Google Replaces Assistant with Gemini in Smart Homes

Google has begun an early-access rollout of Gemini for Home in the U.S., replacing Google Assistant on compatible smart speakers, displays, cameras and doorbells and providing a more context-aware, multi-step conversational experience powered by its Gemini LLM. Users invoke routine tasks with “Hey Google,” while “Hey Google, let’s chat” launches Gemini Live; Google has published example prompts (including 100 suggestions) and new realistic voices to showcase capabilities. The most advanced features — Gemini Live and voice search through camera history — require a Google Home Premium subscription (about $10/month or $100/year), and only a subset of devices support Gemini Live today. To join early access users must enable “Add me to their groups” in Google Groups and request access via the Google Home app; once switched, Gemini replaces Google Assistant on compatible devices and cannot be reverted. Google is also shipping a new $99 speaker designed for Gemini due spring 2026, and says the update will reach more devices and additional countries next year; the rollout is limited to eligible devices, so users should check compatibility lists before requesting access.
