Smart Energy Meter with Contactor control
Shelly EM is a Wi-Fi-operated energy meter with contactor control. It allows you to simultaneously monitor the consumption of any home appliances, electric circuits, and office equipment (lights, power lines, security systems, heating, cooling, etc.) in 2 circuits on the same phase or individually. Shelly EM is perfect for measuring solar energy production, monitoring household consumption, and controlling heavier-load appliances.
Connect Shelly EM to your Wi-Fi network. No HUB required!
Shelly ЕМ monitors monophase electrical systems with up to 2 points simultaneously.
Shelly EM has an integrated 2A relay output for contactor control.
The measurements from Shelly EM are stored in a free cloud for 365 days.
Set custom schedules based on a daily agenda or working hours.
Set custom scenes by combining Shelly EM with your other Shelly devices.
Endless use applications
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.
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.
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.
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.
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.
