Notes
Re-pairing
Re-pairing requires the device is removed from any existing network first, this requires a factory reset if the dimmer cannot be gracefully removed from the previous network. Unfortunately the user manual does not cover this procedure, but it is quite simple: To perform a factory reset. Turn on the light, press the knob for 5 times and long press the 5th time for 3 seconds. Once reset successfully, the lamp will flicker for 5 times. To start paring, turn on the light, press the knob for 2 times and long press the 2nd time for 3 seconds. Once pairing starts, the lamp will flicker for 2 times. When pairing is complete, the lamp will flash once more.
Options
transition: Controls the transition time (in seconds) of on/off, brightness, color temperature (if applicable) and color (if applicable) changes. Defaults to0(no transition). The value must be a number with a minimum value of0state_action: State actions will also be published as 'action' when true (default false). The value must betrueorfalse
Exposes
Light
This light supports the following features: state, brightness.
state: To control the state publish a message to topiczigbee2mqtt/FRIENDLY_NAME/setwith payload{"state": "ON"},{"state": "OFF"}or{"state": "TOGGLE"}. To read the state send a message tozigbee2mqtt/FRIENDLY_NAME/getwith payload{"state": ""}.brightness: To control the brightness publish a message to topiczigbee2mqtt/FRIENDLY_NAME/setwith payload{"brightness": VALUE}whereVALUEis a number between0and254. To read the brightness send a message tozigbee2mqtt/FRIENDLY_NAME/getwith 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
stopor0. - 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
}
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.
