Notes

Light not turning off

When the light is in a transition (e.g. by sending {"brightness": 20, "transition": 5}) the bulb may not turn off via {"state": "OFF"}. You have to wait until the transition completes. This is a bug in the firmware of the light.

Light not turning on

When turning on the light with brightness 1 (e.g. by sending {"brightness" : 1}), the bulb flashes on for a fraction of a second but turns off immediately after. This can be worked around by first sending {"state": "ON"} followed by a second message setting the brightness {"brightness" : 1} or by limiting your brightness to a minimum of 2.

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.)

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

• 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_xy.

• 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_xy: To control the XY color (CIE 1931 color space) publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"color": {"x": X_VALUE, "y": Y_VALUE}} (e.g. {"color":{"x":0.123,"y":0.123}}). To read the XY color send a message to zigbee2mqtt/FRIENDLY_NAME/get with payload {"color":{"x":"","y":""}}. Alternatively it is possible to set the XY color via RGB:
  • {"color": {"r": R, "g": G, "b": B}} e.g. {"color":{"r":46,"g":102,"b":150}}
  • {"color": {"rgb": "R,G,B"}} e.g. {"color":{"rgb":"46,102,150"}}
  • {"color": {"hex": HEX}} e.g. {"color":{"hex":"#547CFF"}}

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

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.
