I had a few hours, so as an experiment, I decided to integrate my Harmony Home Hub with Alexa allowing me to control my TV, Netflix etc through the Echo. I have published all the code with directions at

Hi Jon, Thank you for sharing your source code with the Amazon developer community! We appreciate your time and effort, and hope it will be beneficial for anyone interested in home automation. Kind regards, Levon
Actually Amazon Echo has added a new function "Trigger" into IFTTT. This allows statements to be created "Alexa, trigger my tv off" where the statement "tv off" is a phrase that Harmony activity is associated to perform all the hardware functions in powering down the TV. Any of the Harmony activities can now be "triggered" using this. Well done!
