Description:
TRADFRI LED bulb E27 WW clear 250 lumen, dimmable
States:

Zigbee models:
IKEA / TRADFRIbulbE27WWclear250lm
Pairing 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.)

Notes:

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 Value will not be published in the state.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.

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.
