Benefits are too many.

But, I just have one concern regarding the maximum (wireless radiation) permissible exposure limit (of 610 µW/cm2) to be followed and tested by smart meter manufacturing industries.

As, we can only talk about the limitations and disadvantages after using it for a decade.

That's a good point Raj Gaurav raised , lets also bring the limitations and possibilities to improve the effectiveness of the Smart Energy Meters , besides their utility.   

Hello RG Colleagues,

Great day!

Thanks a lot for your valuable share.

About Smart Energy Meters!

"Smart energy meters are the next-generation meters that provide more precise and exact amount of electricity consumption. They are generally installed at households or in enterprise infrastructure to maintain detailed statistics about energy consumption. A smart energy meter works as an electrical meter that measures and provides feedback of the power consumed to the electricity supplier. It is also useful for customers as they too can monitor the amount of power used. This two-way communication capability is the most important feature which enables the parties involved (consumers and electricity suppliers) to keep track of real-time energy consumption. There are several other benefits of using smart energy meters. These meters send details of the energy used to the electricity suppliers, helping them to produce accurate bills; the consumers can control the power consumed and monitor their power consumption habits; and smart energy meters help in reducing carbon emission that results from using energy..."

Hello Prof. Jacic,

Great day!

Thanks  a lot for your kind comment.

Today, Z-Wave Smart Energy Meter are also applying with Z-Wave Devices.
