Smart Meters are used to measure and keep track of your electrical energy use. They measure the ‘moment-to-moment’ usage of electricity so that you can monitor your energy consumption more accurately and be more economical in terms of your consumption. These Smart Meters communicate with each other through what is known as ‘mesh networking,’ whereby they communicate directly with other Smart Meters and relay the information back to the power company. This means the power company does not have to send people to your home to check your consumption as it can all be carried out remotely.
