You would think, naively perhaps, that a "smart" meter would do a more accurate job of reporting energy usage than someone manually reading the data and recording the numbers. Guess again, skippy.
At least in the country of Holland, the smart meters seem to have a hard time producing accurate readings and are sometimes wildly off, sometimes several hundred percent over the correct energy consumption levels.
Some of the blame seems to be pointed at energy-saving devices, which supposedly introduce more noise into the system and make accurate readings more difficult.
With smart meters mandated in quite a few countries in the EU, it would appear that someone needs to get their finger out and make some fixes pretty quickly. There are already millions of these types of meters installed worldwide.
