Eon just called and replace my meter with an Ampy 5246C.
Just in passing, the chap mentioned that it runs on GMT for Economy 7, so
will switch at 0700 when we change the clocks. Means that stuff that I do
before 0800 now will be on the higher rate.

The old meter was switched by radio signal and ususally switched at 0803
all year round.
Typical that modern technology can't do what the old stuff did - well, it
could but... It could have been switched via mains, I'd have thought.

I've seen two different versions of E7 meters in different areas, both
radio-switched:

1. with the night rate from 01:00 to 08:00 clock time, all year round;

2. with the night rate from 00:30 to 07:30 in the winter and 01:30 to
08:30 in the summer.

No idea why. Item 1 was about 16 years ago, but when I had it
installed, it was considered to be better than the mechanical ones
that behaved as item 2 still does.
