Welcome to the community.
Are you asking about your actual meters, or, the in home display.
If the latter, these often fail to work correctly after a switch.
There is work going on to make your meters work as they should, but it is a way off yet.
If the actual meter and you have tried waking it up by pressing buttons, you will need to contact the team via Wattbot, type message the team before asking your question. Replies are not instant usually within 24 hours.
