Product description: Shelly Pro 3EM-3CT63 - single/three phase LAN/WiFi/Bluetooth energy meter
The Shelly Pro 3EM-3CT63 is a single-phase/three-phase electricity meter designed for use in both residential and industrial installations. It allows you to monitor three independent single-phase circuits or one three-phase circuit within a single installation. The combination of precise measurements and access to modern communication technologies significantly improves the comfort and reliability of energy management. The device has a real-time clock , which is useful in the event of a loss of connection to the SNTP server. The Shelly Pro 3EM-3CT63 has a measurement accuracy of 1%. Users can store historical data on the device for 60 days with a resolution of 1 minute. The controller uses WiFi/Bluetooth or LAN for communication, making it ideal for locations with limited wireless access. The device is compatible with Amazon Alexa, Google Home, and iOS voice assistants, as well as with smart home systems such as Home Assistant .
Attention!
The device does not have a built-in relay. The contactor is controlled via the Shelly Pro 3EM Switch Add-on module, which must be purchased separately.

Solar energy management and consumption monitoring throughout your home
The Shelly Pro 3EM-3CT63 can be used as a tool for monitoring energy consumption throughout the home . If the home is equipped with photovoltaic panels, the user can record measurements of the energy generated by the system and drawn from the grid. This is helpful if you want to optimize energy consumption and ensure maximum utilization of solar energy resources . thereby reducing dependence on mains power and reducing daily living costs.
Shelly Pro 3EM-3CT63 enables you to make informed decisions about reducing energy costs and improving efficiency.
The meter allows you to monitor the energy used while charging electric vehicles.
Monitoring the energy used to charge electric vehicles
The device can be a very helpful tool for owners of electric cars, among others. Thanks to the built-in monitoring function, users can not only analyze the vehicle's energy consumption but also better manage operating costs. Shelly Pro 3EM helps adjust the schedule and optimize the energy consumption needed to fully charge the battery. The meter also allows for analyzing long-term consumption trends , allowing for even more accurate forecasting and minimizing vehicle charging costs.
