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

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. Devices from this Location are selected automatically
    Optional: Deselect any individual devices that you don’t want Google Assistant to access. (We recommend keeping lighting devices only)
  10. Tap Authorize
  11. 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.

  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.

 

Add new SmartThings devices to the Google Assistant

If you add new devices to SmartThings after you’ve connected the Google Assistant, you can grant the Google Assistant access to those new devices with these steps.

  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 Check for new devices
  7. Choose your SmartThings Location in the From: menu
  8. Select the new devices that appear in the list
  9. Tap Authorize
  10. New devices will be listed at the bottom of the screen. You can assign your devices to rooms (see steps below), or tap Done

The Google Assistant can now control your new devices!

 

Connect additional Google devices

Note: While you can use multiple Google Home speakers, you can only control one SmartThings Location with the Google Assistant.

 

I already have a Google Home device connected to SmartThings, how do I add another one?

To connect additional Google Home devices to your SmartThings system, simply perform the initial setup for any additional Google Home devices in the native Google Home app and be sure to use the same Google Account used to set up your first Google Home. Your new Google Home will be instantly ready to control lights and plugs associated with that single SmartThings Location!

 

Disconnect SmartThings from Google Assistant

Note: To properly disconnect SmartThings from the Google Assistant, you should perform this action from either the Google Home app or from the Google Assistant. Uninstalling the Google Assistant from the SmartThings app will still remove the connection between the Google Assistant and SmartThings, and your Google device will no longer accept voice commands for SmartThings devices.

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
