The Google Home App, Made Simple
Last verified: August 2026
If you have a Google Nest speaker, a Nest thermostat, a Nest doorbell, or a Google Nest Hub screen, there is one app that ties them all together. It is called Google Home. This guide walks you through it slowly, one screen at a time.
Getting the App and Signing In
The Google Home app is free. The trick is signing in with the right account so all your devices land in one place.
- On an iPhone or iPad, open the App Store and search Google Home. Look for the little colored house icon.
- On an Android phone, open the Play Store and search Google Home. It may already be installed.
- Tap Get or Install, then open it when it finishes.
Setting Up Your Home
In Google Home, a 'home' is just a labeled space that holds all your rooms and devices. Most people only ever need one.
The first time you open the app, it usually offers to create a home for you. If it did, you are already done with this step. If not, here is how.
- Tap the plus (+) in the top left corner.
- Tap Create home.
- Give it a plain name like Home or the Smith House. This is just for you.
- You can add your address if you want weather and travel times, but you can skip that too.
Adding and Naming Rooms
Rooms are what make voice commands work. When Google knows a light lives in the kitchen, 'Hey Google, turn on the kitchen lights' just works.
- On the home screen, tap Settings (the gear), then look for Rooms and devices, or tap and hold a device tile to assign its room.
- Choose from the ready-made room names like Kitchen, Living Room, Bedroom, or Bathroom.
- If your room is not listed, pick Add custom room and type a name like Sunroom or Bill's Office.
Adding a New Device
This is the heart of the app. Almost everything you add starts the same way, from the plus button.
The app walks you through connecting the device to your Wi-Fi. Have your Wi-Fi password handy before you start -- it saves a lot of hunting around.
- Plug in or power up the new device and set it near your phone.
- In the app, tap the plus (+) in the top left.
- Tap Set up device.
- Choose New device for anything from Google or Nest, or Works with Google Home for other brands.
- Pick the home it belongs to, then follow the on-screen steps.
- When asked, assign it to a room and give it a clear name.
Adding Devices From Other Brands
Google Home does not only work with Google gadgets. Many lights, plugs, and switches from other companies work too. There are two common ways to connect them.
- Tap the plus (+), then Set up device, then Works with Google Home.
- Search for the brand, like Philips Hue, Wyze, or Kasa.
- Sign in to that brand's account when asked. This links the two apps.
- Your devices from that brand then appear in Google Home.
Favorites -- Your One-Tap Controls
You do not want to hunt through menus every time you turn off a lamp. Favorites put your most-used controls right on the first screen.
- Open the app to the Favorites tab at the bottom.
- Tap Edit or the pencil, or tap and hold any device tile.
- Turn on the star for the controls you use every day.
- Drag the ones you use most to the top.
Turning Things On and Off by Tap
Voice is handy, but sometimes you just want to tap a button. The app makes that simple once you know where to look.
- Tap a device tile once to turn it on or off.
- Tap and hold, or tap the tile then look for a slider, to dim a light or change temperature.
- For color bulbs, look for the color dots to change the shade.
- Tap the room name to control everything in that room at once.
Controlling Everything by Voice
Once your devices are named and in rooms, your voice is the fastest remote in the house. Just start with 'Hey Google' or 'OK Google.'
- Hey Google, turn on the kitchen lights.
- Hey Google, dim the living room lights to fifty percent.
- Hey Google, set the thermostat to seventy.
- Hey Google, turn off all the lights.
- Hey Google, is the garage door closed?
Your Nest Thermostat in the App
If you have a Nest thermostat, the Google Home app is where you check it, change it, and set schedules without walking to the wall.
- Tap the thermostat tile to see the current temperature.
- Drag the dial or use the plus and minus to change the target.
- Tap the mode button to switch between Heat, Cool, and Off.
- Tap the Eco leaf to drop to an energy-saving temperature quickly.
Nest Cameras and Doorbells
Your Nest camera or doorbell lives in the Google Home app too. Here is how to watch, review, and manage it.
- Tap the camera tile to see the live view.
- Turn your phone sideways for a bigger picture.
- Scroll the timeline under the video to look back at events.
- Tap an event to watch a clip of what set it off.
Nest Speakers and Displays
Your Nest Mini, Nest Audio, or Nest Hub screen is set up and adjusted in this same app. A few settings make a big difference in daily use.
- Tap the speaker tile, then the gear, to reach its settings.
- Set the default music service so 'play some music' uses the one you like.
- Turn on or off the microphone with the physical switch on the device.
- On a Nest Hub, set your photos to show when it is idle.
Simple Automations (Routines)
An Automation is a set of actions that happen together with one trigger -- a time, a word, or the sun going down. They sound fancy but they are easy to build.
- Tap Automations at the bottom, then the plus (+) to create one.
- Choose a starter, like when you say 'Good morning.'
- Add actions: turn on the kitchen lights, read the weather, start the coffee plug.
- Give it a name and tap Save.
- Test it by saying 'Hey Google, good morning.'
Sharing Your Home With Family
You can invite a spouse, a child, or a helper so they can control the devices too. Everyone uses their own Google account, so you do not have to share your password.
- Tap Settings (the gear), then Household or Home members.
- Tap Invite home member or Add person.
- Type their Google email address and send the invite.
- They tap Accept in their own Google Home app.
Getting the Right Notifications
Notifications are the little alerts your phone shows -- a doorbell ring, a camera event, a low battery. Too many and you ignore them; too few and you miss what matters.
- Tap Settings (the gear), then Notifications.
- Turn on the alerts you care about, like doorbell presses and person detection.
- Turn off chatty ones you do not need, like every passing car.
- For a camera, open its settings to set Activity zones so it only watches the areas that matter.
A Tour of the Home Screen
The app moves things around from time to time, but the main pieces stay the same. Here is what you are looking at.
- Favorites -- your starred, everyday controls.
- Devices -- everything you own, grouped by room.
- Automations -- your routines and schedules.
- Activity or a similar tab -- recent events and history.
Renaming, Moving, and Removing Devices
Homes change. You move a lamp, replace a speaker, or finally give that plug a sensible name. Here is how to keep things tidy.
- Tap the device tile, then the gear for its settings.
- Tap the name to change it. Use the words you actually say.
- Tap Room to move it to a different room.
Wi-Fi -- The Thing That Ties It Together
Almost every smart device leans on your home Wi-Fi. When several things act up at once, Wi-Fi is usually the reason.
- Give your devices a strong signal. Ones far from the router are the first to drop off.
- If your router asks, keep the same network name after any changes, so devices reconnect on their own.
- Restart your router every few months. Unplug it, wait thirty seconds, plug it back in.
When Something Will Not Respond
Before you decide anything is broken, run through this calm checklist. Nine times out of ten, one of these brings it back.
- Check the device has power and is plugged in.
- In the app, pull down to refresh, and see if the tile says Offline.
- Make sure your phone is on the internet and try again.
- Restart the stubborn device -- unplug it, wait, plug it back in.
- Restart your Wi-Fi router if several things are offline.
- As a last resort, remove the device in the app and add it again.
