no, it comes from the unmetered side.

But what about the smart gas meter?

They have a 10 year D-Cell to talk to the smart electricity meter, they
only send readings every 30 minutes.

They come with a charger which plugs into a mains socket. The will work
for a while until the battery discharges. Very similar in that way to a
mobile phone. To my mind their big weakness is that they have a p*ss
poor range, so as my electric meter is at the far end of the house it
will not work properly in my lounge. A frustrating waste of space.
