How Do Smart Meters Communicate With the Grid?

Smart meters in Ireland primarily communicate with the grid in two ways:

1. Power Line Communication (PLC): This technology utilises the existing electricity cables in your home to transmit data. The smart meter sends information to a nearby communication hub, which then relays it to the ESB.
2. Mobile Network Communication: In areas where PLC is not possible, smart meters can communicate with the grid using a mobile network. This involves a small cellular module within the meter that sends data directly to the ESB.
