A daemon with a JSON-RPC API to control your light bulbs
lightsd acts a central point of control for your LIFX_ WiFi bulbs. lightsd should be a small, simple and fast daemon exposing an easy to use protocol inspired by how musicpd_ works.
Having to run a daemon to control your LIFX bulbs may seem a little bit backward but has some advantages:
.. _LIFX: http://lifx.co/ .. _musicpd: http://www.musicpd.org/
lightsd discovers your LIFX bulbs, stays in sync with them and support the following commands through a JSON-RPC_ interface:
The JSON-RPC interface works on top of TCP/IPv4/v6, Unix sockets, or over a command pipe (named pipe, see
lightsd can target single or multiple bulbs at once:
lightsd works and is developed against a variety of LIFX firmwares from the oldest ones to the newest ones.

lightsd is packaged for Mac OS X, Arch Linux, Debian based systems and OpenWRT. Check out https://docs.lightsd.io/latest/ for installation instructions and a walk-through some interactive examples.
lightsd and monolight, an user interface for a programmable button array, were presented at Fosdem 2017. Check out the slides for a presentation of lightsd's capabilities, architecture and an example of project built with lightsd: https://downloads.lightsd.io/slides/fosdem/fosdem_2017.pdf.
lightsd aims to be highly portable on any slightly POSIX system and on any kind of hardware including embedded devices. Hence why lightsd is written in C with reasonable dependencies:
lightsd is actively developed and tested from Arch Linux, Debian, Mac OS X, OpenWRT and OpenBSD; both for 32/64 bits and little/big endian architectures.
Native Windows support has been kept in mind, but isn't really the focus.
Feel free to reach out via email or irc (
#lightsd_ on Freenode, insist if I don't reply). As the project name implies, I'm fairly interested in other smart bulbs.
