A:Answer I don't see a reason why it wouldn't. What you will need is a Harmony Elite or Harmony Hub standalone. Alexa will connect to the Harmony through a Harmony skill. You will need to set up the Harmony to recognize your projector... this is REALLY easy. Currently I run my tv, receiver, xbox1, ps4 and lights. By telling alexa to "turn on tv" my tv comes on, receiver turns on, and lights if it is sundown.. (my option, u can do this if u want)
Ur key is going to be the Harmony Hub. Once that is set up alexa will connect really easy. And ur done.
