How to connect Amazon Alexa with SmartThings

SmartThings can connect with Amazon Alexa devices as a Smart Home Skill to give you command of your home through voice controls.

SmartThings works with Amazon Echo, Echo Dot, and Amazon Tap. Alexa can be used to control light bulbs, on/off switches, dimmer switches, thermostats, locks, and Routines configured with SmartThings.

Note: For security reasons, Alexa cannot unlock locks and will only support Routines with lighting, switch, and thermostat devices. Learn more about Routines and Alexa here.

  2. Set up your Amazon Alexa device and download the Amazon Alexa mobile app

 

Connect Amazon Alexa with SmartThings

In the Amazon Alexa app:

  1. Tap the menu (three horizontal lines in the top left)
  2. Tap Smart Home
  3. Scroll to Your Smart Home Skills
  4. Tap Get More Smart Home Skills
  5. Enter “SmartThings” in the search field
  6. Tap Enable for SmartThings
  7. Enter your SmartThings email and password
  8. Tap Log in
  9. Choose your SmartThings Location in the From: menu
  10. Tap Authorize
    Note: You can limit the devices Alexa accesses later in the SmartThings app
  11. Once authorized, the following message appears: “Alexa has been successfully linked with SmartThings.”
  12. Tap 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 Routines. Now your Amazon Alexa device needs to “discover” or locate the devices and Routines.

 

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. Tap Discover Devices
  3. Wait for device discovery to complete

Note: Discover Devices will also discover your Routines.

 

If Alexa does not begin discovering devices:

  1. In the Amazon Alexa app, tap the menu
  2. Tap Smart Home
  3. Scroll to Your Devices
  4. Tap Discover devices
  5. Wait for device discovery to complete

 

A progress bar appears in the Amazon Alexa app while Alexa looks for SmartThings devices and Routines you have authorized access to. This can take up to 20 seconds.

When discovery completes, discovered devices and Routines will list under Your Devices in the Smart Home section of the Amazon Alexa app.

 

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, 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, lock my front door.”

“Alexa, is the back door locked?”

“Alexa, turn on Good Morning.” (Routines can be executed just like turning on a switch.)

“Alexa, turn on Good Night.”

Note: At this time, Alexa will only support Routines that contain only thermostats (US only) and lighting devices. Your existing Routines 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 access

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 Routines. However, you can edit the devices Alexa can access with these steps:

In the SmartThings app:

  1. Tap Automations
  2. Tap SmartApps
  3. Tap Amazon Alexa
  4. You will see the toggle switch for Allow Alexa to access all devices and Routines–toggle the switch to the OFF state
  5. Tap Switches, Thermostats, or Locks
  6. Tap the checkbox for each device you want Alexa 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 Next
  10. Say: “Alexa, discover devices.” (After device access is removed, Alexa will automatically refresh the accessible devices list within two hours, but prompting the discovery will refresh the list immediately)
  11. Wait for Alexa to confirm discovery is complete (up to 20 seconds)
  12. Tap Done

 

Add new devices or Routines to Amazon Alexa

After connecting your Amazon Alexa device, if you add a new supported device or Routine to your existing SmartThings setup, it’s simple to give Alexa access.

 

By default, Alexa receives blanket permissions to access all of your SmartThings devices and Routines when you authorized your SmartThings account in the Amazon Alexa app, which extends permission to any newly added devices and Routines, as well. Alexa searches for new devices once every two hours. If you did not edit the devices that Alexa can access at a later time in the SmartThings app, Alexa will automatically discover and be able to control new devices and Routines within two hours with no action on your part. However, if you don’t want to wait two hours, simply say, “Alexa, discover new devices,” and wait (up to 20 seconds) for discovery to complete. You’ll then be able to control your new devices through Alexa immediately.

 

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

Note: You can only choose to grant Alexa access to all Routines or no Routines. You cannot choose individual Routines as you can choose individual devices. If you granted access for Routines, simply say, “Alexa, discover new devices,” or wait up to two hours for Alexa to automatically discover your new Routines.

 

In the SmartThings app:

  1. Tap Automations
  2. Tap SmartApps
  3. Tap Amazon Alexa
  4. You will see the devices Amazon Alexa currently has access to
  5. Tap Switches, Thermostats, or Locks
  6. Tap the checkbox for each new device Amazon Alexa 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 Next
  10. Say: “Alexa, discover new devices.” (After new devices receive checks in their checkboxes, Alexa can automatically discover your new devices within two hours, but prompting the discovery will allow Alexa to control them immediately)
  11. Wait for Alexa to confirm discovery is complete (up to 20 seconds)
  12. Tap Done
