Google Home seamlessly brings together all of your compatible smart devices made
by Google and thousands of your favorite Works with Google Home and
Matter partner brands.

When certifying with us, we make sure you're also certified with
[Connectivity Standards Alliance (Alliance)](https://csa-iot.org/certification/why-certify/),
who create and promote universal, open standards that enable products to
securely connect and interact.

## Why certify Matter

Certification allows the use of Certified Product logos and listing of the
product on the Alliance website for verification. Certification denotes
compliance to a specification and shows interoperability in the respective
program.

- Lowers barriers to market entry with access to a vast technology ecosystem.
- Allows for use of exclusive Alliance certified product logos and a product listing on the Alliance website.
- Confirms compliance to Alliance specifications with testing from experienced professionals.

## Why certify your Matter device with Google

When you certify your Matter device with Google, you'll be
able to:

- Use the "Works With Google Home" badge on the package for promotion.
- Use developmental support tools such as [Matter Virtual Device](https://developers.home.google.com/matter/tools/virtual-device.md.txt).
- Set up custom images during commissioning flows.
- Use the [OTA](https://developers.home.google.com/matter/ota.md.txt) functionality in Google Home Developer Console.
- Be featured in the [Explore Devices](https://home.google.com/explore-devices/) section of the Google Home site.

## WWGH badge certification

The Works with Google Home (WWGH) badge is issued to devices that have passed
Google's certification, regardless of the connection type
(Matter, Cloud-to-cloud,
Local Home SDK).

Google-certified Matter devices can use
WWGH badge along
with the Alliance's Matter badge, giving
consumers confidence that the device will work well with Google Home ecosystem.
With the WWGH badge, customers can identify that
Matter devices work seamlessly with Google Home. After your integration has been
approved and verified, visit the
[Partner Marketing Hub](https://partnermarketinghub.withgoogle.com/signup/)
to get WWGH badge assets for use with your device.
