Google Matter Early Access Program (EAP)#

The Google Matter Early Access Program is a partnership between Google and silicon providers who support Matter development. This partnership allows for faster onboarding of new devices into Matter and Thread by lowering the bar for starting with development of a new Matter-based product.

The Google Matter Early Access Program is run through the Google Developer Center.

The Matter-focused portion of the Google Developer Center is located here.

Prerequisites for Google Setup#

To run the Google Ecosystem demo you will need both Google and a Matter device. You will also need Google Nest Hub 2nd Generation and an Android phone (at least a Pixel 5 is recommended) that can run at least Android 8 (8.1, API Level 27) or newer and has Bluetooth LE capability.

Instructions for Setting Up EAP#

Once you have access, you will need to set up the Nest Hub 2nd Gen and Android phone with the Google Home app using the same Google Account that is used to access the EAP website.

If you have set up the Nest Hub 2nd Gen with the correct Google account, you will receive the OTA update to the Beta version within 24 hours. You can verify this by going to Device information > Technical information > Update Channel and the channel should read "matter-dev-current-beta-channel".
