The Google Home app walks you through the steps for Chromecast and Chromecast Ultra setup.
If you've already set up your Chromecast on a mobile device, you don't need to set it up again on a different mobile device if all devices are on the same Wi-Fi network.
What you need to get started
- A Chromecast device (3rd gen or older)
- A Google Account
- A display device with an HDMI input, such as a high-definition television (HDTV)
- An Android phone or tablet with Android 9.0 or later that supports a 5 GHz connection
- Access to a secure wireless network, with the password available
Important: Availability and performance of certain features, services, and applications are device and network dependent. They might not be available in all areas. Subscription(s) may be required, and additional terms, conditions and charges may apply.

- Make sure that you plug in your device before you connect it to the Google Home app. If the device has been used before, factory reset your Chromecast before you continue.
- Ensure that you have enabled location, Bluetooth, and camera permissions for the Google Home app to use these features.

Troubleshoot setup
Important: Support for Chromecast (1st gen) has ended. It no longer receives software or security updates, and Google doesn't provide technical support. Users may notice a degradation in performance.
If setup didn't work, try to:
- Reboot your Chromecast.
- Unplug your router, then plug it back in.
- Connect manually to your Chromecast's service set identifier (SSID).
- Open your phone's Settings app, tap Wi-Fi, and connect to the Chromecast SSID.
- Open the Google Home app and try to set up your device again.
- Factory reset your Chromecast.
- Contact support.
