Smart switch Shelly 1 Mini Gen3 1P Wireless 110-240V

The Shelly 1 Mini Gen3 is a compact Wi‑Fi smart switch for wireless control of small electrical loads. Designed for 110–240 V AC systems, it supports up to 8 A switching and consumes approximately 1.2 W. Its very small dimensions (35 × 16 × 29 mm) make it suitable for installation behind wall switches, inside ceiling roses or tight switch boxes, enabling remote control without a hub.

Advantages

The device combines a miniaturized form factor with full-featured functionality: Wi‑Fi control without a hub, Bluetooth inclusion, dry contact support and built‑in scripting (mjS). The Gen3 hardware uses an 8 MB Shelly chip for improved responsiveness and future updates, including planned Matter compatibility. Shelly 1 Mini Gen3 also supports smart schedules, scenes and integration through the Shelly Smart Control app and common voice assistants.
