Shelly Pro 3EM Three Phase Energy Meter with Current Transformers

<p>Take full control of your energy usage with the Shelly Pro 3EM, a professional-grade three-phase energy meter built for accurate, real-time power monitoring. Bundled with current transformers for straightforward installation, this DIN rail-mounted device measures voltage, current, active and reactive power, and power factor across all three phases — giving you the detailed insights needed to optimise consumption and cut electricity costs in commercial, industrial, or large residential installations.</p>

<p>With built-in Wi-Fi connectivity, the Pro 3EM streams live energy data directly to the Shelly app on your smartphone or to your preferred monitoring platform. It supports both local and cloud-based access, so you're never locked into a single ecosystem. Seamless integration with Home Assistant, Amazon Alexa, and Google Home means you can incorporate energy data into smart building automations, trigger alerts for abnormal usage, or build custom dashboards using the comprehensive API and MQTT support.</p>

<p>Designed for reliability, the Pro 3EM's compact DIN rail form factor fits neatly into standard Australian electrical panels alongside existing switchgear. It's ideal for monitoring three-phase loads such as HVAC systems, motors, EV chargers, and solar inverters. The included current transformers are clamp-on style, enabling non-invasive measurement without breaking existing circuits.</p>

<p>Installation must be carried out by a licensed electrician, as the device connects within mains electrical panels and must comply with Australian electrical standards. Once installed, you'll have a powerful, always-on energy monitoring solution that pays for itself through smarter energy management.</p>
