What is Device Access and why are you launching it?

To live up to the commitments we published in May 2019, Device Access will ensure that your privacy and data safety come first while you seamlessly use Nest and Google products with our Device Access partners in your home.

Device Access lets qualified partners securely access and control your Nest products with their apps and solutions. This gives you more choice in how you control your home. We require Device Access developers to go through an additional security assessment to help keep your data private and secure.

How does Device Access ensure that my data is secure?

Device Access developers will have to have their proposed use case reviewed, pass an annual security assessment, and agree to our terms of service before they are approved, so we can help protect your data. 

To learn more about the annual security assessment, read our blog post about the Strobe OAuth Security Assessment.

How are Works with Nest, Works with Google Assistant, and Device Access different?

Works with Nest (WWN) was the original way that third party partners could access and control your Nest products. They were fully integrated with a Nest product and could check and change its status. Works with Nest connections will continue to work for those users who have a non-migrated Nest Account in the Nest app for as long as our partners support them. 

Works with Google Assistant (WWGA) enables the Google Assistant to control all your connected products. You can use the Google Assistant to create Assistant Routines in the Home or Assistant apps. We’ve announced two new aspects of WWGA specifically for the products in your home: Device Access and Home Routines. 

  • With Device Access, third party partners can directly access and control your Nest products, only after they pass a use case review from us and an annual security assessment from one of our authorized testers. For example, if you have a security system that offers a Device Access integration, you’ll be able to view and control your Nest camera and other products directly from your security provider’s app. Each year, they’ll be required to update their security assessment to validate that they continue to meet the security assessment requirements. Device Access allows you to integrate your partner products into your Google Nest ecosystem.
  • Home Routines allow your Nest and partner products to work better together and be more helpful. For instance, if your connected smoke alarm identifies an emergency in your home, a Home Routine can flash your connected lights and turn them red to give you an additional visual cue. You can build your own Routines from scratch, or opt into common ones we've ready-made for you. We're working with partners to provide even more innovative Routines, suggested for you based on the products you have. You’ll always be in control, and can decide to opt in or out of these actions. All the while, your sensitive information won’t be shared, so your home data remains private.

Which partners are currently on Device Access?

We have a few pilot partners that are already in the process of building their connections with us through Device Access. Stay tuned for more information once they’re ready for you.

What happens to my Works with Nest connections?

Your existing Works with Nest connections will continue to work without any changes as long as the partner continues to support it, you don’t remove them, and you don’t migrate your Nest Account to Google. If we make any changes, we’ll let you know.

What if my Works with Nest connection isn't available in Device Access or Home Routines?

Many of the same companies that are Works with Nest partners are also Works with Google Assistant partners. Check the Google Assistant What it can do page for a full list of Actions available now. Stay tuned for any additional partner connections through the Device Access program and Home Routines.


How do I learn more about becoming a Device Access developer?

If you’re a developer or a Nest customer interested in Device Access, you can find more information on our Device Access site. Check the page for the latest updates.

Will developers have access to a developer console to manage their integrations?

Yes, we will have a console for qualified commercial developers with approved integrations. For now, sign up for more information on our Device Access site.

Will developers have to pay for the commercial annual security assessment?

Yes, there is an annual cost on a case-by-case basis. One of our authorized testers determines the scope of work based on your particular use case. Once you apply, you will receive more information.

What happens if I fail the annual security assessment?

If you fail the annual security assessment, you have 30 days to fix any issues that were flagged. Once you have fixed these issues, you can schedule a reassessment.

What happens to my Works with Nest developer integrations?

Your existing Works with Nest integrations will continue to work in maintenance mode. If we make any changes, we’ll let you know.

What is the Device Access commercial review process?

There’s a qualifying review process that includes an annual security assessment and use case assessment that you have to go through before we accept your application for the Device Access API. Developers will have to pass this annual security assessment, agree to the Device Access terms of service, which includes our User Data Policy, and other additional review requirements before they are approved.

To learn more about the annual security assessment, read our blog post about the Strobe OAuth Security Assessment.

What is individual access? How is it different from commercial access?

Individual Access is for smart home enthusiasts to participate in Device Access. This allows you to directly control your own Nest devices for your private integrations up to a certain number of connections and without a formal review process. It also provides partners a chance to test their integrations before they submit for commercial access. Commercial access opens up the integration to a wider audience and requires a complete review process, including an annual security assessment.

Works with Nest had a sandbox for personal integrations. Can I do that with Device Access?

We will invite smart home developer enthusiasts to participate in our Device Access for Individuals, which lets you directly control your own Nest devices for your private integrations and automations. These smaller integrations do not require a security audit or review, and have a limited number of allowed users.

Stay tuned for more details in the future. For now, sign up for more information on our Device Access site.

How do I manage Device Access integrations?

There will be a Developer portal. If you’re interested in becoming a Device Access developer and would like more information as it becomes available, sign up on the Device Access site.
