I'm sure that's right. I think we've all learned something, but we've kicked this one to death!Anyway, returning to how this discussion about my meter started, the point is that it supports a dual-tariff (such as my E7) without being (or, at least, without being used as) a 'smart meter' - so it's simply not true (in a literal sense) that a 'smart' meter is the only possible option for those whose RTS has (or soon will) stopped working. However, as I've said, whether suppliers would be prepared to install anything other than a 'smart' meter is a rather different question!
