Thank you, I know the GAS meter uses a battery which is supposed to last 10 years, Usually the LCD screen remains blank until you press a button and then usually the LCD displays ‘Welcome to Octopus’ or something similar.
That does not happen now when I push one of the buttons, LCD screen remains blank which means GAS meter or battery could be at fault.
I think I have solved my problem, but am awaiting the morning to see if my IHD also confirms this, then will populate above reserved post places to help others.
Really annoying if my fix works, as this shows these Smart Meters are temperamental or at the very least, sensitive to mains supply fluctuation’s.
