Smart Meter Comment
This article is a load of crap. I have an understanding about how these meters work. Some are wireless with a range of a few hundred feet. Some are connected to a telephone line. These meters have an IP number. Some manufactures have their own proprietary communications protocol that works similar to IP numbers.
The power to the appliances and etc, pass through a circuit that measures the current. Instead of making a linear electromagnetic field to push a magnetic linear motor unit that drives a sort of simple clock assembly (mechanical meters), the current value is read by a scaling-ramp circuit that feeds a sort of electronic timer. This timer works in kW/hr (Kilowatt Hours). It is a counter. The more current passing through the greater the count rate per unit time frame. After processing and calculating the Kw/Hrs used. This data is sent back to the power company on an independent IP number that has nothing to do with anything in your home. You can shut down all the internet in your home and the power meter will still work as long as the power company independent data line is connected to that meter, or its wireless feature is working.
The power supplies in your devices and appliances have no signal conductibility to the motherboard or processing in appliances. It is an AC supply on the input side of a switching supply that has high isolation to the inverted DC buss inside of the unit. Even a DC buss cannot be infiltrated. The DC buss is regulated and filtered against noise to keep the device or appliance running properly and stable.
As for destroying a power meter, there is not much in these devices that can be dangerous by software access. If someone malicious was to get in to the meter somehow which I doubt very much unless they worked for the power company, or they had the proper setup and huge amount of time, they can only turn off the meter, change the Kw/Hr setting, or reset the readings.
If someone crazy was to break in to a home and put a crowbar across the main power buss before any fuses, and if the power company protection did not trip, the most the guy would have is a huge spark and possibly be injured very badly, or even killed!
As for the two phase voltage coming in to the home, this is directly hard wired from outside to the buss of the breaker panel via the current sensor inside of the meter. This is all hard wired and is not able to have any power diverted. This is high current power and it would take a large automation control high current relay switch-box to start diverting power in the home. I do not know any establishment that would have this type of switch-box unless they are part of a sub station network, or a corporation. And, these boxes would not be allowed to have internet access. These would be on an isolated network only.
I wish before these articles are posted proper research is done. Someone should contact power companies and verify this type of thing to have something official. I am not official for this. I studied electrical engineering and have some knowledge in power systems and power supply design.
There are people who make up all kinds of fright news to attract attention, publish books, and etc., just to bring a lot of attention. Then they have a book or some story, or some software to sell that will supposedly fix things.
