Smart power meter SHELLY 3EM-63W Gen3 WiFi

Product detailed description

The Shelly 3EM-63W Gen3 is a compact 1/3-channel meter designed for monitoring three-phase installations or three independent single-phase circuits. It is equipped with strong cables and is very easy to install. This small device is ideal for homes, apartments, businesses and photovoltaic installations - wherever accurate monitoring of energy consumption is important.

Versatility of use - one module, many options
The Shelly 3EM-63W Gen3 is the solution for everyone - whether you want to monitor energy consumption in the home, assign consumption to specific departments in the company or supervise the production of energy from photovoltaic panels. The device supports both three-phase installations and three independent single-phase lines, so it fits almost any configuration. In addition, thanks to its four-quadrant metering, the meter records both the energy consumed and the energy delivered, which is useful for applications such as PV and hybrid systems.

Intuitive operation, extensive integration
The module connects to the network via Wi-Fi and Bluetooth - without the need for an external gateway. It can be managed from the Shelly Smart Control app, the web interface or via MQTT, HTTP and WebSocket protocols. All incoming connections are protected by TLS encryption. Data can in turn be exported in CSV or JSON format.

Monitoring and analysis without interruption
The Shelly 3EM-63W Gen3 offers measurement of voltage, current, active and apparent power, power factor and energy - with Class B (IEC 62053-21) accuracy. The built-in clock maintains correct time readings even when internet access is down. Measurement data is recorded locally at 1-minute intervals and stored for at least 7 days, so you have access to your consumption history even if you are temporarily not connected to the cloud.

Automation and security
Shelly 3EM-63W Gen3 allows you to create schedules (up to 20) and configure webhooks (up to 20, each with up to 5 URLs). In addition, local automation allows, for example, to react to instantaneous power consumption and trigger specific actions, and a built-in "no-load threshold" prevents power counting at very low power consumption (less than 30 VA per channel).

Ready for energy from the sun
The Shelly 3EM-63W Gen3 is also ideal for monitoring photovoltaic systems. It allows simultaneous monitoring of energy production and consumption, allowing the operation of the plant to be precisely matched to the temporary availability of energy from the panels. This makes it easier to reduce the grid draw and optimize self-consumption - for example, operating energy-intensive equipment at times of peak sunshine.

Clear information and full control
The device is equipped with LEDs to indicate current status (including Wi-Fi connectivity and OTA updates) and a single button to quickly enter configuration mode or reset to factory settings. It also has a built-in temperature sensor. Plus, it's very easy to install.

Shelly Smart Control App
The meter works with the Shelly Smart Control app to remotely manage devices, view energy usage, and create schedules and automations. You can also use it to track data, view measurement history and monitor energy costs.
