I’m right there with you. I’ve gone to greater lengths than my wife would like to reduce our exposure to all forms of radiation that I can measure with this tool.
My empirical measurements show that my smart meter produces effectively nothing compared to my mobile cellular, wifi, microwave and electrical wires spread about the house.
I’ve strategically located my access points to allow the convenience with as little signal strength as possible. I’ve also reduced the output milliwatts to the minimum and still have effective coverage. I hardwire everything that supports it.
I distance myself from my laptop as much as practical and disable the radios in my mobile phone when not needed.
We have poor cell reception and I know the mobile phone increases it’s gain to max trying to reach the tower. This is by far the greatest source. Wifi is quite minimal in comparison.
Electromagnetic, magnetic and radio frequency fields are all very location/environment specific. Get a meter and measure your environment and make adjustments. Your smart meter may have to increase it’s gain to communicate or it may not, like mine. I focus my efforts on reducing exposure while sleeping.
Grounding yourself frequently I believe is also helpful to our bodies. Touch the ground with bare feet and connect wires to the ground system that are in easy reach where you sit and touch the end regularly.
