LIFX Binding

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

LIFX E27

Supported Things

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

Device Type Thing Type
Original 1000 colorlight
Color 650 colorlight
Color 1000 colorlight
Color 1000 BR30 colorlight
LIFX A19 colorlight
LIFX BR30 colorlight
   
LIFX+ A19 colorirlight
LIFX+ BR30 colorirlight
   
LIFX Z colormzlight
   
White 800 (Low Voltage) whitelight
White 800 (High Voltage) whitelight
White 900 BR30 (Low Voltage) whitelight

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 Color Temperature Color Temperature Zone Infrared
colorlight X   X   X    
colorirlight X   X   X   X
colormzlight 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. The binding is NOT able to add or detect lights outside the network.

Thing Configuration

Each light needs the device ID 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.

Channels

All devices support some of the following channels:

Channel Type ID Item Type Description Thing Types
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, colorirlight, colormzlight
colorzone Color This channel supports full zone color control with hue, saturation and brightness values. colormzlight
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, colorirlight, colormzlight, whitelight
temperature Dimmer This channel supports adjusting the color temperature from cold (0%) to warm (100%). colorlight, colorirlight, colormzlight, 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.

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

Full Example

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