The Shelly 1 Gen4 is a compact, powerful and versatile smart relay, designed to be installed behind 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 huge range of other electrical appliances. The 1 Gen4 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.
