Wow! The operative word is “meter”. The smart meters allow large staff reductions at the utility company. You complain about your bill but tie the hands of engineers trying to make the system more efficient and cheaper. The smart meters themselves cannot disconnect electric power to your home. Disconnecting power needs a properly rated breaker — there is a manual disconnect in your house switch box. The next one back is at the transformer serving you and your neighbors. The smart meter would need to have a relay to trip an expensive replacement of your manual disconnect molded case circuit breaker and another relay to re-engage the breaker. The liability associated with such a device controlling all power to your house would be uninsurable at a reasonable cost.
What about those gadgets the utility companies are pushing that allow them to remotely turn off your heating, AC and hot water heater?
