Starting September 29, 2023, all Works with Nest connections will stop working. You can continue to automate your home by creating Routines in the Google Home app’s automation tab or the script editor, available 2023 to Public Preview.
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 require a Nest Account to be set up prior to August 19, 2019. New Works with Nest connections cannot be set up after August 31, 2019, but your existing connections will continue to work with your Nest Account until September 29, 2023.
Works with Google Home (WWGH), formerly Works with Hey Google, enables the Google Assistant to control all your connected devices. You can use the Google Assistant to create Assistant Routines in the Home or Assistant apps. We’ve announced two new aspects of WWGH specifically for the products in your home: Device Access and Home Routines.
Moving to a Google Account will give you the benefit of a single account, seamless experiences, and the ability to align homes and home members across the Nest and Google Home apps.
