The Google Home app walks you through the steps for Chromecast and Chromecast Ultra setup.

- The latest version of the Google Home app
- A Google Account
- A display device with an HDMI input, such as a high-definition television (HDTV)
- iPhone or iPad with iOS 16.0 or later
- Access to a secure wireless network, with the password available
