Re: I want one!
Read this carefully ...
You do not need a smart meter to get that information. Really, it just doesn't need it, and all the outright lies (which is what most of the publicity stuff is) won't change that.
A clip-on meter will give you a good idea, though a better quality one will work all the time and take into account power factor.
Your inverter on the solar panels will tell you what it's generating - that's a standard function, but may not have been explained to you, or perhaps the f***tards stuck it somewhere stupid (like the attic) where you can't get at it - ask the installers to make it possible for you to read this information, it may need a remote display.
Besides, even if none of this covered it, none of what you ask for actually needs what the meters being talked about can do. Few are worried about the accurate and real time usage information - yes that's useful. The variable rate tariffs are perhaps a bit controversial given that they are intended to be price rationing - ie hike the price until the poor cut back on usage.
But, the smart metering is about huge data collection - knowing your consumption by the half hour for every day of every year can tell a lot about your habits, and would be "quite valuable" to certain types (think what advertisers could do with it, or criminals). Yes we're assured it will be secure - but we don't trust that (the law can be changed, and it's too juicy a target) and collecting it isn't needed as all that is needed is (say) monthly totals for each register* (ie how much you used at each rate).
* Register is the industry term for the "totaliser" bit - the numbers you can read. We've have multi-register metering (think economy seven) for many decades - but that didn't need the intrusive and security risk data slurping these smart meters have built in.
There is one actual benefit - though that is in itself also a downside. These meters can be remotely switched between pre-pay and credit modes. This means it's quicker and cheaper to switch someone from pre-pay to credit mode. The downside is that it's also quicker and easier to switch from credit mode to pre-pay - so find yourself struggling with the bills, hey presto you find you're suddenly part of the pre-pay crowd with all that entails. Of course we all believe the "strong safeguards" will be properly applied don't we ?
And on that last one, we all believe the "strong safeguards" will never fail to prevent an incorrect remote supply disconnection when someone clicks the wrong button on some system somewhere and "click" - that's your power off and it's now down to you to persuade them that they've made a mistake.
