Smart dimmer relay pack

The Shelly Plus Wall Dimmer four-pack provides UL-certified Wi-Fi and Bluetooth relays for residential lighting control. Each unit fits a standard wall box and connects directly to a home network without a separate hub. The built-in touch slider allows manual dimming while the app handles scheduling and automation. Integrators benefit from a simple four-wire installation and automatic calibration.

Upgrade from basic switches

These relays replace single-pole on-off switches or non-connected dimmers that lack scheduling and remote access. The jump is worthwhile when you want voice control via Google Home or Alexa, sunrise-sunset timing, or custom scripts through the JavaScript editor. Existing wiring is reused, so no new cabling is required for the upgrade.

Suits DIY and pro installs

Homeowners and electricians who need app-based dimming, timer functions, and multi-protocol integration (MQTT, HTTP, UDP) will find the pack convenient. Buyers who require multi-gang switching, fan-speed control, or compatibility with proprietary hub-only ecosystems should look at other solutions. The devices operate as standalone units or as components in larger automation systems.

What is the common step installers miss when pairing the Shelly Plus Wall Dimmer via Bluetooth?

Users often skip the automatic calibration step in the Shelly Cloud App, which adjusts the touch slider's distance and movement sensitivity for reliable dimming control.

The manufacturer provides a 2-year parts warranty for each Shelly Plus Wall Dimmer relay in the 4-pack.
