Help With Your Harmony
I found this website that I think would help you guys out a lot if you are wondering how to set up your Amazon Echo Harmony Skills. Hope this turns out useful for you!
For starters, you'll need an Amazon Echo or some other gadget with Amazon's Alexa voice assistant built-in. (Cheapest option is the Amazon Echo Dot -- at $50, it's a no-brainer.)
But by itself, the Echo can't control your TV, receiver, or other streaming gadgets. For that, you need a $99 Logitech Harmony Hub, a Wi-Fi equipped puck that lets Echo talk to your TV and other home entertainment products.
