How to use Amazon Alexa to control your Roku Smart Home devices
Alexa is the voice service from Amazon and is connected to the Alexa app, as well as other voice-activated devices like your Amazon Echo Spot, Amazon Echo Show, Amazon Fire TV, or Amazon Fire Tablet. With Alexa you can easily and quickly control your Roku® Smart Home devices with your voice.
This article helps you integrate an Alexa-enabled device with your smart home device and provides some examples of voice commands you can use to control your smart home devices.
In addition to your Roku Smart Home device, you will need the following:
A free Roku account
An Alexa-enabled device such as an Amazon Echo Show, Amazon Echo Dot, Amazon Echo Spot, Amazon Echo Plus, Amazon Fire TV, Amazon Fire Tablet, or a third-party device with Amazon Alexa
Alexa mobile app downloaded to your iOS® or Android™ device
Select Continue to Alexa App to return to the Alexa app
The Alexa app will look for your Roku devices on the Device Discovery screen. Be sure each Roku device is powered on if the Alexa app does not find it.
Select the Roku device you would like to use with Alexa, and select CONTINUE
Repeat steps 10 and 11 to link additional Roku devices you wish to use with Alexa
Notes:
If you are not able to select a Roku device you may need to tap Manage devices in the Roku Smart Home skill screen in the Alexa app to complete this step.
With your Alexa app or Alexa-enabled device, use your voice to turn your smart home device on, view a live video stream, and adjust lights settings like color, brightness, and temperature.
Control your cameras and doorbells
The live video stream from your camera and doorbell can be viewed on a display device connected to Alexa like your Amazon Echo Show or Amazon Echo Spot.
Issue a command by saying "Alexa" followed by:
Turn on your camera "Turn on living room"
View your live stream "Show my living room on bedroom" "Show my doorbell on living room"
Stop your live stream "Stop my doorbell on living room"
Before you can use your voice to turn your alarm mode off, you must change the following settings on your Monitoring hub in the Alex app.
Enable Disarm by voice
Set Voice Code to Existing security system PINs
Note: Alexa doesn't support using your PIN to change monitoring modes to Home or Away. Using your voice to change to Home or Away mode will fail if your PIN is required for mode changes.
Issue a command by saying "Alexa" followed by:
Change your monitoring mode to Home "Arm monitoring to Home" "Arm security system to Home" "Set security system to Home"
Change your monitoring mode to Away "Arm monitoring to Away" "Arm security system to Away" "Set security system to Away"
Check your monitoring mode "Is my monitoring Armed?" "Is security system armed?"
Turn your monitoring alarm mode off "Disarm" "Disarm my monitoring system"
Control your lights
Issue a command by saying "Alexa" followed by:
Turn your light on "Turn on bedroom light" "Turn on tv light strip"
Adjust brightness "Brighten living room light" "Set living room light to 50%" "Dim living room light by 75%"
Set temperature (warm, warm white, incandescent, soft white, white, daylight, daylight white, cool, cool white) "Set bedroom light to daylight" "Set bedroom light to cool white"
Set color "Set office light to red" "Set movie room light strip to purple"
Control your plugs

Turn your plug on "Turn on kitchen plug"
