The Shelly Pro 3EM can calculate two-phase power consumption: the energy produced and consumed on each of the three phases. The device can also be configured to measure three separate circuits of a single-phase electrical system. It displays the quality of your electrical network in terms of active power, reactive power, voltage, and power factor.\u003cbr\u003e\n\n\u003c\/li\u003e\n\n \u003cli\u003eLocal Control - Thanks to the Shelly Pro 3EM's scripting capabilities and webhooks, you can easily control other Shelly or Wi-Fi devices on your local network. Use these features to set precise parameters for heating, cooling, or EV charging based on your PV generation, and automatically disconnect your devices from power consumption. All of this works without the need for a cloud.\u003cbr\u003e\n\n\u003c\/li\u003e\n\n \u003cli\u003eSolar panel monitoring and control - See how much energy your solar panels or wind turbines are generating and save effortlessly. Shelly Pro 3EM provides real-time information on the efficiency of your solar and wind energy system, as well as historical data on energy generation and energy consumption from the past 60 days—in one-minute increments. This allows you to control the energy flow and use your solar panels and wind turbines as efficiently as possible. Next, you can connect Shelly Pro 3EM to your other Shelly devices and create scenarios to perform desired actions, such as switching off appliances or activating an alarm.\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003c\/p\u003e\n\n\u003cp\u003e Support:\u003c\/p\u003e\n\n\u003cp\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003e Full compatibility – Shelly devices are compatible with Alexa, Google Home, Android, and iOS.
