Features

Compact Retrofit Design

The Shelly 1 Mini Gen4 is designed to fit into tight installation spaces such as wall boxes, ceiling roses and appliance housings. Its compact dimensions make it suitable for retrofitting existing switches and sockets without adding bulky external hardware.

Dry Contact Relay

The single-pole normally-open relay uses potential-free dry contacts, allowing it to control a variety of electrical circuits independently from the device’s own supply voltage. This makes it suitable for lighting, small appliances, contactors, garage doors and similar automation applications.

Multiprotocol Connectivity

Wi-Fi, Bluetooth, Zigbee and Matter support provide flexible integration into a wide range of smart-home ecosystems. Users can choose the protocol that best suits their installation and connect the device to supported automation platforms and voice assistants.

Matter Certified

Matter certification allows the Shelly 1 Mini Gen4 to integrate with compatible Matter ecosystems, helping simplify cross-platform smart-home control and interoperability.

Smart Schedules and Scenes

Up to 20 schedules can be configured for automated operation, while scenes, local actions, scripting and MQTT provide additional flexibility for more advanced home and building automation workflows.

Wi-Fi and Zigbee Range Extension

The device can function as a Wi-Fi and Zigbee range extender while also acting as a Bluetooth gateway, helping expand connectivity across supported Shelly installations.

• The relay supports dry-contact switching and does not provide power measurement.
• The device requires a 110-240V AC supply.
• Installation on mains-voltage circuits should be carried out by a qualified electrician or authorised installer.
