Shelly 1 Mini Gen4 compact dry-contact smart relay
The Shelly 1 Mini Gen4 is a smart relay Dry contact and the smallest wireless smart home device of its kind in the world. It controls a lighting circuit or a wide variety of loads up to 8 A.
Installed behind a wall switch, it turns that switch into a smart switch you can control remotely and by voice. It tracks how long a light was on, supports unlimited on and off timers, and alerts you to a fault.
Shelly is small enough to fit behind a standard switch, inside a light fixture or in a junction box. The switch keeps working as usual, while Shelly adds a full range of smart home capabilities, making it just as useful at home and in the office as in industrial settings.
The Gen4 model adds Bluetooth, a more powerful processor, Zigbee and Matter support, and advanced software options for developers.
