Smart Wi-Fi Input Controller

The Shelly Plus i4DC is a compact DC-powered module that reads four digital inputs and translates them into smart-home actions. It connects directly to a Wi-Fi network without requiring a separate hub and can be configured locally through its built-in web interface. The device fits behind standard wall switches for clean retrofitting.

Suits scene-based automation, not load switching

Installers who want to trigger scenes, scripts or MQTT/HTTP devices from physical buttons will find the four inputs and multi-click support useful. The controller does not contain relays, so it cannot switch lights, motors or other loads directly. Buyers needing on-board switching capacity should look at a relay-equipped model instead.

Four inputs with 12 multi-click actions

Each of the four digital inputs recognises up to 12 distinct click patterns, giving ample headroom for complex trigger scenarios. The ESP32 processor executes commands and notifications with minimal latency. Headroom ends when a project demands more than four monitored contact points or requires the unit to switch power itself.

Questions about this item

Will the Shelly Plus i4DC work with my existing 12 V DC wiring behind the wall switch?

Yes, this is a DC version designed for direct-current circuits such as 12 V systems commonly found behind wall switches.

Can I keep my current mechanical switches and use them to trigger the four inputs?

Absolutely. The device reads the state of up to four dry-contact switches so your existing buttons become smart triggers without replacement.

How do I verify the ESP32 processor has booted and the inputs are reporting correctly after installation?

Open the built-in web interface or the Shelly Cloud app; each of the four inputs shows real-time on/off status and the multi-click count up to 12 actions.
