Interesting, Andy. I am in the same position regards the smart meter not connecting (since install in November last year!).
Octopus have finally agreed to send out an engineer on Tuesday to investigate and hopefully fix.
Fingers crossed!
Being an electrical engineer myself, the meters Octopus installed are EDMI, which come with a 420 Communication Hub in this area.
But if you are in a poor radio reception area, then you need a Dual Band 450 Hub which allows for an additional internal or external aerial to be fitted to improve communication to their network.
I understand the 450 hub has been available since 2019, but NOT APPROVED by Octopus as yet so cannot be installed.
Also, this year should see the introduction of a New Government Developed network for country wide Smart Metering communication called DCC (Data Communications Company) evidently developed by GCHQ.
This will get rid of the two completely different systems in use at the moment, the South of the Country from Manchester down using Telefonica and us in the North and Scotland on Long Wave Radio on the Arqiva Network.
But concerns have recently been raised about EV owners charging at home and the signalling capability on the DCC network to mandate the cheaper tariff switching at night.
It’s still a nightmare out there with Smart Metering, if your in a good signal area it works, but for those in parts of the country where there is poor signal strength, it is a no go for Octopus Go!
By the way, I am just off the promenade in Bispham, Blackpool. You would think a town this size would be covered signal wise, especially as the Lifeboat association use the similar Long Wave Radio network for communication. Its crazy!
It all boils down to a lack of investment in the infrastructure.
