## Shelly EM Gen3 + 50A Clamp Provides Real-Time Insights Into The Power Consumption Of Your Connected Devices

The Shelly EM Gen3 is a compact, standalone Wi-Fi/Bluetooth energy meter that clips behind a switch or into a DB enclosure and uses contactless current-transformer clamps (one included, up to two supported) to give real-time insight into the power consumption of connected circuits or appliances. It reports instantaneous voltage, current and power alongside accumulated energy, and can trigger automations or notify the Shelly app when consumption thresholds are crossed. Local data is retained on-device for up to 10 days, extending to 365 days once connected to the Shelly cloud.
