You can do this with a door sensor modification. Buy a small 220 volt (or more precisely what your mains voltage is) relay and plug it into the network that goes offline. You need to open the door sensor and bring out two wires that you will connect to the 220V sockets. relay. If you cannot do this manipulation, look for an electrician. In this case, you will simulate the opening and closing of the door when the power is turned off and on. Once you have this option you will be able to make your scenes as well.
