Short Description
The Shelly DALI Dimmer (the Device) is a gateway device between the Shelly ecosystem and APIs, and a DALI network of lights. It can control DALI-capable light sources that contain DALI control gear.
In terms of DALI, it is a single-master application controller, supporting LED control gear (Part 207), which does not share the bus with other DALI control devices. The Shelly DALI Dimmer controls all connected DALI control gear as a single group using broadcast messages.
The device contains a bus power supply capable of controlling 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.
It features an embedded Web Interface for monitoring and controlling the device, as well as adjusting its settings.
