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.

Device type specific configuration #

How to use device type specific configuration

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"}

Power outage memory #

This option allows the device to restore the last on/off state when it’s reconnected to power. To set this option publish to zigbee2mqtt/FRIENDLY_NAME/set payload {"power_outage_memory": true} (or false). Now toggle the plug/switch once with the button on it, from now on it will restore its state when reconnecting to power.

Do not disturb mode #

This option allows to turn off the indicator lights between 21:00 and 09:00. To set this option publish to zigbee2mqtt/FRIENDLY_NAME/set payload {"do_not_disturb": true} (or false).

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": ""}.

Power_outage_memory (binary) #

Enable/disable the power outage memory, this recovers the on/off mode after power failure. Value can be found in the published state on the power_outage_memory property. 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 {"power_outage_memory": NEW_VALUE}. If value equals true power_outage_memory is ON, if false OFF.

Switch (center endpoint) #

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

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": ""}.

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: left_single, left_double, left_triple, left_hold, left_release, center_single, center_double, center_triple, center_hold, center_release, right_single, right_double, right_triple, right_hold, right_release.

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.

Manual Home Assistant configuration #

Although Home Assistant integration through MQTT discovery is preferred, manual integration is possible with the following configuration:
