Smart wall dimmer for home automation

The Shelly Plus Wall Dimmer is a UL-certified smart dimmer that connects directly to Wi-Fi and Bluetooth. It fits a standard 4-wire installation and pairs through the Shelly Cloud App with automatic calibration for sensor distance and sensitivity. The device includes an embedded webserver and supports MQTT, HTTP and UDP protocols for integration with various automation platforms.

Suits integrators and DIY automators.

This dimmer works for installers who want quick Bluetooth inclusion and scripting via a JavaScript editor for custom automations. It suits households using Google Home or Alexa for voice control and sunrise or sunset scheduling. Buyers whose lighting circuits lack a neutral wire or who need a purely local, non-cloud fallback should look at other solutions.

Controls dimmable loads up to the rated maximum

The unit handles dimmable LED, incandescent and halogen loads within its specified rating, providing smooth brightness adjustment through the touch slider or app. It runs timers, schedules and scripts without an external hub. Circuits that exceed the device's maximum load or use non-dimmable drivers will not operate correctly and require a different control method.

Questions about this item

What type of wiring must already be in the wall box for the 4-wire design to connect?

The dimmer requires a neutral, live, load and ground conductor — four wires in total — so the existing wall box must provide all four for the device to operate.

Will the dimmer still respond to the touch slider if the home Wi-Fi network goes down?

Yes, the unit functions as a standalone device with an embedded webserver, so local control via the touch slider continues even when the cloud connection is lost.

How can I verify the automatic calibration completed successfully after installation?

Open the Shelly Cloud App, add the device through Bluetooth inclusion, and the app will display a confirmation once the sensor distance and movement sensitivity calibration finishes.
