Use cases
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.
Energy Efficiency Optimization: Identify electrical energy consumption patterns and optimize electricity usage.
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: Shelly EM Gen3 supports publishing data to Shelly cloud or other cloud based data collection and storage systems. This allows you to monitor power consumption even when you're away from home.
Local Monitoring: Like the rest of the Shelly Wi-Fi line of devices Shelly EM Gen3 allows for local only monitoring and automations. Access stored energy consumption records directly from the device UI. Automate locally with rules based on instantaneous power consumption or energy consumer for a period of time.
Main applications
Residential
MDU (Multi Dwelling Units - apartments, condominiums, hotels, etc.)
Light commercial (small office buildings, small retail/restaurant/gas station, etc.)
If negative readings on a measured circuit are read and are not expected, check the correct installation of the CT (K->L).
Ensure that the device is properly powered:
Check power cables, outlets, and any power indicators on the device.
Inspect Connections:
Verify that all connections, including cables and wiring, are secure and properly seated. Loose connections can lead to functionality issues.
Review Device Settings:
If applicable, check and review the device settings. Ensure that configurations are correct and match your intended use.
Update Firmware/Software:
Check if there are any available firmware or software updates for the device. Keeping the device up-to-date can resolve known issues and improve performance.
Restart or Reboot:
Sometimes, a simple restart can resolve temporary glitches. Turn off the device, wait a few seconds, and then power it back on.
Check Network Connection:
If the device is connected to a network, ensure that the network settings are correct. Test the network connection and consider restarting routers or switches if needed.
Inspect Physical Components:
Physically inspect the device for any signs of damage, overheating, or unusual behavior.
Check Compatibility:
Ensure that the device is compatible with other components in your system, including hardware and software. Incompatibility issues can lead to malfunctions.
Monitor Environmental Factors:
Consider environmental factors such as temperature and humidity.
Inspect Power Supply Quality:
Poor power quality, including voltage spikes or fluctuations, can affect device performance. Consider using a surge protector or voltage regulator if needed.
*These are general troubleshooting steps, and the specific steps may vary based on the type of device or issue you are facing. If the issue persists and you are unable to resolve it, consider reaching out to our technical customer support.
