Overview

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.
