Shelly 1 Mini Gen4
Shelly 1 Mini Gen4 is an ultra-compact 1-channel smart relay designed for retrofit installations behind wall switches, sockets, and tight electrical back boxes. It provides reliable on/off control for lighting and small electrical loads, while the dry contact (potential-free) output allows flexible switching of both mains and low-voltage control circuits, such as contactors, gates, or automation inputs.
As a Shelly Gen4 multi-protocol device, the 1 Mini Gen4 supports Wi-Fi, Zigbee, Bluetooth, and Matter connectivity, allowing it to integrate into a wide range of smart home ecosystems. It can operate hub-free via Wi-Fi or Matter, or as part of a Zigbee mesh network, while supporting advanced automation features including schedules, scenes, MQTT, webhooks, and custom scripting for powerful local control.
