Use cases
Power Consumption Monitoring: The primary purpose is to 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.
Energy Efficiency Optimization: Identify energy-hungry appliances and optimize their usage to improve overall energy efficiency in your home or workspace.
Appliance Health Check: Keep track of the power usage of individual appliances to assess their health and performance over time. Sudden spikes or changes in power consumption may indicate issues with the appliance.
Cost Management: With the knowledge of power consumption, you can estimate the cost of running specific devices and manage your electricity expenses more effectively.
Space-Efficient Retrofitting: Integrate the device into standard electrical wall boxes, behind power sockets, light switches, or other locations with limited space.
Remote Monitoring: Like the Shelly PM Mini Gen3, the EM Mini Gen4 also supports remote access. This allows you to monitor power consumption even when you're away from home. The device shares similarities to Shelly EM Gen3

Preventative monitoring
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 Mini Gen4 will fit anywhere you need it to and can immediately report the increase in energy consumption, saving you additional expenses on repairs or equipment replacement.

All connected electrical appliances we don't use during the night or forgotten switched-on lights generate unnecessary energy. Shelly EM Mini Gen4's smart energy metering will help you identify and eliminate any redundant energy consumption from each connected appliance around your home or facility. Together with smart scenes, you can use Shelly EM Mini Gen4's data to trigger scenarios, such as turning off appliances during a spike to protect them or during the night to save energy. *
