Re: Cost Benefit Analysis?
Here's a scenario for you - really sunny windy day with lots of over-generation of electricity. A smart meter made by an engineer with a pic controller in it and an old phone so it only costs about £20 more than the original beast.
The electricity price drops to bugger all. Your home system recognises its gone cheap cost it can blue-tooth/wifi into it and see its nice and cheap. You can heat your hot water for near free and granny can fill up her storage heaters without worrying herself to death.
Your system also learns that it can be nice and cheap at night and can do a bit of thinking for itself and heat your water on cheap electricity rather than gas or whatever.
All perfectly possible now - which may explain why the companies are desperate to fit the old 'smart' meters that they effectively got the government to agree to by 'lobbying' cos they know you will never crawl under the stairs to stare at a shit LCD to see if its worth saving a couple of quid by turning the immersion on.
