Shelly i4 Gen3 4 Input Smart Scene Controller

The SHELLY-I4-GEN3 represents the third generation of smart Wi-Fi switch inputs from Shelly, designed to seamlessly integrate into modern home automation systems. This compact device enables manual activation or deactivation of created scenes, execution of synchronised actions, and implementation of complex trigger scenarios. With its improved processor and increased memory compared to previous versions, the device delivers enhanced performance while maintaining a form factor small enough to fit behind standard wall switches. This versatile input device allows control of other connected Shelly switches, sensors, or HTTP and MQTT-controlled devices through four independent inputs. The unit can be retrofitted into standard electrical wall boxes, behind power sockets, light switches, or other locations with limited space. Remote access and monitoring are possible from any location with internet connectivity when the device is connected to a Wi-Fi router, providing flexible control options through its embedded web interface.

Use Cases

The SHELLY-I4-GEN3 excels in residential automation scenarios where multiple control points are required. It serves as an ideal solution for retrofitting traditional lighting systems with smart capabilities, allowing users to maintain existing switches while adding smart functionality. The device facilitates complex automation sequences where multiple actions must be synchronised across different systems. Its compact design makes it particularly suitable for installations where space is limited, such as behind existing light switches or within crowded electrical boxes. The four independent inputs enable comprehensive control schemes for lighting scenes, security systems, and environmental controls throughout residential or small commercial spaces.
