“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 Scenes with Alexa?

Alexa will only support Scenes that contain only 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. 

For the best Scenes experience with voice, create a new Scene to use with Alexa. Here are some examples of lighting and thermostat only Scenes:

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 Scene, set it up by having Alexa discover device. Once you’ve connected your Scenes, just tell Alexa to turn them on. If you created any of the sample Scenes above, simply say:

For Bedtime, “Alexa, turn on Bedtime.”

For Partytime, “Alexa, turn on Partytime.”

Alexa will respond with “Okay,” and run your new Scene 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?”
