Charlie from Los Angeles, CA
Logitech Harmony Hub

Charlie would like to pair his old Smart TV with the Amazon Alexa. How can he do that? Leo says the the Amazon Fire TV Cube may be a good option, it works with an IR blaster. But it won't turn the TV on, since the IR blaster loses connection. Leo recommends the Logitech Harmony Hub. It'll connect to his Echo, and then will work in between the Echo and his TV.
