Thread Border Routers Explained: What They Do and Which Devices Have One

What Thread is

Thread is a low-power wireless mesh network built on IPv6 and maintained by the Thread Group. It is one of the networks Matter runs on, alongside Wi-Fi and Ethernet. Thread suits devices that run on batteries or send small amounts of data, such as door and window sensors, motion sensors, locks and buttons, and it is also used by some bulbs and plugs.

In a Thread mesh, plugged-in devices such as plugs and bulbs usually act as routers: they pass messages along and extend the network. Battery-powered devices usually do not route traffic, so they can sleep and save power.

What a Thread border router does

A Thread border router connects the Thread mesh to the rest of your home network over Wi-Fi or Ethernet. Without one, your phone, your smart speaker and your platform's automations cannot reach Thread devices. A Matter device that uses Thread needs at least one border router in the home. Matter devices that use Wi-Fi do not need one.

Being a border router is a different job from being a Matter controller, the hub that adds and runs devices in Apple Home, Google Home, Alexa or SmartThings. Many smart speakers, displays and streaming boxes do both, but not all of them. Nanoleaf says its panels' border routers do not act as a home hub, and some Google speakers are Matter hubs for Wi-Fi devices only. Our hubs and bridges guide explains the controller, border router and bridge roles.

Devices that include a Thread border router

These lists come from each maker's documentation, checked on October 1, 2026. Models and software change, so check the linked page for your exact device.

Apple

Apple lists the Apple TV 4K (3rd generation) Wi-Fi + Ethernet, Apple TV 4K (2nd generation), HomePod (2nd generation) and HomePod mini as Thread-enabled home hubs. The Wi-Fi-only Apple TV 4K (3rd generation) is not on that list. Apple also says that with iOS 18, iPhone 15 Pro and later models can control Thread accessories without a home hub, although it still recommends setting one up.

Google

Google's Matter hub list names the Google Home Speaker (2026), Nest Hub (2nd gen), Nest Hub Max, Nest Wifi Pro (Wi-Fi 6E) and Google TV Streamer (4K) as hubs that also support Thread. The Nest Mini, Nest Audio and Nest Hub (1st gen) are Matter hubs for Wi-Fi devices only. Source: Google Nest Help: Matter hubs.

Amazon

Amazon's developer documentation lists a built-in Thread border router in the Echo (4th Gen), Echo Hub, Echo Show 10 (3rd Gen), Echo Show 15 (2nd Gen), Echo Show 21 and several 2025 models, including the Echo Dot Max, Echo Show 8 (3rd Gen, 2025 release) and Echo Studio (2025 release). Many eero routers are on the list too, including the eero 6 and 6+, eero Pro 6 and Pro 6E, and the eero 7 family. Source: Amazon: smart home Thread support.

Samsung SmartThings

SmartThings' Matter overview (April 2023) says the latest SmartThings Hub, the SmartThings Station, Samsung TVs and Samsung Family Hub refrigerators have Thread border routers built in. The article describes recent models, so check your exact TV or refrigerator in the SmartThings app. Source: SmartThings: everything you need to know about Matter.

Nanoleaf

Nanoleaf says its Shapes, Elements and Lines panels can act as Thread border routers with current firmware, and that they do not act as a home hub, so you still need a Matter controller from your platform. Nanoleaf's list covers the panels only; Essentials bulbs and light strips are Thread accessories, not border routers. Source: Nanoleaf Support: Nanoleaf Thread border routers.

Stand-alone hubs

These hubs in our catalog are Thread border routers according to their makers. Each entry quotes the maker's page, linked after the quote.

• Aqara Hub M3: "This enhancement makes the M3 a versatile Matter controller and Thread Border Router" (Aqara).
• Aqara Hub M100: "Aqara Hub M100 acts as a Thread Border Router and a Mesh Extender" (Aqara).
• Aqara Hub M200: "The M200 acts as a Thread border router, bridging it to your Wi-Fi or Ethernet network" (Aqara).
• Aqara Thermostat Hub W200: "It also acts as a Thread Border Router and Mesh Extender to increase the coverage, speed, and reliability of your Thread network" (Aqara).
• IKEA DIRIGERA hub: "DIRIGERA includes Thread Border Router functionality to support them" (IKEA).
• Aeotec Smart Home Hub (works as a SmartThings hub): "Aeotec Smart Home Hub acts as border router in the Smart Home Thread network" (Aeotec).
• MOES Matter Wired Gateway (MZHUB-MS): "It features a built-in Thread Border Router and Matter certification" (MOES).

Popular hubs that are not Thread border routers

A Matter hub or bridge is not automatically a Thread border router. We checked each device below against its maker's documentation, and none of them is documented as one. Most are Matter bridges that bring the maker's own Zigbee, Wi-Fi or Sub-1G devices into your platform, so a Matter device that uses Thread still needs a border router from the lists above.

• Aqara Hub M2: no Thread radio; Aqara lists Zigbee 3.0, infrared, Bluetooth LE and Wi-Fi (Aqara).
• SwitchBot Hub 2: a Matter bridge for SwitchBot devices, over Wi-Fi (SwitchBot).
• SwitchBot Hub 3: SwitchBot describes a Matter bridge with Wi-Fi and Bluetooth LE, with no border-router claim.
• SwitchBot AI Hub: SwitchBot names a Matter bridge only.
• Philips Hue Bridge: a Matter bridge for Hue lights and accessories (Philips Hue).
• SONOFF Zigbee Bridge Ultra: a Matter bridge for supported Zigbee devices (SONOFF).
• Google Nest Learning Thermostat (4th gen): a Matter thermostat that is not on Google's Thread border router list (Google).
• Bosch Smart Kitchen Dock: a Matter bridge with Wi-Fi and Bluetooth; the Bosch and Home Connect pages list no Thread (Home Connect).
• ORVIBO MixPad X: ORVIBO describes a Zigbee gateway, with no Thread border router claim.
• ORVIBO MixPad 7: ORVIBO lists Zigbee, Wi-Fi, Bluetooth and Ethernet, and no Thread.
• SONOFF iHost: Zigbee, Wi-Fi and Bluetooth only, as shipped.
• SONOFF Bridge Max: a Matter bridge and Zigbee gateway, with no Thread.
• SONOFF NSPanel Pro: Wi-Fi and Zigbee radios only.
• TP-Link Tapo H500 Smart HomeBase: TP-Link says "The Tapo H500 does not support the Thread protocol" (TP-Link).
• Tapo H200 Smart Hub: 2.4 GHz Wi-Fi and Sub-1G, with no Thread.
• Tapo H100 Smart IoT Hub: Sub-1G and 2.4 GHz Wi-Fi, with no Thread.
• Tapo H110 Smart IoT & IR Hub: Wi-Fi, Sub-1G and Bluetooth (for setup only), with no Thread.

We could not confirm these either way, because no maker page we found says whether they are border routers:

• Aqara Camera Hub G350: Aqara pages list a Zigbee/Thread radio and a Matter controller, but none says Thread border router.
• Tuya Smart M Gateway THP23-ZB-X: No official Tuya page for this model states Thread border router.
• geo SeeZero Display: No border-router wording on geotogether.com.

How many border routers do you need?

One is enough to start. Matter 1.4.2 requires Thread border routers certified under it to support at least 150 devices, more than most homes use (CSA: Matter 1.4.2). A second border router can keep Thread devices reachable if the first goes offline, as long as both are on the same Thread network.

That condition matters when you mix ecosystems. Adding a border router from another company has often created a second Thread network, splitting your devices between two meshes that cannot use each other's border routers. Thread 1.4 added credential sharing, so border routers from different makers can join one network (Thread Group: Thread 1.4 features white paper). Whether a given border router supports it depends on the device and its firmware, so check the maker's notes.

Before you buy a Thread device

1. Check that you have a border router from the lists above, or plan to add one.
2. Check that your platform's Matter controller is set up. A border router alone does not add devices to your app.
3. Check the product page for the network: Matter over Thread needs a border router, Matter over Wi-Fi does not.
4. Keep Bluetooth on during setup; most Matter devices use it to join. Matter 1.4.1 and 1.6 add NFC options for some products.
5. Put the border router somewhere central, and remember that plugged-in Thread devices extend the mesh while battery devices do not.

How we wrote this

This explainer is based on the manufacturer and standards documentation linked above, checked on October 1, 2026. An earlier version of this post listed every Apple TV 4K from the 2nd generation on as a border router and advised that more border routers always help; both statements were too broad and are corrected above. On October 5, 2026 we added the stand-alone hubs, the hubs that are not border routers and the ones we could not confirm, from the catalog's review of each maker's pages (checked October 1, 2026). MatterCatalog does not test devices; see our editorial policy.
