LIFX HTTP API

This project currently has issues with the new 2.0 firmware. Updates pending.

This is an unofficial JSON RESTful API service for controlling LIFX devices. This API adds some reliability that the LIFX gem does not include.

• Mostly synchronous, apart from setting colour
• Supports MDNS

• Ruby 2.0+
• Tested on OS X Mavericks, but should work for other *nix platforms.

• Install the gem: gem install lifx-http
  • On OS X Mavericks using system Ruby: sudo gem install lifx-http
    • If you see this: clang: error: unknown argument: '-multiply_definedsuppress' [-Wunused-command-line-argument-hard-error-in-future] Run export ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future; sudo -E gem install lifx-http
• Run in foreground (no daemonizing yet): lifx-http
  • Be aware that the http server is reachable from other machines as well and is advertised via MDNS
• Test if working: curl http://localhost:56780/lights.json
• Toggle all lights: curl -XPUT http://localhost:56780/lights/all/toggle -d ''
• Set all lights to green:
  • URL params: curl -XPUT "http://localhost:56780/lights/all/color?hue=120&saturation=1&brightness=1&duration=2" -d ''
  • JSON body: curl -XPUT http://localhost:56780/lights/all/color -H "Content-Type: application/json" -d '{"hue": 120, "saturation": 1, "brightness": 1, "duration":2}'
  • Override method by setting _method: curl "http://localhost:56780/lights/all/color?hue=120&saturation=1&brightness=1&duration=2&_method=put"
• Start a slow sunrise effect:
  • curl -XPUT "http://localhost:56780/lights/all/color?hue=35&saturation=0.37&brightness=0.65&duration=10m" -d ''

• selector is either:
  • all for all lights
  • label:[label] for light with label label
  • tag:[tag] for lights with tag tag
  • [light_id] for light with id light_id
• GET /lights - Lists all lights
• GET /lights/{selector} - Lists lights matching selector
• PUT /lights/{selector}/on - Turns lights matching selector on
• PUT /lights/{selector}/off - Turns lights matching selector off
• PUT /lights/{selector}/toggle - Toggle lights matching selector. If any lights in selector is on, it will turn them off
• PUT /lights/{selector}/color - Sets the color for lights matching selector. Color data can be passed as URL parameters or form parameters (JSON)
• PUT /lights/{light_id}/label - Changes the label of light with id light_id
• POST /lights/{light_id}/tag - Adds a tag to the light
• DELETE /lights/{light_id}/tag - Removes a tag from the light
