A Zigbee or Z-Wave bulb can't reach your phone directly. It needs a hub that speaks both Zigbee/Z-Wave and Wi-Fi/Ethernet. Some hubs are vendor-locked (Hue Bridge, IKEA DIRIGERA, Aqara M3), some are open and protocol-agnostic (Home Assistant, SmartThings).
This category includes Zigbee coordinators (Hue Bridge, Sonoff ZBDongle, SLZB-06M, IKEA DIRIGERA), Z-Wave controllers (Aeotec Z-Stick, Zooz ZST10), Thread border routers (Apple TV/HomePod, Nest Hub, Aqara M3), multi-protocol hubs (Home Assistant Yellow, SmartThings Station), and vendor-specific gateways (Lutron Caseta SmartBridge, Lutron RA2 Select, Bose Music Hub).
Which protocols do hubs support?
A typical hub exposes one or more of: Zigbee (~90% of dedicated bulb-and-sensor ecosystems), Z-Wave (mains-powered switches and locks, especially in North America), Thread (low-power IPv6 mesh used by Matter), and Matter (vendor-neutral application layer that can run over Wi-Fi or Thread).
For most users, the right answer is Home Assistant + a Sonoff ZBDongle-E or HA SkyConnect as a starter Zigbee/Thread combo, or a HomePod mini / Apple TV if you're already inside Apple Home and just need a Thread border router.

Frequently asked questions
Do I need a hub to use a smart home?
If you stick to Wi-Fi or Matter-over-Wi-Fi devices, no. As soon as you add Zigbee, Z-Wave or Thread devices, you need at least one hub or USB coordinator. Even all-Wi-Fi setups benefit from a local hub like Home Assistant for reliability when the internet drops.
What is a Thread border router?
A Thread border router bridges Thread (a low-power mesh used by many Matter devices) to your Wi-Fi network. Common ones live inside an Apple TV 4K, HomePod mini, Google Nest Hub (2nd gen), Amazon Echo (4th gen+) and Aqara M3. You usually have one already without realizing it.
Should I pick Zigbee, Z-Wave or Matter for a new install?
For a new install starting today, Matter-over-Thread is the safest long-term bet: vendor-neutral, works across Apple/Google/Alexa, and the ecosystem is expanding fast. Zigbee remains the strongest for cheap, varied lighting and sensors. Z-Wave excels for North American mains-powered devices (switches, locks).
Can one hub replace several?
Often, yes. Home Assistant with a multi-protocol stick (HA Yellow, SLZB-06M, ZBT-1) handles Zigbee, Thread and Matter on a single device, with optional Z-Wave via a second USB stick. SmartThings and Aqara M3 also expose multiple protocols from one box. The trade-off is reliability: when one combined hub fails, everything goes down.
