Use Cases

The Shelly PM Mini Gen 3 serves multiple applications across domestic, commercial, and industrial environments. In residential settings, it enables detailed monitoring of individual appliance energy consumption, helping households identify energy-intensive devices and optimise electricity usage. For commercial establishments, the device facilitates sub-metering of specific equipment or departments, supporting accurate cost allocation and energy management initiatives. The compact design makes it particularly suitable for retrofitting into existing electrical installations where space is limited, such as behind power sockets, light switches, or within distribution boards. Additionally, the remote monitoring capability allows facility managers to track equipment performance and receive alerts for abnormal power consumption patterns.

Installation must be performed by a qualified electrician in accordance with local wiring regulations and safety standards. The device should only be operated within its specified technical parameters and must not be used if any physical damage is evident. Regular firmware updates are recommended to maintain optimal performance and security features.
