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.

Pairing #

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

While pairing, keep the bulb close to the CC2531 USB sniffer.

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.)

Device type specific configuration #

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). Note that this value is overridden if a transition value is present in the MQTT command payload.
hue_correction: (optional) Corrects hue values based on a correction map for matching color rendition to other lights. Provide a minimum of 2 data sets in the correction map. To build a map:
- choose one of your other lights to be the color reference
- send a sample color to both lights (reference and non-reference)
- modify hue value for non-reference light until it color matches the reference light
- take note of the in and out values, where
  - in is the hue value you sent to your reference light
  - out is the hue value you had to dial your non-reference light to
- repeat with a few other sample colors (4-5 should suffice)
Example correction map:
```
  hue_correction:
      - in: 28
          out: 45
      - in: 89
          out: 109
      - in: 184
          out: 203
      - in: 334
          out: 318
```

Light #

This light supports the following features: state, brightness, 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_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
}

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.
