A:Answer Samsung suggests you need to be "within 5 feet" of the remote for it to work without pressing the mic button. If you have Alexa devices elsewhere in your home, "you can also download the Alexa app on your phone or PC to pair it with SmartThings" (Samsung's smart appliance app). With this, "you can create Routines, manage devices, set up Alexa-enabled devices and Alexa Skills, and edit device settings." https://www.samsung.com/us/support/answer/ANS00087622/
