What It Is

The Shelly Plus Wall Dimmer is a UL-certified smart relay that replaces a standard wall switch to give wireless control of dimmable lights. It connects directly to Wi-Fi and Bluetooth, includes an embedded web server, and can operate as a standalone device or integrate with home-automation platforms through MQTT, HTTP or UDP. The unit fits a standard 4-wire installation and features a touch slider for local dimming.

Who It Suits

Homeowners who want schedule-based lighting, remote access from a phone, and voice control via Google Home or Alexa will find the automation engine and scripting editor useful. Installers benefit from automatic calibration and the simple wiring layout. Buyers who need multi-gang switching, control of non-dimmable loads, or a completely offline Zigbee or Z-Wave device should look elsewhere.

The Deciding Spec

UL certification confirms the relay meets North American safety standards for in-wall installation. Without this mark the device cannot be legally used in many residential electrical systems, making the certification the single specification that determines whether the product is the right part for a given project.

Questions about this item

Does the package include the light bulbs or any wiring accessories I need for installation?

The box contains the dimmer relay unit only; you supply your own dimmable LED or incandescent load and standard 4-wire household wiring (live, neutral, load, ground).

Is there more than one version of this dimmer with different load capacities or channel counts?

Only a single model is listed — a 1-channel wall dimmer rated for resistive and dimmable LED loads up to the stated maximum — so there are no alternative capacities or multi-gang versions to choose between.

How quickly does the light respond when I tap the touch slider or use the app?

The built-in high-speed processor executes commands locally, so dimming changes and on/off actions take effect almost instantly without waiting for a cloud round-trip.
