Descripción
The Shelly EM Mini Gen4 is an ultra-compact smart energy meter designed for accurate, real-time monitoring of electricity consumption. It is ideal for installation in very small spaces, behind sockets, switches or in other areas where standard modules do not fit easily.
This model represents a significant evolution from the previous generation, offering compatibility with Matter, Zigbee, Wi-Fi and Bluetooth, making it extremely flexible for integration with modern smart home systems.
The Shelly EM Mini Gen4 does not directly control the load, but is dedicated to measuring consumption, providing accurate data on voltage, current, active power and active energy. It is an excellent choice for energy monitoring, cost optimisation and consumer diagnostics.
