Description

Despite its compact size, the Shelly Mini 1 Gen4 can control devices with loads up to 8A, making it ideal for lighting circuits and small household appliances. It installs and configures in minutes, offering a wide range of possible uses across different environments. You can operate it as a standalone device or integrate it into coordinated “Smart Scenes” alongside other Shelly products throughout your home or office.

This version is the Gen4 model of the Shelly Mini 1, building on the previous Gen3 generation. While it maintains all the capabilities of the Gen3, it introduces an upgraded chipset and expanded RAM for faster performance and more advanced scripting options. Unlike the Gen3 units, the Shelly Mini 1 Gen4 also includes out‑of‑the‑box compatibility with Zigbee and Matter, alongside its standard WiFi and Bluetooth connectivity. It can even maintain these connections at the same time, enabling it to work within a broader WiFi‑based Shelly system while being effortlessly integrated into an existing Zigbee or Matter network.
