It can work standalone in a local Wi-Fi network or it can also be operated through cloud home automation services. The Device has internal storage for data allowing for later retrieval. The Device has a single dry contact switch for controlling external loads.\u003c\/p\u003e\u003cp\u003ePower 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.\u003c\/p\u003e\u003cp\u003eEnergy Efficiency Optimization: Identify electrical energy consumption patterns and optimize electricity usage.\u003c\/p\u003e\u003cp\u003eAppliance 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.\u003c\/p\u003e\u003cp\u003eCost Management: With the knowledge of power consumption, you can estimate the cost of running specific devices and manage your electricity expenses more effectively.\u003c\/p\u003e\u003cp\u003eSpace-Efficient Retrofitting: Integrate the device into standard electrical wall boxes, behind power sockets, light switches, or other locations with limited space.\u003c\/p\u003e\u003cp\u003eRemote 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.\u003c\/p\u003e\u003cp\u003eLocal 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.
