I can't wait to be able to control my TV from one of these things. Much easier than hunting for the Roku app on my phone, since I've long lost the actual remote.
Nice. For me it seems a little ridiculous to spend $99 on an IR sensor + LED since I don't have any more home automation.
Given I gave the Echo I had away, I'm hoping the next iteration of the Echo or Google Home device has the $2 of components required to implement this functionality so that it just works out of the box.
