lifx-mqtt

This program synchronizes LIFX devices with an MQTT broker.

Setup

• Figure out the IP addresses of your LIFX devices
• Copy Settings.example.toml to Settings.toml.
• Edit Settings.toml with values matching your setup.
• Try running lifx-mqtt with cargo run.

Now you should be able to view all your configured LIFX devices through e.g. MQTT Explorer once connected to the same MQTT broker.

Topics

The default MQTT topics are as follows:

• /home/lights/lifx/{id}: Current state of the device serialized as JSON
• /home/lights/lifx/{id}/set: Sets state of the light to given JSON

State messages

MQTT messages follow this structure, serialized as JSON:

struct MqttDevice {
    pub id: String,
    pub name: String,
    pub power: Option<bool>,
    pub brightness: Option<f32>,
    pub cct: Option<f32>,
    pub color: Option<Hsv>,
    pub transition_ms: Option<f32>,
    pub sensor_value: Option<String>,
}

Example light state:

{
  "id": "my-light-1",
  "name": "Office",
  "power": null,
  "brightness": 0.5,
  "cct": null,
  "color": {
    "hue": 31.238605,
    "saturation": 0.7411992,
    "value": 1
  },
  "transition_ms": null,
  "sensor_value": null
}
