Some internet radios will automatically restart after a power failure and reconnect. The Roku does this.
As for remotely controlling the carrier, I’m not sure how to do that. I just unplug the box when I want to power it down. If you were really remote and, say, powering everything with batteries and/or solar power, that could be a problem. I would imagine you could rig something up with an infrared remote if you really wanted to. Or, failing that, some sort of wire hanging down from the box with an off/on switch.
