Overview
- Notifications for the second wave began going out on December 5, with some users reporting immediate setup availability.
- The program remains a gradual beta limited to US homes and requires the Google Home app version 4.1 or higher.
- Enrollment moves all eligible Nest speakers and displays to Gemini, covering models released since 2016.
- The setup flow notes English-only responses for now and asks users to set guest filters and video‑log access tied to conversational video search.
- 'Conversations across devices' lets voice‑matched users continue exchanges between rooms, still requiring the 'Hey Google' wake phrase, and users choose from roughly ten assistant voices during setup.
