Google Nest Hub (2nd gen) firmware update for Preview Program.

Starting November 21st, 2022, Nest Hubs (2nd gen) opted into the Preview Program are being updated to support Matter 1.0 in anticipation of Google's general availability (GA) of Matter. The release rollout will continue for the next few weeks.

Nest Hubs receiving the update should be on firmware version 1.56.324896 or higher after the update. To verify if your hub received the update, swipe up from the bottom of the screen, tap Settings > About device, and check the Cast firmware version.

Once your Nest Hub (2nd gen) receives the firmware update, developers will need to take the following actions for previously-commissioned Matter devices:

  1. Matter devices must be updated to firmware compatible with the v1.0-branch branch of the connectedhomeip GitHub repo. Build instructions for all vendor examples have been updated with the GitHub branch for this version.
  2. Matter devices must then be recommissioned.
