Shelly 1 Mini Gen3 is an ultra-compact Wi-Fi smart relay designed for controlling lights, garage doors, irrigation systems, and small electrical appliances. Its miniature form factor allows it to fit behind wall switches or sockets, making it ideal for discreet retrofits where space is limited.

Powered by the ESP-based Shelly Gen3 platform, it features improved processing performance and increased flash memory for enhanced stability and future firmware support. The relay supports potential-free (dry contact) switching, works without a hub, and integrates directly with popular platforms such as Home Assistant, Alexa, and other automation systems via Wi-Fi, Bluetooth, and open protocols.
