I had a smart meter on my house in Wisconsin. I agreed to let them cut power to my AC when there was a spike in demand and they needed room. I got a little bit off my bill every month for letting them have that. My AC was on maybe 1 week a year. At that point in time, I was not fretting about the overwhelming power of government, I was trying to be a good citizen and help the power folks balance demand and supply.
I have semi smart readers for water, electricity and power in Washington. Semi smart meaning that a guy in a truck has to drive by every other month to read my usage.
He has to get within about 20 meters for the reader to work.
