How to connect Google Assistant with SmartThings

The Google Assistant is a voice-activated assistant available on the Google Home speaker. Ask it questions. Tell it to do things. It’s your own Google–always ready to help. Just start by saying, “Ok Google” to enjoy music, get answers straight from Google, manage your everyday tasks, and easily control smart devices around your home with SmartThings.

With voice control through the Google Assistant, you can control lighting and plugs and Routines without leaving your couch!

Note: For security reasons, Google Assistant will only support Routines that trigger lighting actions, door locking, arming Smart Home Monitor, and mode changes. Your existing Routines may not work if they have an unsupported action or device, including but not limited to: unlocking locks, disarming Smart Home Monitor, and opening garage doors.

Get started

First, download the SmartThings mobile app for Android or iOS and create an account.

The Google Assistant requires a Google Home speaker and the companion Google Home app. Download the Google Home mobile app for Android or iOS and set up your Google Home device before connecting with SmartThings.

 

Connect Google Assistant with SmartThings

  1. Open the Google Home app and tap the menu
  2. Verify that the Google account that is listed is the one you used to set up Google Home. To switch accounts, click the dropdown arrow to the right of the account name
  3. Tap Home control
  4. Under Devices, tap the plus icon in the bottom right
  5. Tap SmartThings / Samsung Connect
  6. Enter your SmartThings account email address and tap Next
  7. Enter your password and tap Sign in
  8. Choose your SmartThings Location in the From: menu
  9. Tap Authorize
    • All devices and Routines from this Location will be authorized
  10. You can assign your devices to rooms (see steps below), or tap Done>Got it

 

Assign your devices to rooms

By assigning your SmartThings devices to a room with Google Home Control, you can control multiple lights as a group. First, add rooms in Google Home Control and then assign devices to your rooms.

Note: Rooms set up in Google Home Control are completely separate from the Rooms in the SmartThings app. The Google Assistant will not recognise SmartThings Rooms, and you will need to assign your devices to rooms within Google Home Control in order to control them by room with the Google Assistant. Also, Routines cannot be activated through a command for a Room, so we do not recommend adding Routines to Rooms.

  1. Open the Google Home app and tap the menu
  2. Tap Home control
  3. Tap Rooms
  4. Tap the plus icon in the bottom right
  5. Select a room to add
    To add a room that’s not listed, tap Custom Room at the bottom
  6. Tap Done
  7. Next, tap the Devices tab
  8. Select a device you want to assign to a room
  9. Tap Room
  10. Select the room you would like to assign the device to
  11. Tap the back arrow and repeat the process to add more rooms and assign more devices to your rooms

This completes the setup and you’re ready to control your SmartThings devices with your voice through the Google Assistant.

 

Give voice commands to Google Assistant

Here are some sample phrases for lighting and switch devices. For the Google Home speaker, you can use “Ok Google” and “Hey Google” interchangeably.

“Ok Google, turn on/off all lights.”

“Ok Google, turn on/off all switches.”

“Ok Google, turn on/off everything in the kitchen.”

“Ok Google, dim/brighten the lights in the living room.” (This will adjust the brightness by 20%)

“Ok Google, set the bedroom light to 10%.” (Brightness can be modified on a scale of 0-100%.)

“Ok Google, dim/brighten the bathroom light by 50%.”

“Ok Google, turn lights in the game room green.”

“Ok Google, turn on/off everything.”

“Ok Google, is the patio light on?”

“Ok Google, is the children’s light off?”

 

Note: The Google Assistant recognises “lights,” “switches,” and “outlets” as different kinds of devices. E.g., if you say, “Ok Google, turn on the lights,” it will turn on smart light bulbs but may not turn on smart switches that are connected to lamps or other lighting fixtures. To control those switches, add the word “light” to the name or nickname of the device.

 

Here are some sample phrases for Routines:

“Ok Google, run Good Morning.”

“Ok Google, activate Movie Time.”

 

Note: For security reasons, Google Assistant will only support Routines that trigger lighting actions, door locking, arming Smart Home Monitor, and mode changes. Your existing Routines may not work if they have an unsupported action or device, including but not limited to: unlocking locks, disarming Smart Home Monitor, and opening garage doors.

 

Edit the devices Google Assistant can access

When you authorize your SmartThings account for Google Assistant, by default, Google Assistant receives blanket permissions to access all of your SmartThings devices and Routines. However, you can edit the devices Google Assistant can access with these steps:

In the SmartThings app:

  1. Tap Automations
  2. Tap SmartApps
  3. Tap Google
  4. You will see the toggle switch for Allow Google Assistant to access all devices and Routines–toggle the switch to the OFF state
  5. Tap Switches
  6. Tap the checkbox for each device you want Google Assistant to access
  7. Tap Done
  8. You can also toggle the switch for Routines to the ON state
    Note: You can only choose all or no Routines. You cannot select individual Routines
  9. Tap Done

 

Add new SmartThings devices to the Google Assistant

By default, Google Assistant receives blanket permissions to access all of your SmartThings devices and Routines when you authorized your SmartThings account during setup, which extends permission to any newly added devices and Routines, as well. If you add new devices or Routines to SmartThings after you’ve connected the Google Assistant, the new device or Routine will be added automatically and will be ready for voice control through Google Assistant right away!

 

If you edited the Google SmartApp in the SmartThings app to remove blanket permissions and limit Google Assistant’s access to only certain devices you’ve chosen, use the following steps to add new devices to Google Assistant.

Note: You can only choose to grant Google Assistant access to all Routines or no Routines.

 

In the SmartThings app:

  1. Tap Automations
  2. Tap SmartApps
  3. Tap Google
  4. You will see the devices Google Assistant currently has access to
  5. Tap Switches
  6. Tap the checkbox for each new device Google Assistant needs access to
  7. Tap Done
  8. You can also toggle the switch for Routines to the ON or OFF state, if needed
  9. Tap Done

Disconnect SmartThings from Google Assistant

To properly disconnect SmartThings from the Google Assistant, you need to both unlink your SmartThings account from the Google Home app and delete the Google SmartApp in the SmartThings app.

Note: If only one of the above is completed, your Google Home device will no longer accept voice commands for SmartThings devices and cannot be reconnected until completely disconnected.

Also, if you have shared your SmartThings Location with any other users and they have connected their Google Assistant with your Location, the Google Assistant will be unlinked for your Google account only and remain available to them. To completely remove SmartThings from the Google Assistant, all shared users must also unlink SmartThings from their Google account.

  1. Open the Google Home app and tap the menu
  2. Tap Home control
  3. Tap the three vertical dots in the top right
  4. Tap Manage accounts
  5. Tap SmartThings / Samsung Connect
  6. Tap Unlink account
  7. Tap Unlink to confirm

 

Next, in the SmartThings app:

  1. Tap Automation
  2. Tap SmartApps
  3. Tap Google
  4. Select Tap to uninstall
  5. Tap Uninstall
  6. Confirm removal (this cannot be undone)
