## Description

The Shelly i4 Gen3 is a 16-input controller, designed to be used in conjunction with a Shelly smart home network to manually activate and deactivate any created scene, execute complex scenarios involving multiple Shelly devices and synchronise actions. Compact enough to fit behind most wall switches and powered by 110-240V AC current, the i4 Gen3 connects to your Shelly network via WiFi with no hub required and supports multi-click for up to 16 possible actions.

The Shelly i4 Gen3 represents the next generation of i4 scene activation controllers, offering an advance on the Shelly Plus i4 with up to 16 possible actions instead of 12, and an updated processor with increased RAM of 8MB for quicker processing and faster response times.

Designed to be installed under any regular pre-existing 4-button switch and with a range of up to 50m (165ft) outdoors and 30m (99ft) indoors, the i4 Gen3 can be programmed to activate and deactivate anything from a single Shelly-compatible appliance to complex scenes involving multiple Shelly devices. Multi-click offers the possibility of single, double, triple and long-push activations, and its compact size means it can be easily retrofitted in under 10 minutes in even the most tightly-packed electrical boxes and behind most switches.

For a dedicated physical switch, the i4 Gen3 is seamlessly compatible with the Shelly Wall Switches, available in both black and white!

***Please note: The Shelly Plus i4 Gen3 is an input reader device, and does not contain a relay.
