Thread Border Routers Explained: Why They Matter for Matter

Thread is the backbone of many Matter devices. Learn what Thread border routers do and which ones to buy.

What Is Thread?

Thread is a low-power, mesh networking protocol designed specifically for smart home devices. It's one of the key transport layers for Matter — many Matter devices use Thread to communicate.

What Is a Thread Border Router?

A Thread border router connects your Thread mesh network to your home IP network (Wi-Fi/Ethernet). Without one, Thread devices can't communicate with your phone, voice assistants, or the internet.

Which Devices Are Thread Border Routers?

You might already own one! These popular devices include built-in Thread border routers:

Apple TV 4K (2nd gen and newer)
Apple HomePod (2nd gen) and HomePod mini
Google Nest Hub (2nd gen) and Nest Hub Max
Google Nest Wi-Fi Pro
Amazon Echo (4th gen)
Samsung SmartThings Station
Nanoleaf Elements and Shapes panels
eero Pro 6E and eero 6+

How Many Do You Need?

For most homes, 2-3 Thread border routers provide excellent coverage. Thread's mesh networking means each device extends the network, but border routers are the connection points to your main network.

Pro Tips

Spread them out — place border routers in different rooms for better coverage

More is better — Thread auto-optimizes routing, so extra border routers only help
