Shelly DALI Dimmer (the Device) is a gateway device between 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. Shelly DALI Dimmer controls all connected DALI control gear as a single group with broadcast messages.
The Device contains a bus power supply with possibility to control up to X non-powered bus units.
The Shelly DALI Dimmer can be accessed, controlled, and monitored remotely from any place where the User has internet connectivity, as long as it is connected to a Wi-Fi router and the Internet.
It has an embedded Web Interface which can be used to monitor and control the Device, as well as adjust its settings.
