DALI ("Digital Addressable Lighting Interface") defines how lighting control gear (eg. fluorescent ballasts, LED dimmers) and input devices (push buttons, motion detectors, etc.) should interoperate. It is standardised in IEC 62386.

IEC 62386 contains several parts. Part 101 contains general requirements for all system components, part 102 covers general requirements for control gear, and part 103 describes general requirements for control devices. Parts 2xx extend part 102 with lamp-specific extensions and parts 3xx extend part 103 with input device specific extensions.

This library has been written with reference to the following documents:

• IEC 62386-101:2014 (general requirements for system components)
• IEC 62386-102:2014 (general requirements for control gear)
• IEC 62386-103:2014 (general requirements for control devices)
• IEC 62386-201:2009 (fluorescent lamps)
• IEC 62386-202:2009 (self-contained emergency lighting)
• IEC 62386-205:2009 (supply voltage controller for incandescent lamps)
• IEC 62386-207:2009 (LED modules)

I do not have copies of the other parts of the standard; they are fairly expensive to obtain. The library is designed to be extensible; adding support for the other parts ought to be easy and self-contained.
