[Quick note - I am typing this on my tablet using tightVNC because I
still haven't found a news client on Android which suits me.]Anyway does
anyone know how gas smart meters are powered? Either they need mains
electric or have a battery which will need changing by the not-meter-
reader. Sorry about the lack of line feeds. Feature of the VNC client
probably. Cheers Dave R

I'm also intrigued how the modern PAYG card gas meters are powered too; these not only have the (back-lit) display and metering but appear to power a solenoid gas valve, that gives a satisfying 'thump' more credit is added. But no mains elec connection.
So does this poor battery have to hold the solenoid open continuously (while in credit) for years?
Some years ago a gas meter with LCD display was fitted to my
house. A year or two later it was swapped for an old fashioned
mechanical one, apparently because those responsible (I've long
lost track of who now has the contract for this aspect) for its
maintenance didn't want to have to replace batteries.

There is a button you can press on my smart gas meter to illuminate the
display, following installation I think I've pressed it twice and a
meter-reader has pressed it once, beyond that it's only used for short
distance (wireless M-Bus?) communication between the gas and electricity
meters, once every 30 minutes.
Plus communication via the mobile network, to your supplier once per
day with the stored meter readings.
Battery life is a moot point anyway - at the moment, if you change
suppliers, likely the meter will not be compatible with your new
supplier, in which case a new meter will be needed anyway.
My OVO SM's were only installed in June and as I habitually get new
quotes at the end of my supply contract, I am in the process of moving
to First Utility. Once moved over, I will re-apply for replacement SM's
- rinse and repeat.
You really couldn't make it up - £11Bn wasted. When will these
companies ever learn - loyalty and keeping those customers counts for a
big saving for them? The more customers shop around and move regularly,
the sooner the (special offers for new customers) bubble will burst.
That part I am dreading, because the reading displayed swaps so rapidly
you don't get time to read it - so it can take several attempts.
What does surprise me is that the indoor display (mine at least),
doesn't show the actual meter reading. Another issue I have found, is
that it shows the total energy cost (£ and p) since it was installed,
on the tariff I was on at that time. It is unable to show what you have
paid/still owe or in credit. I'm on credit, rather than the pre-pay
I meant to add...
You can choose the reading frequency when you apply for the SM's. Mine
store the values every 30 minutes, then sends them to the supplier once
per day at around midnight. Next day I can log into OVO's site and see
what was used, with a 30 minute resolution, going back to June .
For the current day, if the indoor unit is powered, I can see the same
consumption stored data as it happens, or see instantaneous values.
 that proved useful recently, when I decided to swap all of my most
used lamps, over to LED's - there was a large dip in the consumption
graph after the switch over, despite the darker nights closing in.

From various sources (not guaranteed accurate) there is a smart hub
associated with the smart electricity meter and this is the point of

So yes, logically, the gas meter can't operate without the electricity
Probably why they are targeting people on dual fuel first.
