Gemini AI Upgraded to Broadcast Messages on Google Home Devices
Google has rolled out a new update that integrates Gemini AI with the Google Home Broadcast Messages feature, allowing users to send voice or text messages across their Nest smart speakers and displays. Previously reserved for Google Assistant, this functionality is now officially part of Gemini’s capabilities, reflecting Google’s ongoing shift to make Gemini its core AI platform across services.
What Is the Google Home Broadcast Feature?
A Smarter Way to Communicate Across Devices
Google Home’s Broadcast Messages feature works like a digital intercom system. It lets users send short messages, such as reminders or alerts, from one device (usually a smartphone) to all connected Nest smart speakers and displays in the home.
For example, you can send a message from your phone to the kitchen speaker saying, “Dinner is ready,” or remind the kids through the bedroom speaker, “Time to do homework.”
Until now, this was exclusively handled through Google Assistant. But with the new update, Gemini AI can now take over this role.
How Gemini AI Works With Google Home Broadcast
Voice or Text Messaging Across Rooms
According to Google’s support team, the feature is now available via the Gemini mobile app on both smartphones and tablets. Once enabled, Gemini can be prompted to broadcast a message using either text input or a voice note.
You can now say or type:
-
“Broadcast ‘I’m on my way home.’”
-
“Broadcast to the living room, ‘Turn off the TV.’”
-
“Broadcast ‘Dinner is ready’ to the kitchen.”
Gemini will then push the message to the selected Nest speaker or smart display in your home.
How to Set Up Gemini for Google Home Broadcasts
To use this feature, follow these steps:
-
Install the Gemini app on your Android or iOS device.
-
Ensure that your Google Home devices (Nest speakers/displays) are all:
-
Connected to the same Wi-Fi network.
-
Linked to the same Google account or a shared Google Family group.
-
-
Open the Gemini app and type or say a broadcast message.
-
If you haven’t enabled the Home integration, Gemini will prompt you to toggle on the extension.
-
Once activated, Gemini will immediately send your message to the selected devices.
Targeted or Whole-Home Broadcast Options
One major advantage of this update is broadcast targeting. You can now send messages to:
-
All devices in your smart home
-
A specific room (e.g., “Broadcast to the kitchen”)
-
A single device (e.g., “Broadcast to Nest Hub Max”)
This gives users greater control over who hears what—ideal for larger homes or multi-room setups.
Limitations to Be Aware Of
While powerful, the Broadcast feature with Gemini AI comes with a few notable limitations:
-
All Nest speakers and displays must be on the same Wi-Fi network.
-
Only devices logged into the same Google account or Family group are supported.
-
Third-party speakers and displays are not supported.
-
Broadcast messages are one-way only—you cannot receive replies from the devices.
-
Gemini integration must be manually enabled within the app before using the feature.
These limitations echo the structure of Google Assistant’s earlier broadcast capabilities, ensuring a consistent experience.
Why Google Is Transitioning from Assistant to Gemini
The addition of the broadcast feature is part of a broader strategy by Google to phase out Google Assistant from Android and other smart services, replacing it with the more advanced and flexible Gemini AI platform.
Gemini offers:
-
More natural language understanding
-
Tighter integration with apps and services
-
Better personalization through context awareness
-
An adaptable interface that can handle both text and voice commands
This makes Gemini a more future-ready platform for smart home use cases.
Use Cases for Gemini AI Broadcasts
This integration can streamline everyday household communication:
-
Morning announcements: “Good morning! Don’t forget your lunch.”
-
Reminders: “Homework time starts in 15 minutes.”
-
Emergency alerts: “Wi-Fi will be down for maintenance at 3 PM.”
-
Hands-free updates: While cooking or driving, you can ask Gemini to send a quick message to the family.
These scenarios highlight how AI-driven home communication is becoming more practical, seamless, and hands-free.
What This Means for Google Home Users
The update adds significant value to the Google smart home ecosystem, especially for users who rely on connected speakers and displays throughout the house.
As Gemini continues to receive more features, it’s expected that even more Google Assistant-style capabilities will be integrated into the platform, ensuring a smooth transition without losing functionality.
Smarter, More Connected Home with Gemini AI
The addition of Broadcast Messages to Gemini AI marks an important step in Google’s smart home evolution. By allowing users to communicate across their Nest devices through a more intelligent and flexible AI interface, Google is delivering on its promise of a more personalized, efficient home environment.
As the company gradually retires Google Assistant, users can expect Gemini to become the central hub of home communication, automation, and voice interaction.
