Smart meters, what do SMETS2 use to communicate (Suffolk)?

Hamburg

The station used for clocks in Europe is DCF77 at Mainflingen (Frankfurt). The UK is within range of the signal (2000km). I have several devices which use it.

JOOI how is that pronounced? An thorn or Ant horn?

[Rob Morley]

AN-thorn

The Rugby (now Anthorn) and Frankfurt radio signals are different. They just transmit the raw time, and that's it.

The system carried on Radio 4 Long Wave is a different kettle of fish. It allows your energy company to trim the on/off switch times of your Economy 7 (or older systems) to suit them. Not by very much, but enough for them to spread out the switch times by a few minutes either side of the nominal . Clusters of time-switches can also be addressed I think ?

However, the data rate is 24 bits (yes, BITS) a second, so it's a very slow carousel of data. (Imagine when you used to select a Teletext page, and you waited for it to come around, but far far longer !)

I doubt that. It still had a population of 114,400 in 2021.

I was thinking of the GPO Radio station, not the town - where I went to school
