I really like how the Chromecast can turn my TV to the correct source and turn it on when I start casting. But is there a way to tell it to turn the TV off when I'm done with it. For example I'm using my ipad to start a movie on Netflix and cast it to the Chromecast. Everything works good. But I left the TV remote next to the TV. Is there a way to turn the TV off from the ipad or a computer with the Chromecast that way I can literally leave my TV remote in a drawer and never have to tough it?
