Notes #

Pairing #

Press and hold the button on the device for +- 10 seconds (until the blue light starts blinking and stops blinking), release and wait.

You may have to unpair the switch from an existing coordinator before the pairing process will start.

Decoupled mode #

Decoupled mode allows to turn wired switch into wireless button with separately controlled relay. This might be useful to assign some custom actions to buttons and control relay remotely. This command also allows to redefine which button controls which relay for the double switch (not supported for QBKG25LM).

Topic zigbee2mqtt/FRIENDLY_NAME/system/set should be used to modify operation mode.

NOTE: For QBKG25LM instead of system use left, center or right and leave out the button property in the payload.

Payload:

{
  "operation_mode": {
    "button": "single"|"left"|"right", // Always use single for a single switch
    "state": "VALUE"
  }
}

Values	Description
control_relay	Button directly controls relay (for single switch and QBKG25LM)
control_left_relay	Button directly controls left relay (for double switch, not supported for QBKG25LM)
control_right_relay	Button directly controls right relay (for double switch, not supported for QBKG25LM)
decoupled	Button doesn’t control any relay

zigbee2mqtt/FRIENDLY_NAME/system/get to read current mode.

Payload:

{
  "operation_mode": {
    "button": "single"|"left"|"right" // Always use single for a single switch
  }
}

Response will be sent to zigbee2mqtt/FRIENDLY_NAME, example: {"operation_mode_right":"control_right_relay"}

Switch (left endpoint) #

The current state of this switch is in the published state under the state_left property (value is ON or OFF). To control this switch publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"state_left": "ON"}, {"state_left": "OFF"} or {"state_left": "TOGGLE"}. To read the current state of this switch publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"state_left": ""}.

Switch (right endpoint) #

The current state of this switch is in the published state under the state_right property (value is ON or OFF). To control this switch publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"state_right": "ON"}, {"state_right": "OFF"} or {"state_right": "TOGGLE"}. To read the current state of this switch publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"state_right": ""}.

Power (numeric) #

Instantaneous measured power. Value can be found in the published state on the power property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"power": ""}. It’s not possible to write (/set) this value. The unit of this value is W.

Action (enum) #

Triggered action (e.g. a button click). Value can be found in the published state on the action property. It’s not possible to read (/get) or write (/set) this value. The possible values are: hold_left, single_left, double_left, release_left, hold_right, single_right, double_right, release_right, hold_both, single_both, double_both, release_both.

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.
