SmartThings works with Amazon Alexa to give you command of your smart home through voice controls. Read below for answers to some common questions about SmartThings + Amazon Alexa.
What do I need to connect Amazon Alexa with my SmartThings?
To connect with SmartThings, you need an Amazon Alexa device–like the Amazon Echo, Echo Dot, or Amazon Tap–or an Alexa Voice Service device–like the Amazon Fire tablet or Nucleus Anywhere Intercom.
Many smart devices that work with SmartThings and can be controlled with Amazon Alexa also require a SmartThings Hub. Check out our products page here to see if your smart devices require a Hub.

Can I use more than one Amazon Alexa device with SmartThings?
Yes. If you have multiple Amazon Alexa devices throughout your home and would like to use them with SmartThings, first add the Amazon Alexa devices to the same Amazon account by following the Alexa Devices instructions on the Amazon Help page.
Then, follow these steps to connect Amazon Alexa with SmartThings. You only need to perform this process once, regardless of the number of Amazon Alexa devices. Once connected, all of your Amazon Alexa devices, using the same Amazon account, can be used to control light bulbs, on/off switches, dimmer switches, thermostats, locks, and Routines associated with that single SmartThings Location. Note: For security reasons, Alexa will only support Routines with lighting, switch, and thermostat devices.
Can I control multiple SmartThings Locations with Alexa?
No, not at this time. But we are working on an update that will allow multiple Amazon Alexa devices on separate Amazon accounts to control separate SmartThings Locations.

Which SmartThings devices work with Amazon Alexa?

How do motion and contact sensors work with Alexa?
Alexa can tell you the current state of your motion and contact sensors. Alexa can also tell you when they change state with a custom message.
Here are some example phrases:
“Alexa, is my front door open?"
“Alexa, is my bedroom window open?”
Alexa can also perform actions when motion is detected or a door/window opens or closes, such as a custom Alexa notification or playing music. Click here to learn more about creating Routines in the Alexa app.

Bulbs with the ability to change colors (RGBW) can be set with any of the following options:
- Sky Blue
Bulbs with the ability to change the color temperature can be set with any of the following options:
- Warm white
- Soft white
- Cool white
How do thermostats work with Alexa?
Compatible thermostats connected to your SmartThings Hub can be controlled with Alexa.
Here are some example phrases:
“Alexa, raise kitchen thermostat by 10 degrees.”
“Alexa, 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?”
Possible responses from Alexa include:
“Setting kitchen thermostat heat to 80.” (When thermostat’s current mode is “Heat.”)
“Setting kitchen thermostat AC to 70.” (When thermostat’s current mode is “Cool.”)
“The device ‘kitchen thermostat’ is not responding.” (When thermostat’s current mode is “Off.”)
The thermostat’s mode cannot be changed via Amazon Alexa. Adjustments to mode must be made via the thermostat’s physical display, the SmartThings mobile app, or the thermostat’s native app (if applicable).
Can I use my Routines with Alexa?
Alexa will only support Scenes and 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. To learn more, check out Amazon Alexa + SmartThings Routines.
For the best Routine experience with voice, create a new Routine to use with Alexa. Here are some examples of lighting and thermostat only Routines:
Bedtime - Turn off your 2 bedroom lights and lower the thermostat to 65 degrees
Partytime - Turn off your boring recessed lights and turn on the fun color strips lights.
After creating a new lighting and thermostat Routine, set it up with Alexa (steps for existing Alexa SmartThings users or get started here).Once you’ve connected your Routine, just tell Alexa to turn them on. If you created any of the sample Routines above, simply say:
For Bedtime, “Alexa, turn on Bedtime.”
For Partytime, “Alexa, turn on Partytime.”
Alexa will respond with “Okay,” and run your new Routine with the power of your voice.
How do locks work with Alexa?
Alexa can lock and unlock your doors and also tell you the status of your locks, bringing you both instant security and peace of mind. Just give Alexa voice commands like the following examples:
“Alexa, lock the front door.”
“Alexa, is the back door locked?”

Note: For security reasons, Alexa does not support Routines with lock devices and Groups with locks added to them in Alexa will not run.
