Short Description
The Shelly DALI Dimmer (Device) is a gateway device that bridges the Shelly ecosystem and APIs with a DALI lighting network. It enables control of DALI-compatible light sources equipped with DALI control gear.
In terms of DALI, it functions as a single-master application controller supporting LED control gear (Part 207), operating independently on the bus without sharing it with other DALI devices. The Device controls all connected DALI control gear as a single group using broadcast messages.
The Device includes an integrated bus power supply capable of powering up to X non-powered bus units.
It can be accessed, controlled, and monitored remotely from any location with internet connectivity, provided it is connected to a Wi-Fi router and the Internet.
An embedded Web Interface allows users to monitor and control the Device, as well as adjust its configuration settings.
