        Endless use applications

        use cases
        Power consumption analysis for cost optimization

        All connected electrical appliances we don't use during the night or forgotten switched on lights generate unnecessary energy. Smart energy metering will help you identify and eliminate any redundant energy consumption from each connected appliance around your home or facility.

        Total power monitoring

        Know how much energy your home consumes with Shelly EM! 
        The perfect solution for one-phase homes, Shelly EM can make a large difference in your savings by constantly monitoring the overall power in your breaker box and giving you immediate control over your current consumption. 
        Connect a contactor to Shelly EM and save energy by automatically switching off non-essential appliances. 

        use cases
        Heavy load control with contactors

        Besides precise power metering, Shelly EM allows contactor control of heavy-load appliances such as powerful water heaters, hot tubs, heat pumps, and large kitchen appliances. This way, you can both monitor and control the consumption of larger appliances around your home or facility and maximize your savings.

        Solar panels monitoring and control 

        Keep track of how much energy your solar panels and wind turbines are generating and save effortlessly. Shelly EM provides real-time information about the efficiency of the solar and wind energy system, as well as historical data on how much energy has been generated and consumed. This helps you control the energy flow, getting the most out of your solar panels and wind turbines. To take it a step further, connect a contactor to Shelly EM, so you can switch off automatically non-essential appliances in your home, in order to save energy.

        use cases
        Preventative monitoring

        When an electrical appliance is damaged, it doesn't simply stop working. Usually, it increases the amount of energy used in an attempt to compensate for its operational capacity. Since there is no visible difference in its performance, it might take months before you can identify a problem, leading to inefficiency and wasted energy. Shelly EM, however, will immediately report the increase in energy consumption and save you additional expenses on repairs or equipment replacement.
