Overview
Shelly PM Mini Gen3 is an ultra-compact Wi-Fi smart power meter designed for precise, real-time energy monitoring of electrical circuits and appliances. It is small enough to fit behind wall switches or sockets, making it ideal for discreet retrofits where space is limited and switching control is not required.
Built on the ESP-based Shelly Gen3 platform with increased flash memory, the device delivers fast local response and reliable long-term operation. It provides power and energy monitoring only and contains no internal relay, meaning it does not switch loads. The module works without a hub, integrates directly with Home Assistant and other automation platforms, and supports open protocols for local and cloud-based energy analysis.
