Shelly Pro 3EM CT63 3x63A 3-Phase Wi-Fi/Ethernet Energy Meter with Current Transformers

The Shelly Pro 3EM CT63 is a professional-grade, three-phase energy meter designed to give you a precise and detailed understanding of your home's electricity consumption. Mounted directly onto a DIN rail in your electrical panel, it measures the instantaneous voltage, current, and power for each phase in real-time. This allows you to monitor not just your total usage, but also the consumption of individual high-power circuits or even the energy generated by your photovoltaic system, providing a clear picture of where your energy is going.

Built for the modern smarthome, the Pro 3EM connects to your network via both Wi-Fi and a stable, wired Ethernet connection. This robust connectivity ensures it integrates seamlessly with leading smarthome ecosystems like Home Assistant, Google Home, and Amazon Alexa. The device can store up to 60 days of detailed energy data directly on-board, and its real-time clock ensures accurate logging even if your internet connection is temporarily lost. This makes it a powerful tool for creating custom automations, optimizing your energy usage, and keeping your utility bills in check.
