Hi, is there a way to make the Mi box to behave like a "normal" Chromecast? In the way that its always available to cast to. And when you do the tv reacts to that and starts by itself. Not only do I want this because this is easier. But also because I want to be able to incorporate it in different scenes in smart home automation. And if the case is that the Mi box is unable to to this, does the Google TV work in that way? Thanks in advance!
I'm not familiar with the Mi box, but that sounds like an HDMI CEC thing. Have you checked the settings for your TV's HDMI ports?
