Short Description
Shelly i4 Gen4 is a smart Wi-Fi switch input controller that allows you to manually activate or deactivate any created scene, run synchronized actions, or execute complex trigger scenarios. You can use Shelly i4 Gen4 to control other connected Shelly switches, sensors, or HTTP and MQTT-controlled devices. Small enough to fit behind every wall switch, Shelly i4 Gen4 can show the status and control the action of four inputs.
You can access and monitor Shelly i4 Gen4 remotely from any place where you have internet connectivity, if the device is connected to a Wi-Fi router and the Internet.
You can retrofit the device into standard electrical wall boxes, behind power sockets, light switches, or into other places with limited space.
Shelly i4 Gen4 has an embedded Web Interface that you can use to control it and set it up.
The device has multi-protocol wireless MCU which provides Zigbee and Bluetooth connectivity, ensuring a secure connection.
This device is compatible with Matter.
