The home display itself gives monthly data. Having to read the gas meter until the recent remote fix of it all that was necessary was to push a button to activate the display and I would not say it was buried in a sub menu. The one thing that does puzzle me is how does the gas meter transmit data, and show its display when asked? Presumably there is a battery which at some point is going to need replacing and does that trigger an alert before hand (please not like a smoke alarm at 3am) as I doubt you get free gas whist the battery is dead.
