A smart plug is a power plug and socket (also known as a wall plug, outlet, or electrical connector) which can be fitted between power cords and sockets to function as a remote-controlled power switch. As such, smart plugs can be used to make "dumb" electrical equipment smart, and thereby enable such devices for home automation or building automation purposes.<ref>Smart plugs: what they do and how to best use them in your home | Asurion</ref><ref>What Is a Smart Plug?

Many smart plugs have a built-in ammeter so that electric energy consumption (measured in kilowatt-hours) of the connected equipment can be monitored.<ref>"Benefits of smart plugs".
