Monitor and save energy from anywhere

Unlock the power of smart energy use with detailed insights into your appliances' power consumption patterns. Integrate Shelly EM Gen3 into standard electrical wall boxes, behind power sockets, light switches, or other places with limited space. By identifying how and when your connected appliances use energy, you can optimize usage for maximum efficiency and lower your electricity bills.

Use cases

• Total power monitoring - Know how much energy your home consumes with Shelly EM Gen3! The perfect solution for one-phase homes, Shelly EM Gen3 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 Gen3 and save energy by automatically switching off non-essential appliances.
  
• Heavy load control with contactors - Besides precise power metering, Shelly EM Gen3 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.
  
• Appliance Health Check - Monitor the power usage of your appliances to ensure optimal performance and longevity. By tracking individual energy consumption patterns, you can proactively identify potential issues before they become costly problems. Unexpected spikes or shifts in power usage are early warning signs that an appliance may need attention, allowing you to maintain efficiency and avoid downtime.
