How to connect Google Assistant with SmartThings

The Google Assistant is a voice-activated assistant available on the Google Home speaker and all Google Android devices. 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, plugs, thermostats, and Scenes without leaving your couch!

Google Assistant can also tell you the current state of door/window sensors and temperature sensors, so you can make sure your home is safe and secure.

Note: For security reasons, Google Assistant will only support Scenes that trigger lighting actions, door locking, arming SmartThings Home Monitor, and mode changes. Your existing Scenes may not work if they have an unsupported action or device, including but not limited to: thermostats, unlocking locks, disarming SmartThings 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 either a Google Home speaker, an Android 6.0+ mobile phone, or an Android Wear 2.0+ device to connect with SmartThings. Here's how you can prepare your specific device to connect with SmartThings:

  • Google Home: Download the Google Home mobile app for Android or iOS and set up your Google Home device before connecting with SmartThings
  • Android Mobile 6.0+: The Google Assistant is available on Android 6.0+ mobile phones. Simply ensure you have Google Assistant enabled by long pressing the home button, as your Android phone will connect directly to SmartThings through the Google Assistant.
  • Android Wear 2.0+: Download the Android Wear app for Android or iOS and connect your Android Wear 2.0+ device, and be sure to copy or log in to your Gmail account on the watch. You may also need to update the Google app within the Google Play store on your watch.

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 recognize 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, Scenes cannot be activated through a command for a Room, so we do not recommend adding Scenes to Rooms.

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 recognizes “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 thermostats:

“Ok Google, set the living room thermostat to 70.”

“Ok Google, turn the thermostat up/down 5 degrees.”

“Ok Google, make it warmer/cooler.” (This will adjust the temperature by 2 degrees.)

“Ok Google, turn on the heat/cooling.” (This will change the mode and/or turn the thermostat on)

“Ok Google, turn thermostat to heat-cool mode.”

“Ok Google, turn off the thermostat.”

“Ok Google, what’s the temperature inside?”

“Ok Google, what’s the thermostat set to?”

 

Here are some sample phrases for Scenes:

“Ok Google, run Good Morning.”

“Ok Google, activate Movie Time.”

 

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

 

You can also ask Google Assistant for the current state of contact and temperature sensors:

“Ok Google, is my front door open?”

“Ok Google, is my bedroom window open?”

"Ok Google, what temperature is the kitchen motion sensor?"

"Ok Google, what is the temperature of the back door?"

 

Add new SmartThings devices to the Google Assistant

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