A Google Home Premium subscription is required to access Gemini Live on these older devices . This is consistent with Google's existing strategy: advanced Gemini for Home features — including Gemini Live and AI-powered notifications — are paywalled behind the Premium tier, which costs $10 per month or $100 per year .
The update introduced an expanded Conversational Memory that extends the assistant's recall window to 15 minutes across the entire Gemini for Home experience . This allows users to ask follow-up questions without repeating the original command or context. For example, you can say "Hey Google, turn on the kitchen lights" and then a few minutes later say "Hey Google, dim it to 50%" without Gemini forgetting the context . This addresses a long-standing frustration with smart home voice assistants that previously treated each command as a fresh, contextless request .
Beyond the headline features, the July 23 update included several other notable changes:
This update signals Google's commitment to bringing its most advanced AI assistant features to its existing hardware base, not just the latest devices. The 15-minute conversational memory is a significant quality-of-life improvement that makes Gemini feel more natural and useful for everyday smart home control. However, the paywall behind Google Home Premium may limit adoption among users who own older hardware.
Bottom line: If you own a first-gen Home Mini or Nest Hub and are willing to subscribe to Google Home Premium, the July 23 update turns your aging smart speaker into a much more capable and conversational smart home hub.
