Use Cases

Power Consumption Monitoring

Power Consumption Monitoring

Monitor the power consumption of connected devices in real-time. This information can be valuable for understanding energy usage patterns and making informed decisions to reduce consumption.

Appliance Health Check

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.

Heavy load control with contactors

Heavy load control with contactors

Besides precise power metering, Shelly EM Gen4 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.
