Short description

Shelly Plus i4 is a smart Wi-Fi switch input that allows you to manually activate or deactivate any created scene, run synchronized actions, or execute complex trigger scenarios. You can use Shelly Plus i4 to control other connected Shelly switches, sensors, or HTTP and MQTT-controlled devices. Small enough to fit behind every wall switch, Shelly Plus i4 can show the status and control the action of four inputs.

You can access and monitor Shelly Plus i4 remotely from any place where you have internet connectivity, if the Device is connected to a Wi-Fi router and the Internet.
