Your smart meter not only spies on phones in your house, it also can lock you out in order to save the world from global warming. That is remote access. Many houses have smart meters. These devices can hack into your power, heater, AC, etc.
Dear @joeyarnoldvn , What is smart meter?
A smart meter is an electricity input monitor. In other words, the device tells you how much power, watts, amps, voltage, energy waves, pulse, is coming into your house.
