go-lifx-mqtt

NOTE: This is a work in progress.

This is a simple MQTT client that listens for messages containing commands and sends them to the LIFX bulbs.

Initially designed to be a replacement for https://github.com/denwilliams/lifx-mqtt. Future versions may support more features.

Running

run make run or go run ./cmd/lifx-mqtt

Building

run make build or go build -o lifx-mqtt ./cmd/lifx-mqtt

Configuration

Using environment variables:

MQTT_URI="mqtt://localhost:1883" MQTT_TOPIC_PREFIX="lifx" ./lifx-mqtt

or from source..

MQTT_URI="mqtt://localhost:1883" MQTT_TOPIC_PREFIX="lifx" go run ./cmd/lifx-mqtt

For development you can create a .env file in the root of the project.

Topics

Assuming the MQTT_TOPIC_PREFIX is lifx:

lifx/set/discover

Starts a discovery of LIFX bulbs on the network. This is done automatically on startup, and periodically in the background, but can be triggered manually if needed.

lifx/set/{id}

Set the state of a bulb matching {id}, where {id} can be seen in the app and is derived from the MAC address (all lower case, without : characters).

Payload Examples

Light Off:

{
  "brightness": 0
}

Light Warm Full Brightness:

{
  "brightness": 100,
  "temp": 2700
}

Light Cool Full Brightness:

{
  "brightness": 100,
  "temp": 6500
}

Light Red:

{"color": "#FF0000"}

Light Green:

{"color": "#00FF00"}

Fade the light out over 10s:

{
  "brightness": 0,
  "duration": 10000
}

TODO lifx/set/{id}/(on|off)

TODO: turn a light on/off without messing with it's state
