## Description

The Shelly 1 Gen4s are compact smart switches that offer efficient and flawless remote control over ordinary electrical appliances such as lamps, heaters, motorised blinds and more. Engineered to be easy to install and compact enough to be retrofitted behind your light switch or socket, the Shelly 1 Gen4 features out-of-the-box connectivity over WiFi, Bluetooth, Zigbee and Matter, and can be controlled remotely via the free mobile app or integrated seamlessly into a smart scene or schedule involving multiple connected Shelly devices. This is a 2 pack.

Shelly's 1 Gen4 is a compact, powerful and versatile smart relay, designed to be retrofitted into any existing electrical appliances to connect them to the internet and integrate them into a wider smart ecosystem. The 1 Gen4 features a single channel and can manage up to 16A, making it an ideal option for lighting, heating, bi-directional motors (roller shutters, blinds) and a wide range of other electrical appliances.

This relay represents an advancement on the previous generation of Shelly devices such as the Shelly Plus 1 Gen3, featuring upgraded memory and a revamped processor for improved responsiveness and a wider range of scripting capabilities for even more customisation options. The Gen4 range also focuses on multi-protocol compatibility, with all Shelly products in the Gen4 range offering out-of-the-box connectivity over WiFi, Bluetooth, Matter and Zigbee; this means that a Gen4 Shelly device can either connect to the wider network over standard home or office WiFi with no extra hubs required, or seamlessly integrate into a pre-existing Matter or Zigbee network. Crucially, these protocols can all work simultaneously from a single relay such as the 1 Gen4, offering a truly integrated, customisable and easily installed smart automation experience.

This bundle includes 2 x Shelly 1 Gen4.
