# DALI Binding

This binding supports controlling devices on a DALI bus (Digital Addressable Lighting Interface) via a [daliserver](https://github.com/onitake/daliserver) connection.

Daliserver supports the Tridonic/Lunatone DALI USB adapter.
As it only provides a thin multiplexer for the USB interface, the DALI messages themselves are implemented as part of this binding.

## Supported Things

Currently, these things are supported:

 - daliserver (bridge)
 - device (single device/ballast on the DALI bus)
 - group (group of DALI devices)
 - rgb (virtual device consisting of three directly addressed devices that represent r/g/b (LED) color channels)
 
This binding was tested on a DALI 1 bus with daliserver 0.2.

## Discovery

Automatic device discovery is not yet implemented.
