Can’t do meter reading because ....

I used to have a smart meter with my previous supplier which is now obviously blank when plugged in. The two original meters outside appear to be active as both have a light on, but they are also blank. How then, can I take a reading ?

When you say in your first sentence you have a smart meter plugged in do you mean the In-Home Display rather than the actual smart meter?
