Notes:

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

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 accepected: 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 accepected: coolest, cool, neutral, warm, warmest, previous. 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.

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.
