Notes

Pairing

Factory reset the light bulb (video). After resetting the bulb will automatically connect.

While pairing, keep the bulb close to the coordinator (adapter).

What works is to use (very) short “on’s” and a little bit longer “off’s”, where you kill the light as soon as the bulb shows signs of turning on. Start with bulb on, then off, and then 6 “on’s”, wait in the 6th ON state. (If you try play safe and go for 7 "on's" the reset sometimes fails.)

Transition

IKEA lights only support transitions on 1 attribute at a time. If you would for example change the color temperature and brightness in 1 command, the color temperature transition is ignored.

OTA updates

This device supports OTA updates, for more information see OTA updates.

Options

How to use device type specific configuration

  • transition: Controls the transition time (in seconds) of on/off, brightness, color temperature (if applicable) and color (if applicable) changes. Defaults to 0 (no transition). The value must be a number with a minimum value of 0

  • color_sync: When enabled colors will be synced, e.g. if the light supports both color x/y and color temperature a conversion from color x/y to color temperature will be done when setting the x/y color (default true). The value must be true or false

  • identify_timeout: Sets the duration of the identification procedure in seconds (i.e., how long the device would flash).The value ranges from 1 to 30 seconds (default: 3). The value must be a number with a minimum value of 1 and with a with a maximum value of 30

  • state_action: State actions will also be published as 'action' when true (default false). The value must be true or false

Light

This light supports the following features: state, brightness, color_temp, color_temp_startup, level_config.

  • state: To control the state publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"state": "ON"}, {"state": "OFF"} or {"state": "TOGGLE"}. To read the state send a message to zigbee2mqtt/FRIENDLY_NAME/get with payload {"state": ""}.
  • brightness: To control the brightness publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"brightness": VALUE} where VALUE is a number between 0 and 254. To read the brightness send a message to zigbee2mqtt/FRIENDLY_NAME/get with payload {"brightness": ""}.
  • color_temp: To control the color temperature (in reciprocal megakelvin a.k.a. mired scale) publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"color_temp": VALUE} where VALUE is a number between 250 and 454, the higher the warmer the color. To read the color temperature send a message to zigbee2mqtt/FRIENDLY_NAME/get with payload {"color_temp": ""}. Besides the numeric values the following values are accepted: coolest, cool, neutral, warm, warmest.
  • color_temp_startup: To set the startup color temperature (in reciprocal megakelvin a.k.a. mired scale) publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"color_temp_startup": VALUE} where VALUE is a number between 250 and 454, the higher the warmer the color. To read the startup color temperature send a message to zigbee2mqtt/FRIENDLY_NAME/get with payload {"color_temp_startup": ""}. Besides the numeric values the following values are accepted: coolest, cool, neutral, warm, warmest, previous.

On with timed off

When setting the state to ON, it might be possible to specify an automatic shutoff after a certain amount of time. To do this add an additional property on_time to the payload which is the time in seconds the state should remain on. Additionally an off_wait_time property can be added to the payload to specify the cooldown time in seconds when the light will not answer to other on with timed off commands. Support depends on the light firmware. Some devices might require both on_time and off_wait_time to work Examples : {"state" : "ON", "on_time": 300}, {"state" : "ON", "on_time": 300, "off_wait_time": 120}.

Transition

For all of the above mentioned features it is possible to do a transition of the value over time. To do this add an additional property transition to the payload which is the transition time in seconds. Examples: {"brightness":156,"transition":3}, {"color_temp":241,"transition":1}.

Moving/stepping

Instead of setting a value (e.g. brightness) directly it is also possible to:

  • move: this will automatically move the value over time, to stop send value stop or 0.
  • step: this will increment/decrement the current value by the given one.

The direction of move and step can be either up or down, provide a negative value to move/step down, a positive value to move/step up. To do this send a payload like below to zigbee2mqtt/FRIENDLY_NAME/set

NOTE: brightness move/step will stop at the minimum brightness and won't turn on the light when it's off. In this case use brightness_move_onoff/brightness_step_onoff

{
  "brightness_move": -40, // Starts moving brightness down at 40 units per second
  "brightness_move": 0, // Stop moving brightness
  "brightness_step": 40 // Increases brightness by 40
  "color_temp_move": 60, // Starts moving color temperature up at 60 units per second
  "color_temp_move": "stop", // Stop moving color temperature
  "color_temp_step": 99, // Increase color temperature by 99
}

Effect (enum)

Triggers an effect on the light (e.g. make light blink for a few seconds). Value will not be published in the state. It's not possible to read (/get) this value. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"effect": NEW_VALUE}. The possible values are: blink, breathe, okay, channel_change, finish_effect, stop_effect.

Power-on behavior (enum)

Controls the behavior when the device is powered on after power loss. Value can be found in the published state on the power_on_behavior property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"power_on_behavior": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"power_on_behavior": NEW_VALUE}. The possible values are: off, on, toggle, previous.

Color options (composite)

Advanced color behavior. Can be set by publishing to zigbee2mqtt/FRIENDLY_NAME/set with payload {"color_options": {"execute_if_off": VALUE}} To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"color_options": ""}.

  • execute_if_off (binary): Controls whether color and color temperature can be set while light is off allowed values: true or false

Identify (enum)

Initiate device identification. Value will not be published in the state. It's not possible to read (/get) this value. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"identify": NEW_VALUE}. The possible values are: identify.

Linkquality (numeric)

Link quality (signal strength). Value can be found in the published state on the linkquality property. It's not possible to read (/get) or write (/set) this value. The minimal value is 0 and the maximum value is 255. The unit of this value is lqi.
