Hi @jimmey, welcome to neighbourhood. While there were some smart/digital meters that did still require manual probing even though they read themselves, meters these days are completely remote. They read themselves in intervals and tranmsit that data to the relevant parties to validate. If we have sent you one of those letters regarding upgrading your area to a new meter, then it would be one of the remote ones.
As for the other questions it would depend on what meter they install. If you have any questions you can try reaching out to us here so we can check out the account for you and point you in the right direction.
Thanks,
Mark.
