Interface to DALI lighting systems

Project description

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)

  • IEC 62386-301:2017 (particular requirements for push button input devices)

  • IEC 62386-303:2017 (particular requirements for occupancy sensor input devices)

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.

The dali.memory module supports the extended memory bank specifications created and maintained by the Digital Illumination Interface Alliance:

  • DiiA DALI Part 251 — Memory Bank 1 Extension

  • DiiA DALI Part 252 — Energy Reporting

  • DiiA DALI Part 253 — Diagnostics & Maintenance

Python versions supported

This library currently requires Python version 3.7 or later.


Some of the code in this project is experimental and its API is subject to change. Modules with stable APIs are noted below.
