After my central heating boiler failed to fire up, discovered a blank display on my meter (pressing A still gave no display). After talking to OVO they thought it was almost certainly a battery failure and sent out an engineer for a fix.
Turns out he had to install a traditional meter because it was out of hours for OVO to give codes for a new smart one.
This means that we have to yet another visit to have a new smart meter installed
Why can't a battery simply be replaced under such circumstances. Should be quick and easy. It it isn't easy, why on earth not?
Why can't the unit send a warning beep to us and send a message back to base when low battery is detected?
