Notes

Set default power on/off transition

Various Osram/Sylvania LED support setting a default transition when turning a light on and off.

TOPIC: zigbee2mqtt/FRIENDLY_NAME/set

{
    "set_transition": 1
}

INFO: Value is time in seconds (integer, float values are not supported)

Remember current light state

Various Osram/Sylvania LED support remembering their current state in case of power loss, or if a light is manually switched off then on. Lights will remember their respective attributes (i.e. brightness, color, saturation, etc.). NOTE: This must be executed every time you make changes to a light's attributes for it to then 'remember' it.

TOPIC: zigbee2mqtt/FRIENDLY_NAME/set

{
    "remember_state": true
}

INFO: Value is true, false (boolean)

OTA updates

This device supports OTA updates.

Options

• 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

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

Exposes

Light

This light supports the following features: state, brightness.

• 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": ""}.

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
}

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.

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.
