Re: Why aren't they talking about the advantages?
That's how I look at it ...
I installed solar panels ... and was told that I needed to have a new smart meter installed to get a export tariff.
Meter installed ... The situation is that it works for about 2 - 3 weeks, passing readings to Octopus. Then the signal drops out for a bit and the DCC can't be arsed to notice when it is restored. The DCC put my meter on their 'not working' list, and now Octopus don't get any more reading for the next 2 - 3 months. Octopus then write to me to inform me that *I* haven't sent them any meter readings recently, so they are sending me an estimated bill ...
I send incendiary email to Octopus ...
Octopus then inform the DCC of the problem. The DCC fiddles with something at their end. Readings work for the next 2 - 3 weeks. Rinse and repeat (I think we're on the 3rd cycle of this now ...).
As for the 'in-houe-display' ... I've got no idea. From the time of installation it only gave readings for about 1 hour out of 10 so I threw it in the bin. I get my electricity usage data from the raspberry pi / grafana / inverter reader that I installed when the panels went it.
I'd like to see how Octopus are ever going to use my smart meter to brown me out, or to implement surge pricing to my property. From what I can see this waste-of-time won't have any impact on me (beyond raising my blood pressure ...). It's way too unreliable.
