Google Is Replacing Assistant with Gemini on Your Smart Home Devices

Google has switched out Google Assistant for Gemini, a newer AI system, across its smart home devices—speakers, displays, cameras, and doorbells. The company has also redesigned the Google Home app from the ground up. This is the biggest shift to Google's smart home platform since it first added Assistant, years ago.
The update brings more advanced AI tools to the picture. You can now describe what automation you want instead of clicking through menus, see AI-generated captions for your security camera footage, and search through video using plain language. Some of these features are free, but others require a paid Google Home Premium subscription.
What Devices Work with Gemini
The good news: you do not need to buy new hardware. Gemini works on Google smart home devices from the past ten years—speakers, displays, cameras, doorbells, and more. If you already own Google Home or Nest devices, they will get the upgrade.
Google has also made new hardware built to take advantage of Gemini. New Nest Cams and Doorbell models have better image quality and smarter alert systems. There is also a new Google Home Speaker tuned for faster voice responses. These new devices come with Gemini ready to go.
The Google Home app itself has been rebuilt. Before, Google split smart home controls between the Home app and the Nest app—you had to jump between two places. Now everything is in one app. It handles speakers, displays, cameras, doorbells, smoke and carbon monoxide detectors, smart locks, and thermostats from 2015 onward, all in the same place.
What Gemini Can Do
Your security cameras get smarter with Gemini. When you record video, Gemini automatically writes descriptions of what it sees. Then you can search for specific moments by describing them in your own words—"show me when someone walked up to the front door yesterday"—instead of fast-forwarding through hours of footage.
Creating automations becomes a conversation instead of a chore. You tell Gemini what you want to happen: "turn on the living room lights when I arrive home after sunset." Gemini figures out what trigger, condition, and action you need. You can even tell it to set up an automation based on something a camera sees—"alert me if someone enters the backyard."
There is a real shift happening here. We have seen patterns like this before, around 2016, when voice controls started replacing touchscreen menus for smart home setup. Each time the interface gets simpler, more people feel comfortable setting up automations instead of leaving their smart homes at basic "turn on and off" mode. Over time, that opens up smart home technology to people who never would have bothered to learn the old menu systems.
What Costs Extra
Google Home Premium unlocks the more powerful Gemini features. A paid subscription gives you extended voice conversations with Gemini, AI summaries of your notifications, and a daily Home Brief that tells you what happened around your house. Video search, natural language automation setup, and other advanced features also need the subscription.
This is a shift in how Google makes money from smart homes. Google traditionally relied on advertising across its products. With smart speakers and displays, advertising has always been awkward—nobody is thrilled to hear ads on their bedside speaker. Premium subscriptions let Google charge directly instead.
The New App
The redesigned Google Home app puts everything in one place. There is a new Activity Tab that shows a timeline of everything that has happened across your home—security events, automations that ran, device changes. Instead of hunting through settings and device menus, you can describe what you want to happen, and the app will do it.
If you have a Pixel Tablet docked in your home, it now shows a new screensaver panel that makes it easy to see and control your smart devices without opening the full app.
When This Rolls Out
Gemini for Home is starting in the United States only, for now. Google is calling it "Public Preview," which typically means the company expects to refine things based on what users tell them before taking it to other countries.
This geographic limitation makes sense when you think about the engineering involved. AI systems that understand natural language need to work across different languages, accents, and dialects. In the past, when Google rolled out Assistant, it got English working well first, then expanded to other languages over months or longer.
What this means for the broader smart home world is worth considering. Google is raising the bar for how smart homes should work—by letting you talk naturally instead of wrestling with menus. That lower barrier to entry could pull in people who gave up on smart home automation as too confusing. The subscription model also shows where the industry is headed: companies building smart home platforms are looking for repeating revenue, not just a one-time hardware sale. Other companies will likely copy that approach.
How successful this actually becomes depends on whether people see enough value in premium features to keep paying, month after month. For years, the smart home market assumed people would buy devices once and own them forever. Google is betting that real AI capability will change that.
