Google Home: Matter hubs, Thread border routers, IPv6 and sharing devices

What Google Home is

The Google Home app sets up Google’s own speakers, displays and routers, and adds Matter devices and “Works with Google Home” devices from other makers. Google says more than 80,000 of those work with it.

Matter devices need a hub for Google Home: a Google speaker, display, Nest Wifi Pro, Google TV Streamer or a compatible TV. A Google hub needs no special setup. Once it is in the app and on your Wi-Fi, it updates itself and starts working as a hub.

Supported Matter device types and features differ by platform; check Google’s compatibility list. Its Wi-Fi or Thread logo tells you which network it uses. Thread devices also need a hub that is a Thread border router before setup can finish.

Hubs and Thread border routers

For a compatible non-Google hub, follow its maker’s setup instructions. Google says each Matter app needs a hub compatible with that app.

What it needs from your network

Google’s help pages say nothing specific about VLANs or multicast settings for Google Home.

• IPv6: Google says IPv6 must be on in your home Wi-Fi before you add Matter devices. Without it, setup may seem to work but control fails later. Some devices fall back to IPv4, but still need IPv6 to talk to every Matter app and device. Your router’s manual or your internet provider can tell you how to turn it on.
• Same network: keep your phone on the same Wi-Fi network as your Google speaker or display while setting up.
• No client isolation: Google says to turn off AP isolation, also called “client isolation” or “guest mode”, so smart devices can reach your speaker or display. Guest networks often have it on.
• 2.4 GHz: if a device won’t set up across bands, put the speaker or display and your phone on the 2.4 GHz network, then add the device.
• Local network access on iPhone: allow it for the Google Home app.
• Thread: a border router links Thread devices to your Wi-Fi. It forwards only Thread traffic and announces Thread devices over mDNS, so phones and hubs can find them.

Matter, and sharing with other apps

1. Put the device in pairing mode, as its maker describes.

2. Open Google Home and tap Devices › Add › Matter-enabled device, or tap the pop-up that appears.

3. Scan the Matter QR code from about 12 cm away.

4. If the code won’t scan, tap Set up without QR code and type the setup key.

5. Choose a room and a name when it connects.

Share a device with another Matter app

1. Install the other app first.

2. In Google Home, tap Home › All devices and touch and hold the device tile.

3. Tap Settings › Linked Matter apps and services › Link apps and services.

4. Choose the other app; Google Home opens it and passes the device on.

5. Or tap Use pairing code or Share with QR code and enter that in the other app.

Bring in a device from a maker’s app

If you set the device up in its maker’s app, accept that app’s prompt to share it with Google Home, or follow its instructions to do so.

Common problems and Google’s fixes

Matter setup freezes or never finishes

1. Restart the Matter device, as its maker describes.

2. Close the Google Home app.

3. On Android, clear its cache in Settings › Apps › Google Home › Storage and cache.

4. Restart your phone, open Google Home and start setup again.

5. If it still fails, factory reset the device and set it up again.

Other messages

• Error adding from the maker’s app: check that a compatible hub is set up in Google Home.
• Works at first, then can’t be controlled: check that IPv6 is on in your router.
• Thread device won’t finish setup: add a hub that is a Thread border router, from the table above.
• Speaker or display can’t find a device: turn off client isolation on the router or extender, or try 2.4 GHz.

Move a device to another home

1. Hold the device tile and tap Settings › Remove device.

2. Factory reset the device.

3. Switch homes and add the device again. Its automations and routines don’t move with it.
