All electric switchboards in our homes and offices should be controlled through a single remote controller just like remote-controlled TV sets, air-conditioners and other domestic appliances.

Instead of leaving our seats to turn on and off the connected switch buttons, these must be controlled by a single device connecting all lights, fans, computer, TV sets and radio sets, refrigerator and washing machine etc. altogether.
