An in-home display is a small digital display that links to your smart meter and shows your home’s live energy usage data.
You should have been given this when your meter was installed. Our sign-up process uses some information obtained from this display unit as a way of verifying your right to access energy data from that smart meter.
NOTE: If your display no longer works, you will still be able to connect your smart meter by entering the MAC/GUID/EUI number printed on the side or bottom of the display.
