How to Add a Device to Google Home: Step-by-Step

To add a device to Google Home, open the Google Home app, tap the add (+) button, choose how you want to pair the device, and follow the on-screen prompts. The exact path depends on the device type: a Matter device scans a QR or numeric code, a Google-branded Nest device is detected automatically, and many older Wi-Fi gadgets link through their own manufacturer app first. This guide walks through each route and what to do when pairing stalls.

Before you start: what you need

Adding a device goes faster when the basics are in place. Google Home assumes your phone and the new device are on the same network and that you're signed in with the Google account that will own the home.

Two requirements trip people up most often. First, Bluetooth: Google Home uses it to discover and hand off credentials to many devices during setup, so leave it on even if the device itself runs on Wi-Fi. Second, the 2.4 GHz band. A large share of smart-home devices connect only on 2.4 GHz, and if your phone is locked to a 5 GHz network during setup, the handoff can fail. If you hit a wall here, our guide on smart devices that won't connect to Wi-Fi during setup covers the band issue in depth.

How to add a device (the general flow)

Every device starts the same way, then branches based on type. Here's the core sequence.

1. 1Open the Google Home app and tap the add (+) button
2. 2Choose “Set up a device”
3. 3Pick “New device” (Google/Matter) or “Works with Google” (third-party account)
4. 4Follow the prompts to scan a code or link an account
5. 5Assign the device to a home and a room

1. Open the Google Home app and make sure the correct home is selected at the top.
2. Tap the add (+) button, then choose the option to set up a device.
3. Pick the right category. "New device" is for Google Nest products and Matter devices you're setting up for the first time. "Works with Google" (sometimes shown as "Already set up?") is for linking a third-party account such as Philips Hue, Govee, or TP-Link.
4. Complete the device-specific steps below.
5. Name the device and assign a room. Rooms matter more than they look — they're how you say "turn off the living room lights" and how the app groups controls. Putting devices in the wrong room is the most common reason voice commands miss.

Adding a Matter device

Matter is the cross-platform standard that lets one device work across Google Home, Alexa, and Apple Home. If your device shows a Matter logo, setup is consistent and code-based.

1. In the Google Home app, tap add (+) and choose to set up a new device.
2. When prompted, scan the Matter QR code on the device or its packaging, or enter the 11-digit numeric setup code manually.
3. Google Home commissions the device onto your network and Matter "fabric." For Wi-Fi Matter devices this uses your 2.4 GHz network; for Thread-based Matter devices, it routes through a Thread border router you likely already own.

If you want the same Matter device controllable in more than one ecosystem at once, that's handled through Matter multi-admin, which shares a new pairing code rather than re-running setup. For the broader picture, see our walkthrough on adding a Matter device to Alexa, Google, or Apple Home.

Adding an older Wi-Fi device ("Works with Google")

Plenty of devices predate Matter and connect through the manufacturer's own cloud. For these, you set the device up in its own app first, then link that account to Google Home.

1. Set up the device fully in the manufacturer's app (for example, the Kasa, Wyze, or Hue app) so it's online and controllable there.
2. In Google Home, tap add (+), choose "Works with Google," and search for the brand.
3. Sign in to your manufacturer account when prompted. Google Home then imports the devices and you assign rooms.

Matter vs. "Works with Google" linking

Knowing which path your device uses saves time. Here's how the two compare.

Factor	Matter device	Works-with-Google device
Setup trigger	QR / 11-digit code	Account sign-in
Needs vendor app?	No (optional for firmware)	Yes, first
Cloud dependency	Local control possible	Vendor cloud required
Multi-ecosystem	Yes (multi-admin)	Re-link per platform

When the device won't pair

Most failures fall into a handful of buckets. Work through these in order before factory-resetting anything.

• Device not in pairing mode. New devices usually advertise automatically; ones being re-added often need a manual reset (commonly a long button press). Check the manufacturer's instructions for the exact reset.
• Wrong Wi-Fi band. If your router broadcasts one combined network name, temporarily separate the 2.4 GHz band or move your phone onto it during setup.
• Phone and device on different networks. Guest networks, VPNs, and work profiles all block discovery. Put both on the same primary network.
• Bluetooth off. Re-enable it; Google Home relies on it for discovery and credential handoff.
• Matter code rejected. If a device was previously commissioned elsewhere, it may need a reset or a fresh multi-admin code rather than the original printed code.

If a device pairs but then drops offline repeatedly, the cause is usually network coverage or interference rather than Google Home itself — and that's worth ruling out before assuming the integration is broken.

Frequently asked questions

Do I need a Google Nest speaker or hub to add devices?

No. The Google Home app on your phone is enough to add and control devices. A Nest speaker or display adds voice control and, in some models, acts as a Thread border router or Matter controller — useful, but not required just to pair a device.

Why doesn't my device show up under "Works with Google"?

Either the brand doesn't offer a Google integration, or the device hasn't been set up in its own app yet. Confirm it's online and controllable in the manufacturer's app first, then search the exact brand name in Google Home. If it's a Matter device, use the code-based "New device" path instead.

Can the same device live in Google Home and Alexa at once?

Yes, if it supports Matter. Through multi-admin, you generate a fresh pairing code in one app and use it to add the device to the second platform. Non-Matter devices generally require linking each account separately. Deciding between platforms? See Alexa vs. Google Assistant for your smart home.

What's the difference between Matter and Thread here?

Matter is the application standard that defines how devices and platforms talk; Thread is one of the networks Matter can run over (alongside Wi-Fi and Ethernet). A Thread device needs a border router on your network. Our explainer on Matter vs. Thread breaks down where each fits.
