I have a multiplug with "slave" and "master sockets". The slave sockets turn off if the appliance plugged into the master stops drawing power. I can turn off my PC remotely (I have a smart plug plugged into it) and it turns off my monitors and my desk lamp etc. It's on a timetable and switches on and off automatically as I leave or come back home.
This kind of set up gives lots of options.
