(When we fit a SMETS2, we also install a ‘communication hub’ on top of the electricity meter. This creates a ‘home area network’ which means it can read your meter usage and display it on your IHD. It also sends the meter reading data to us, the supplier).
The issue is mostly affecting SMETS2 meters connecting to the network run by Arqiva, which is in the North of the UK (in the world of smart meters there’s an imaginary line near Manchester.) There are fewer issues affecting IHDs in the Central or Southern areas, which connect to a network run by Telefonica.
We, alongside other energy suppliers installing smart meters, have been waiting for a firmware update to the IHDs to fix the issue in the North.
This delay has led to the DCC (Data Communications Company, which is the Government-appointed body responsible for the rollout of SMETS2 smart meters) to ask all the IHD and meter manufacturers to work together to resolve the issue.
The latest is that the firmware update for IHDs won’t be available until late September 2019, which will resolve issues for new installs. We're waiting for more information about resolving issues with existing IHDs.
