Shelly DALI Dimmer Gen3 WiFi Operated Smart Relay

The SHELLY-DALI-DIMMER-GEN3 represents the third generation of advanced DALI lighting control from Shelly, engineered for seamless integration into modern smart building infrastructures. This compact device enables sophisticated dimming and control of DALI-2 compliant lighting fixtures, offering both wireless and wired connectivity options for maximum flexibility. Its design facilitates installation in confined spaces such as in-wall enclosures or suspended ceilings, making it an ideal solution for retrofitting existing lighting systems or deploying in new construction projects.

With support for KNX integration via KNXnet/IP communication, the device bridges the gap between DALI lighting networks and comprehensive building management systems. This allows for centralised monitoring and control alongside other building functions. The inclusion of Wi-Fi and Bluetooth connectivity provides alternative local control methods, while the powerful internal processor supports advanced automation features including scripting, scheduling, and real-time notifications through webhooks.
