I use this, it monitors power to one device (my PC) and when it senses it turns on it automatically powers on the other plugs in line. One touch turns everything on or off(by powering down the PC)

Sorry I don't and I am not sure what they would be called in europe. I got a couple really cheap thought MassSave. Amazon US has them, just so you have a good description - here is one on Amazon https://www.amazon.com/TrickleStar-Outlet-Advanced-PowerStrip-Joules/dp/B00JPDYYSM

This one is from amazon uk - https://www.amazon.co.uk/Belkin-Energy-Saving-Smart-Power/dp/B003WK62WU

In England they are called AV power strips or cords (it is currently out of stock) - you might try that as a search term. Good luck.

Here is one with horrible reviews, but I am pointing out they may be called different things: https://www.amazon.co.uk/Energenie-ENER017-Master-Energy-Extension/dp/B00GNXY51I

BTW - if you get one from an established manufacturer, they work great.
