I've seen videos of new home power systems including power usage monitoring and reporting, which is said to allow people to check their power usage and change their behaviour in response. With these newest systems, including solar power and backup batteries, people are able to switch to batteries and solar when it suits them, to minimise their bills.
This is all good stuff, but it assumes that people will be willing to keep checking on their power and make decisions about whether they should be on battery power, solar or grid supply at any given time. The assumption behind such a system is that people are merely unable to do this, not unwilling. I think you'll find, though, that most people would rather have a system that attempts to minimise their power bill automatically, as long as it delivers reliable power.

PPS - I prefer automation over manual tasks in most things, where possible.
