Shelly EM Gen4
Device identification Device name: Shelly EM Gen4 Device model: S4EM-002CXCEU Device SSID: ShellyEMG4-XXXXXXXX BLE model ID: 0x1036 Short description Shelly EM Gen4 (the Device) is a small form factor smart energy meter using up to 2 current transformers (contactless metering), which allows energy metering the consumption of electric appliances and reporting to a mobile phone, tablet, PC, or home automation system. 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 single dry contact switch for controlling external loads. Shelly EM Gen4 can be accessed, controlled, and monitored remotely from any place where the User has internet connectivity, as long as the device is connected to a Wi-Fi access point and the Internet. Shelly EM Gen4 can be retrofitted into standard electrical wall boxes, next to electrical appliances, power sockets, or in other places with limited installation space. Shelly EM Gen4 has an embedded Web Interface which can be used to monitor, configure, and control the device. The device has multi-protocol wireless MCU which provide Zigbee and Bluetooth connectivity ensuring a secure connection. This device is compatible with Matter. Main features Compact form factor Single phase, two channels measurement Current transformer connection Dry contact relay for contactor control Real-time clock Data logs stored on device for at least 30 days of 1 minute data records Upgraded with an improved processor and the addition of Zigbee connectivity 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 Gen4 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 Gen4 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.
