I couldn’t find my remote going to bed. So I asked Google to shut off the TV and it did. WTF? The Chromecast is just plugged into the HDMI and the TV is 5 years old. No way that functionality should link up.
This is a feature of HDMI-CEC (Consumer Electronics Control) which has been a standard for about 17 years. Not every device uses this feature but it certainly is something you might expect a 5 year old television to be able to do.
