Google Home integration for Google TV devices was announced last September, and it's now rolling out more widely: If you haven't previously seen the feature available on your Google TV Streamer, your Google TV television, or your Chromecast with Google TV, you might find it's now available if you check again.It is, essentially, exactly what it sounds like: Devices that you've connected to the Google Home app in Android or iOS will be available through the Google TV interface, automatically linked and synced with each other via your Google account. The amount of setup you have to do is minimal, and it should just work.While you might initially wonder why you would need smart home controls on a TV, it makes sense. You can quickly dim the lights for movie night, for example, or take a look at the camera feed from the backyard without having to fish your phone out of your pocket. You'll even get an alert on screen if someone rings your smart doorbell. Look for the Google Home panel.

The feature may not have arrived for everyone yet, but you've got the best chance of seeing it if your software is up to date: From the main screen, head to the gear icon (top right), then choose All settings > System > About > System update.With that done, you can go back to the Settings panel via the gear icon, then choose Google Home from the tiles. You'll see a confirmation screen explaining the feature and allowing you to enable it, and you can then select Save to add the functionality. Depending on how your Google account is set up, you may need to confirm the connection via a prompt on another device, like your phone.Controlling your smart home devicesGoogle hasn't provided a definitive list of which of your Google Home devices will show up on Google TV, but many of them seem to be supported—including smart lights, smart cameras, and smart thermostats. The available options will vary depending on the device and how well integrated into the Google Home ecosystem it is.When it comes to Google's own Nest cameras, for example, you can select the Cameras panel to see live previews of all the cameras connected to your network. Choose any of the thumbnails shown to send the video feed full screen—taking over any other streaming apps you may have running. Use the back key on your remote to go back again.

That will lead you to a panel where you can turn all your connected lights on or off, or manage them individually. Further options depend on the type of light: With Philips Hue bulbs, for example, you can adjust the brightness of each one from your Google TV, but not the colors.To make changes to connected devices, you need to head into the Google Home app on your phone. There's no way to add or remove devices from the Google TV interface, though presumably more functionality might be on the way as the Google Home panel gets upgraded over time (and as new Nest products are launched, hopefully).You'll see there's a Favorites section in the Google Home panel on your Google TV, which matches the Favorites section in the mobile app—it's a place where you can put the smart devices you need access to most. In the Google Home app, open the Favorites tab and then tap Edit to make changes, which will be synced to your Google TV as well.
