If you want to live sustainably and save energy, money and carbon emissions, then the Shelly 3EM will work perfectly for you. With the meter, you can monitor the consumption of any circuit, appliance or equipment throughout your home to optimize energy consumption. The product will also be useful if you have solar panels or wind turbines, for monitoring the amount of energy produced.

Optimize energy consumption

With Shelly 3EM, you can check the quality of your electric grid in terms of active power, reactive power, voltage and power factor. Monitor your facility or home to avoid additional expenses or drastic energy drops that can damage equipment and machinery.
