Integration and connectivity - local and remote monitoring
The Shelly 3EM-63W Gen3 can operate both locally via a Wi-Fi network and remotely via cloud integration or external automation systems. It supports protocols such as MQTT, HTTP, and WebSocket , allowing for flexible use in both simple home installations and advanced energy management systems in businesses. TLS encryption ensures secure data transmission, protecting against unauthorized access. The device also features a web interface that allows for local monitoring and configuration without the need for internet access. Additionally, Shelly Smart Control allows for convenient data management and automation creation via a mobile app or browser.
The meter can be managed via the Shelly Smart Control application.
Thanks to 4-quadrant measurement, the meter records both consumed and released energy.
Practical Applications of Shelly 3EM-63W Gen3
The Shelly 3EM-63W Gen3 is an excellent tool for monitoring real-time energy consumption , both in three-phase installations and in three independent single-phase circuits. It allows you to precisely track the power consumption of specific devices or entire zones, which can reveal sources of high energy consumption and help optimize them . Accurate measurements allow, for example, the quick detection of faulty or excessively energy-intensive devices. Additionally, automation features and webhooks allow you to implement logic to shut down devices during peak consumption periods , translating into real savings and increased energy efficiency. This solution is suitable for both households and commercial sectors, such as server rooms, workshops, and manufacturing plants.
