You can connect your Alexa app to your Fire TV Stick, and then use voice commands to control your viewing through the stick. You will need to have your Fire TV Stick set up already, and both the Alexa app/speaker and the Fire stick will need to be connected to the same Wi-Fi network.
Open the Alexa app on your phone and tap the menu button in the top-left corner. From the menu, tap the Settings option and then scroll down to and select the “TV & Video” option.
You should see a couple of available services listed, including Fire TV and Xbox (this may vary). Tap the (+) button next to Fire TV. On the next screen, tap “Link Your Alexa Device”.
Hopefully, after a second or two, you should see the name of your Fire TV Stick listed. Select it and then tap Continue.
Next you will need to choose the Alexa device you want to link it to, and you should see your Echo speaker listed. Tap any and all devices you want to link (you can link more than one) then then tap the “Link Devices” button.
If successful, you should see a list of your now linked devices which includes your Fire TV Stick.
There are lots of commands you can now use to control and watch TV and Movies through your Fire TV Stick. If your Alexa device has a screen, such as the Echo Show, all commands should be finished with “on Fire TV”, e.g. “Alexa, watch <movie name> on Fire TV”.
