Shelly PRO EM-50 Wi-Fi
Shelly PRO EM-50 WIFI is an advanced electricity consumption meter that revolutionizes the way you monitor and control electricity consumption in your home, commercial or industrial facilities. Equipped with a single-phase two-channel energy meter, it allows for accurate measurement and reporting of both total energy consumption and voltage, current, active and apparent power in real time.
Reliability and security
Using the latest gen2 firmware technology and LAN and Wi-Fi connectivity, Shelly PRO EM-50 offers flexibility and reliability in operation. It can operate autonomously on a local LAN or Wi-Fi network, as well as integrate with Cloud services for home automation via MQTT, HTTP and WebSocket. All incoming connections are handled via the TLS protocol, ensuring data security.
Complete control of energy consumption
The meter reports both total energy consumption and voltage, current, active and apparent power per phase in real time. The data is stored, allowing it to be read for up to 60 days at one-minute intervals. This allows the user to monitor and analyze energy consumption, allowing informed decisions to be made regarding its efficient use.
Easy configuration
Shelly PRO EM-50 allows remote access, configuration and monitoring by both the user and home automation systems, provided they are on the same network infrastructure. The device has a built-in web interface that allows for convenient customization of its settings. In addition, the easy-to-use interface makes configuring and monitoring the meter easy and intuitive.
