How to connect Amazon Alexa with SmartThings

SmartThings works with the Amazon Alexa app and certified Amazon Alexa devices. Alexa can be used to control light bulbs, on/off switches, dimmer switches, thermostats, locks, and Scenes configured with SmartThings. Alexa can also check the status of motion and contact sensors. 

Note: For security reasons, Alexa will only support Scenes with lighting, switch, and thermostat devices.

Connect Amazon Alexa with SmartThings

SmartThings and Alexa can be linked through either the SmartThings app or the Amazon Alexa app. You can find the steps for each below.  

  • SmartThings app
  • Amazon Alexa app

To connect Alexa with the SmartThings app:

  1. From the Home screen, touch the Plus (+) icon and select Voice Assistant
  2. Touch Amazon Alexa
      You will automatically be directed to the Amazon App 
  3. Touch Enable to use for SmartThings
  4. Touch Authorize
      Once authorized, the following message appears: “Alexa has been successfully linked with SmartThings.”
  5. Touch x to close the window and begin device discovery

To connect SmartThings with the Amazon Alexa app:

  1. Touch the Menu (Menu icon) in the top left
  2. Choose Skills & Games
  3. Search for and select the SmartThings Skill
  4. Touch Enable to use
  5. Enter the Email/Password for the Samsung account and select Sign-In 
  6. Touch Authorize to complete setup
      Once authorized, the following message appears: “Alexa has been successfully linked with SmartThings.”
  7. Touch x to close the window and begin device discovery

 

Discover devices with Amazon Alexa

In the previous steps, you gave Amazon Alexa permission to access your SmartThings devices and Scenes. Now your Amazon Alexa device needs to “discover” or locate the devices and Scenes.

In the Amazon Alexa app:

  1. After closing the success message in the previous steps, the Alexa app automatically directs you to discover devices
  2. Touch Discover Devices
  3. Wait for device discovery to complete
    Note: Discover Devices will also discover your Scenes

If Alexa does not begin discovering devices:

  1. In the Amazon Alexa app, touch the Smart Home menu (house icon in the bottom right)
  2. Touch the plus icon
  3. Touch Add Device
  4. Select Hub
  5. Select SmartThings
  6. Touch Discover Devices
  7. Wait for device discovery to complete

A progress bar appears in the Amazon Alexa app while Alexa looks for SmartThings devices and Scenes you have authorized access to. This can take up to 45 seconds. When discovery completes, discovered devices will list under Devices and Scenes in the Smart Home section of the Amazon Alexa app.

You can use the Alexa app to automate devices and Scenes after discovery by touching on the name or icon of the device or Scene. Scenes will be displayed under the Scenes tab of the Smart Home section in the Amazon Alexa app.

 

Give voice commands to Amazon Alexa 

Now you’re done with setup and ready to use Alexa’s hands-free voice control for your SmartThings devices.

Try out these phrases:

“Alexa, turn on/off the bedroom light.”

“Alexa, dim/brighten the kitchen light.”

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

“Alexa, turn the patio lights to blue.”

“Alexa, is the bedroom window open?”

“Alexa, turn the desk light to reading.”

“Alexa, set the kitchen light to soft white.” (For additional light color and temperature options, go here.)

“Alexa, raise/lower kitchen thermostat by 10 degrees.”

“Alexa, set kitchen thermostat to 70 degrees.”

“Alexa, what is the temperature in my home?”

“Alexa, what is my thermostat set to?”

“Alexa, is the front door open?”

“Alexa, lock my front door.”

“Alexa, is the back door locked?”

“Alexa, turn on theater mode.” (Scenes can be executed just like turning on a switch.)

Note: At this time, Alexa will only support Scenes that contain thermostats (US only) or lighting devices. Your existing Scenes may not work if they have an unsupported device. Unsupported devices include: door locks, garage door openers, security systems, security devices, cameras, and smart cooking appliances. 

 

Edit the devices Alexa can control

When you authorize your SmartThings account in the Amazon Alexa app, by default, Alexa receives blanket permissions to access all of your SmartThings devices and Scenes. However, you can edit the devices Alexa can control with the Amazon App.

In the Amazon app:

  1. Touch the House Icon in the bottom right 
  2. Select All Devices or choose the group your device belongs to
  3. Touch the device you would like to edit
  4. Touch the Settings Icon in the top right
  5. Touch the Slider next to "Enabled" to disable control of the device
      This will not affect control of the device from SmartThings
