Smart meters are the new generation of electricity meters. They are being installed in homes across India and will soon replace the traditional meters. Smart meters record your energy use in the same way as a traditional meter but then send the readings automatically to your energy supplier in real time, allowing them to prepare an accurate bill. Smart meters also show readings and can even show the calculated cost of energy on the display of the meter. A smart meter measures how much electricity you are using and very securely communicates this directly with your energy supplier in real time.
