Adrian I forgot about the smart meter issue we had ours fitted about 6 years ago within 3 weeks of changing supply, from that day it was never used until we changed to Octopus last year then suddenly everything works. We had actually forgotten all about it after so long. I really thought we’ll they can’t be of any use but they are fantastic for monitoring your use and your EV but yeah now I believe getting one is more of an issue. Like every thing you can have it unless you need it.
