Short description

Shelly DALI Dimmer Gen3 is a smart Wi-Fi/Bluetooth DALI gateway designed to connect and control DALI-compatible lighting systems.
Operating as a single-master DALI application controller, it enables precise brightness control of connected DALI drivers (DT6).
With built-in Wi-Fi, BLE gateway, and LAN integration, it bridges the Shelly ecosystem with DALI lighting for seamless automation and centralized management.

Main features

• Single-master DALI controller for up to 5 DALI bus units
• Supports DALI LED control gear (DT6) with intensity adjustment
• Integrated DALI bus power supply (max 35 mA)
• DALI defaults: power-on OFF; bus failure → lights ON (100%)
• Wi-Fi and Bluetooth connectivity
• BLE Gateway for linking Shelly BLU devices to the Wi-Fi network
• Wi-Fi Range Extender for improved coverage
• Switch/Button input for manual or automated dimming control
• Min/Max brightness calibration for fine control
• Night mode for preset low-brightness operation
• Weekly and advanced scheduling options
• Auto on/off timers and transition duration control
• Supports scripting and custom automation logic
• KNXnet/IP protocol support for professional installations
• Compatible with Alexa, Google Home, SmartThings, and third-party systems
• No hub required – operates locally or via Shelly Smart Control app

*DALI color temperature control (DT8) is not supported.

*External power may be required if more than five DALI units are connected.

Use cases

• Integrate and control DALI lighting systems through the Shelly ecosystem
• Enable DALI dimming control via Shelly mobile app or APIs
• Automate DALI lighting using schedules, sensors, or scripts
• Combine with Shelly Plus Add-on for sensor-based lighting control
• Bridge Bluetooth automation devices with DALI light networks
