I finally realized his long-held ideas. Now I have the opportunity in the apartment, leaving the house, de-energize almost all electrical appliances. I am sure this there is almost no one.
On the jamb of the door placed a small switch.
This switch turns off all the lights, sockets, electrical, ventilation system, all appliances.
Of course, such a small switch can not turn off such a large load, so in the switchboard installed contactor Legrand CX3 with two pairs of contacts of 25A ( https://ammo1.livejournal.com/900458.html). Pairs of contacts are combined, thus contactor can drive the load with a current of up to 40A. A switch on the door includes a contactor coil.
Contactor disconnects the five machines, standing after him. Voltage after tripping served only sockets that are connected to the latter two machines. They work only refrigerator, WIFI-router, video surveillance system, computer system unit (it is always in sleep mode).
Coming out of the apartment, I now instead of light in the corridor turn off the small circuit breaker, contactor and disables everything including light in the corridor.
Thus completely solved "Iron forgotten" issue, and I can be sure that all electrical appliances in the house are turned off. Before that I often returned, realizing that he forgot to turn off the ventilation, air conditioning or anything else.
Of course, such a system, there are also disadvantages: get off the clock, which are powered by the network and have no pick-up power. I plan or replace the clock on the model with a pickup or pickup power to implement in existing hours.
I understand that I am the only one, "paranoid" and the vast majority of people do not pay note what appliances are included when they leave home, but I was so calm and it is more convenient.
