Smart outlets should have a specific purpose for their use. I use them, for example, to control my Christmas lights. That way I can turn on and off lights on a schedule, and I put my blow-up decorations on a separate switch, so on windy days I can leave them powered off.
I don't have any of my AV gear on a controlled power outlet at all. There's just no reason for it. I don't want to hard power off any of my devices at any time and a lot of gear doesn't handle being unplugged and plugged back in very well. It's very hard on power supplies to pull power from them. Especially if they were on. Better to leave them plugged in all the time.
