Smart switch Shelly PM Mini Gen3 Wireless 110-240V 1.2W

The Shelly PM Mini Gen3 is a compact Wi‑Fi smart power meter and single‑channel switch for AC 110–240 V installations. Designed to fit behind wall switches or sockets, it provides precise real‑time power monitoring while allowing remote on/off control of a single circuit. The device is part of Shelly’s Gen3 series, uses an 8 MB Shelly chip for improved responsiveness, and requires no hub for Wi‑Fi operation; Bluetooth inclusion is also supported.

Advantages

The unit combines a very small footprint (34 × 16 × 29 mm) with accurate power metering and reliable switching up to the device’s rated current. Its 8 MB memory and updated firmware platform improve speed and allow future upgrades, including planned Matter support. Built‑in scheduling, URL actions and mjS scripting enable automation and integration with other smart devices. The device reports consumption trends to help detect abnormal energy increases and supports Shelly Smart Control and common voice assistants for unified control.

Suitable for

• Monitoring and switching individual lights and small household appliances
• Retrofit installations behind switches and sockets where space is limited
