LIFX Binding

This binding integrates the LIFX LED Lights (opens new window). All LIFX lights are directly connected to the WLAN and the binding communicates with them over a UDP protocol.

The following table lists the thing types of the supported LIFX devices:

The thing type determines the capability of a device and with that the possible ways of interacting with it. The following matrix lists the capabilities (channels) for each type:

Thing Type	On/Off	Brightness	Color	Color Zone	(Abs) Color Temperature	(Abs) Color Temperature Zone	HEV Cycle	Infrared	Tile Effects
colorlight	X		X		X
colorhevlight	X		X		X		X
colorirlight	X		X		X			X
colormzlight	X		X	X	X	X
tilelight	X	X	X		X				X
whitelight	X	X			X

Discovery

The binding is able to auto-discover all lights in a network over the LIFX UDP protocol. Therefore all lights must be turned on.

Note: To get the binding working, all lights must be added to the WLAN network first with the help of the LIFX smart phone applications (opens new window). The binding is NOT able to add or detect lights outside the network.

Thing Configuration

Each light needs a Device ID or Host as a configuration parameter. The device ID is printed as a serial number on the light and can also be found within the native LIFX Android or iOS application. But usually the discovery works quite reliably, so that a manual configuration is not needed.

However, in the thing file, a manual configuration looks e.g. like

Thing lifx:colorlight:living [ deviceId="D073D5A1A1A1", fadetime=200 ]

The fadetime is an optional thing configuration parameter which configures the time to fade to a new color value (in ms). When the fadetime is not configured, the binding uses 300ms as default.

You can optionally also configure a fixed Host or IP address when lights are in a different subnet and are not discovered.

Thing lifx:colorirlight:porch [ host="10.120.130.4", fadetime=0 ]

Channels

All devices support some of the following channels:

Channel Type ID	Item Type	Description	Thing Types
abstemperature	Number:Temperature	This channel supports adjusting the color temperature in Kelvin.	colorlight, colorhevlight, colorirlight, colormzlight, tilelight, whitelight
abstemperaturezone	Number:Temperature	This channel supports adjusting the zone color temperature in Kelvin.	colormzlight
brightness	Dimmer	This channel supports adjusting the brightness value.	whitelight
color	Color	This channel supports full color control with hue, saturation and brightness values.	colorlight, colorhevlight, colorirlight, colormzlight, tilelight
colorzone	Color	This channel supports full zone color control with hue, saturation and brightness values.	colormzlight
effect	String	This channel represents a type of light effect (e.g. for tile light: off, morph, flame)	tilelight
hevcycle	Switch	This channel supports starting and stopping the HEV clean cycle.	colorhevlight
infrared	Dimmer	This channel supports adjusting the infrared value. Note: IR capable lights only activate their infrared LEDs when the brightness drops below a certain level.	colorirlight
signalstrength	Number	This channel represents signal strength with values 0, 1, 2, 3 or 4; 0 being worst strength and 4 being best strength.	colorlight, colorhevlight, colorirlight, colormzlight, tilelight, whitelight
temperature	Dimmer	This channel supports adjusting the color temperature from cold (0%) to warm (100%).	colorlight, colorhevlight, colorirlight, colormzlight, tilelight, whitelight
temperaturezone	Dimmer	This channel supports adjusting the zone color temperature from cold (0%) to warm (100%).	colormzlight

The color and brightness channels have a "Power On Brightness" configuration option that is used to determine the brightness when a light is switched on. When it is left empty, the brightness of a light remains unchanged when a light is switched on or off.

The color channels have a "Power On Color" configuration option that is used to determine the hue, saturation, brightness levels when a light is switched on. When it is left empty, the color of a light remains unchanged when a light is switched on or off. Configuration options contains 3 comma separated values, where first value is hue (0-360), second saturation (0-100) and third brightness (0-100). If both "Power on brightness" and "Power On Color" configuration options are defined, "Power on brightness" option overrides the brightness level defined on the "Power on color" configuration option.

The temperature channels have a "Power On Temperature" configuration option that is used to determine the color temperature when a light is switched on. When it is left empty, the color temperature of a light remains unchanged when a light is switched on or off.

MultiZone lights (colormzlight) have several channels (e.g. colorzone0, temperaturezone0, abstemperaturezone0, etc.) that allow for controlling specific zones of the light. Changing the color, temperature and abstemperature channels will update the states of all zones. The color, temperature and abstemperature channels of MultiZone lights always return the same state as colorzone0, temperaturezone0, abstemperaturezone0.

The hevcycle channels have an optional "HEV Cycle Duration" configuration option that can be used to override the cycle duration configured in the light.

LIFX Tile (tilelight) supports special tile effects: morph and flame. These effects are predefined to their appearance using LIFX application. Each effect has a separate speed configuration option.

Full Example

In this example living is a Color 1000 light that has a colorlight thing type which supports color and temperature channels.

The desk light is a LIFX Clean that has a colorhevlight thing type which supports color, temperature and hevcycle channels.

The porch light is a LIFX+ BR30 that has a colorirlight thing type which supports color, temperature and infrared channels.

The ceiling light is a LIFX Z with 2 strips (16 zones) that has a colormzlight thing type which supports color, colorzone, temperature and temperaturezone channels.

Finally, kitchen is a White 800 (Low Voltage) light that has a whitelight thing type which supports brightness and temperature channels.

Either create a single Color item linked to the color channel and define Switch, Slider and Colorpicker entries with this item in the sitemap. Or create items for each type (Color, Switch, Dimmer) and define the correspondent entries in the sitemap.
