Your augmented reality.
It is not the data collected, but who has access to that data.
Say the recorded thermal data telling that 2 in 30 homes in a neighbor hood are in excess of average temperature. IE wasting energy.
Who gets this information? The home owner, the local government or the energy corporations you purchase power from.
With all these systems, the real question is "will your computer have the software to interpolate the data" or "will you be first inline to make decisions?".
When was the last time you owned software/hardware that actually read the meter on you home or business?
Good accounting always balances on the sheet, but only when double checks are built in. This system is flawed by design and we are probably just going to have to eat it.
Example: GM foods introduced in products sold to citizens without there full knowledge or disclosure (labeling laws int the US comes to mind as pretty good example of a system gone awry).
