Wattmeter - energy meter, compact power meter (Watts). Determines the amount of electricity (kilowatt / hour) consumed by a household or other appliance. The larger analogue is a stationary meter installed at the entrance of the electrical network to the room. Responsible for the total power of all energy consumers. The household appliance is used in private for an individual consumer, in workshops for the repair of household electrical appliances, electronic devices. Modern development of wattmeters - "smart" sockets with remote control via the Internet via a smartphone.
